  • 文章类型: Journal Article
    随着全球土地利用/土地覆盖(LULC)和气候变化,典型喀斯特地区的生态恢复力已成为人们关注的焦点。其未来发展趋势及其对自然和人为因素的空间响应对于理解生态脆弱区对人类行为的变化至关重要。然而,还缺乏相关的定量研究。该研究系统分析了近20年来中国西南地区典型喀斯特LULC变化的特征。借鉴景观生态学研究范式,建立了潜在-弹性-稳定性ER评估模型。揭示了空间分布的特征和异质性,年度演变,在过去和未来不同的共享社会经济途径和代表性集中途径(SSP-RCP)情景下,ER的发展趋势。此外,利用空间计量经济模型揭示了ER的空间效应响应机制,提出了促进西南地区可持续发展的适应性发展战略。研究发现:(1)在过去的20年里,中国西南地区的LULC呈加速变化趋势,ER总体下降,并且存在显著的空间异质性,显示了“西比东大”的空间分布格局,南方比北方大,西部的减少速度比东部慢。\“(2)在相同的SSP方案下,随着RCP排放浓度的增加,最低复原力的区域显著增加,弹性最高的区域减少了。(3)林地是西南地区单位面积ER的最大贡献者,草地是主要的LULC类型,这对研究区域的ER有显著影响。(4)平均降水量和归一化植被指数(NDVI)是研究区ER的显著自然驱动因素,和经济增长,创新,产业结构的优化促进了西南地区的ER。总的来说,定量评估和基于多情景的建模的集成不仅为理解变化模式和响应机制提供了新的视角,同时也为世界其他典型喀斯特地区实现可持续发展提供了有价值的参考。
    With the global land use/land cover (LULC) and climate change, the ecological resilience (ER) in typical Karst areas has become the focus of attention. Its future development trend and its spatial response to natural and anthropogenic factors are crucial for understanding the changes of ecologically fragile areas to human behavior. However, there is still a lack of relevant quantitative research. The study systematically analyzed the characteristics of LULC changes in Southwest China with typical Karst over the past 20 years. Drawing on the landscape ecology research paradigm, a potential-elasticity-stability ER assessment model was constructed. Revealing the characteristics and heterogeneity of the spatial distribution, annual evolution, and development trend of ER in the past and under different scenarios of shared socioeconomic pathways and representative concentration pathways (SSP-RCP) in the future. In addition, the spatial econometric model was utilized to reveal the spatial effect response mechanism of ER, and adaptive development strategies were proposed to promote the sustainable development of Southwest China. The study found that : (1) In the past 20 years, the LULC in Southwest China showed an accelerated change trend, the ER decreased declined in general, and there was significant spatial heterogeneity, showing the spatial distribution pattern of \"west is larger than east, south is larger than north, and reduction in the west was slower than that in the east.\" (2) Under the same SSP scenario, with the increase of RCP emission concentration, the area of the lowest-resilience increased significantly, and the area of the highest-resilience decreased. (3) The woodland was the largest contributor to ER per unit area in the Southwest China, and grassland was the main LULC type, which had a prominent impact on the ER of the study area. (4) The average precipitation and the normalized difference vegetation index (NDVI) were significant natural drivers of ER in the study area, and the economic growth, innovation, and optimization of industrial structure contributed to the ER of Southwest China. Overall, the integration of quantitative assessment and multi-scenario-based modeling not only provides new perspectives for understanding the pattern of change and response mechanisms, but also provides valuable references for other typical Karst regions around the world to achieve sustainable development.

    牦牛(Bosgrunniens)具有出色的区域适应性,使其能够在青藏高原独特的生态位中茁壮成长。它的生存依赖于肠道微生物组的复杂平衡,适应恶劣的环境条件。尽管有文献记载的细菌和真菌在维持肠道稳态和支持免疫功能方面具有重要意义,在理解牦牛肠道微生物群的组成和功能如何沿海拔-温度梯度变化方面仍有很大差距。这项研究旨在通过采用16SrRNA和ITS扩增子测序技术来分析和比较不同海拔和暴露于不同温度的牦牛的肠道微生物组,从而填补这一空白。研究结果表明,肠道细菌和真菌的多样性存在细微差异,伴随着各种海拔高度和温度梯度的分类组成发生重大变化。值得注意的是,Firmicutes,放线菌,拟杆菌在所有群体中都是占主导地位的门,放线菌在LZF组中的比例最高(35.77%)。功能预测分析揭示了LZF组和氨基酸代谢和生物合成相关的代谢途径之间的显著关联。这表明放线菌在增强牦牛营养吸收和代谢方面具有潜在作用。此外,我们的发现表明,牦牛的微生物群可能通过调节厚壁菌与拟杆菌的比例来增强能量代谢和分解代谢,有可能减轻温度变化的影响。使用宏基因组技术分析了三个不同组之间的肠道细菌和真菌群落的变化。我们的发现表明,在低海拔地区牦牛中表现出显着增加的微生物属在很大程度上是有益的。总而言之,我们的研究调查了不同海拔和温度范围内牦牛肠道细菌和真菌种群的变化。此外,这些结果增强了对肠道微生物组成和变异性的理解,从微生物的角度提供了关于干批牦牛的环境恢复能力的观点。
    The yak (Bos grunniens) exhibits exceptional regional adaptability, enabling it to thrive in the distinctive ecological niches of the Qinghai-Tibet Plateau. Its survival relies on the intricate balance of its intestinal microbiome, essential for adapting to harsh environmental conditions. Despite the documented significance of bacteria and fungi in maintaining intestinal homeostasis and supporting immune functions, there is still a substantial gap in understanding how the composition and functionality of yak gut microbiota vary along altitude-temperature gradients. This study aims to fill this gap by employing 16S rRNA and ITS amplicon sequencing techniques to analyze and compare the intestinal microbiome of yaks residing at different elevations and exposed to varying temperatures. The findings demonstrate subtle variations in the diversity of intestinal bacteria and fungi, accompanied by significant changes in taxonomic composition across various altitudes and temperature gradients. Notably, Firmicutes, Actinobacteriota, and Bacteroidota emerged as the dominant phyla across all groups, with Actinobacteriota exhibiting the highest proportion (35.77%) in the LZF group. Functional prediction analysis revealed significant associations between the LZF group and metabolic pathways related to amino acid metabolism and biosynthesis. This suggests a potential role for actinomycetes in enhancing nutrient absorption and metabolism in yaks. Furthermore, our findings suggest that the microbiota of yaks may enhance energy metabolism and catabolism by modulating the Firmicutes-to-Bacteroidota ratio, potentially mitigating the effects of temperature variations. Variations in gut bacterial and fungal communities among three distinct groups were analyzed using metagenomic techniques. Our findings indicate that microbial genera exhibiting significant increases in yaks at lower altitudes are largely beneficial. To sum up, our research investigated the changes in gut bacterial and fungal populations of yaks residing across diverse altitude and temperature ranges. Moreover, these results enhance comprehension of gut microbial makeup and variability, offering perspectives on the environmental resilience of dry lot feeding yaks from a microbial angle.

    陆地湿地生态系统挑战生物多样性-生态系统功能理论,这通常将高物种多样性与稳定的生态系统功能联系起来。生态系统生态学中的一个悬而未决的问题是,共生的泥炭苔藓的组合是否有助于泥炭地生态系统过程的稳定性。我们进行了两个物种(虎尾草,泥炭藓培养基)替代系列介观实验,以评估阻力,弹性,在轻度和深水位下降下,净生态系统CO2交换(NEE)的回收率。我们的结果表明,温和的地下水位下降对NEE有积极作用,对泥炭藓混合物没有明显作用。我们的研究表明,泥炭苔藓混合物的碳吸收能力对温和的水位下降相当有弹性,但受到更深的干旱条件的严重影响。共存的泥炭苔藓物种似乎仅略微增强了泥炭苔藓混合物的碳吸收功能(即NEE恢复到扰动前水平的能力)的弹性。这些发现表明,在干旱条件下,共同发生的泥炭藓苔藓的组合对泥炭地生态系统功能的稳定性仅有很小的贡献。最重要的是,我们的研究结果突出表明,预测的严重干旱会严重影响泥炭地的汇能力,对泥炭藓混合物只有很小的增容作用。
    Terrestrial wetland ecosystems challenge biodiversity-ecosystem function theory, which generally links high species diversity to stable ecosystem functions. An open question in ecosystem ecology is whether assemblages of co-occurring peat mosses contribute to the stability of peatland ecosystem processes. We conducted a two-species (Sphagnum cuspidatum, Sphagnum medium) replacement series mesocosm experiment to evaluate the resistance, resilience, and recovery rates of net ecosystem CO2 exchange (NEE) under mild and deep water table drawdown. Our results show a positive effect of mild water table drawdown on NEE with no apparent role for peat moss mixture. Our study indicates that the carbon uptake capacity by peat moss mixtures is rather resilient to mild water table drawdown, but seriously affected by deeper drought conditions. Co-occurring peat moss species seem to enhance the resilience of the carbon uptake function (i.e. ability of NEE to return to pre-perturbation levels) of peat moss mixtures only slightly. These findings suggest that assemblages of co-occurring Sphagnum mosses do only marginally contribute to the stability of ecosystem functions in peatlands under drought conditions. Above all, our results highlight that predicted severe droughts can gravely affect the sink capacity of peatlands, with only a small extenuating role for peat moss mixtures.

    20世纪和21世纪城市化的发展带来了前所未有的生态安全问题。城市发展与内部生态安全之间的不平衡日益受到关注。
    基于城市发展过程和生态系统恢复力的特征,构建了相应的城市化评价体系(“规模-结构-效益”)和生态系统恢复力评估模型(“抗性-适应性-恢复”),以探索各个维度的变化,并分析了时空变化。使用耦合协调度(CCD)模型和地理和时间加权回归(GTWR)分析城市化与生态恢复力耦合协调水平的驱动效应。
    (1)从2005年到2020年,城市化水平提高(分别从0.204提高到0.264),而生态恢复力水平逐渐下降(分别从0.435下降到0.421)。城市化的空间分布相当稳定,具有“高东北低西南”的区域分布格局;然而,生态恢复力的空间分布格局基本上是相反的。(2)在学习期间,城市化和生态恢复力的协调水平有所提高,从0.524增加到0.540。然而,主要协调类型保持不变,超过46%处于基本协调阶段。相对发展类型以滞后的城市化阶段为主,滞后的生态恢复力和同步发展阶段所占比例较小,空间分布在一个块状的集群中。(3)GTWR的运行结果表明,整个区域的核心维度是尺度,benefit,和结构,各维度的影响表现出明显的空间异质性。相对发展水平不同的城市也具有不同的中心维度。本研究将为经济建设与生态韧性不协调地区的城市发展协调提供支持,并将有助于城市地区的可持续发展。
    UNASSIGNED: The growth of urbanization in the 20th and 21st centuries has resulted in unprecedented ecological security issues. The imbalance between urban development and internal ecological security is a growing concern.
    UNASSIGNED: Based on the urban development process and the characteristics of ecosystem resilience, the corresponding urbanization evaluation system (\"scale-structure-benefit\") and ecosystem resilience assessment model (\"resistance-adaptability-restoring\") were constructed to explore the changes in each dimension as well as to analyze the spatial and temporal changes and driving effects of the coupled coordination level of urbanization and ecological resilience using the coupled coordination degree (CCD) model and geographically and temporally weighted regression (GTWR).
    UNASSIGNED: (1) From 2005 to 2020, urbanization levels increased (from 0.204 to 0.264, respectively), whereas the level of ecological resilience gradually decreased (from 0.435 to 0.421, respectively). The spatial distribution of urbanization is rather steady, with a \"high-northeast low-southwest\" pattern of regional distribution; however, the spatial distribution pattern of ecological resilience is essentially the reverse. (2) During the study period, there was an improvement in the level of coordination between urbanization and ecological resilience, with an increase from 0.524 to 0.540. However, the main coordination type remained the same, with over 46% being at the basic coordination stage. The relative development type was dominated by the lagging urbanization stage, with the lagging ecological resilience and synchronous development stages accounting for a smaller proportion, and the space was distributed in a block-like cluster. (3) The running results of the GTWR show that the core dimensions of the whole region are scale, benefit, and structure, and the impact of each dimension shows obvious spatial heterogeneity. Cities with different levels of relative development also have different central dimensions. This research will provide support for the coordination of urban development in areas where economic construction and ecological resilience are not coordinated, and will contribute to the sustainable development of urban areas.

    本地鸡生产系统(ICPS)具有多种使用价值和生态系统服务。在过去的几年里,ICPS因其对家庭粮食安全的可能贡献而得到认可,创收,野生动物保护,改善妇女的生活。本研究旨在收集,第一次,关于三种不同农业生态系统中ICPS的综合信息(热带,亚热带,和亚温带)的印度喜马拉雅地区(IHR)及其在传统社区的粮食和经济安全中的作用。在这个研究区域,ICPS是半广泛的,提供自家种植的饲料和临时夜间庇护所。在亚温带农业生态学中,雌性比雄性拥有更多的本地鸡群(p=0.170)。亚温带农业生态系统中的家庭的羊群规模和热带牲畜单位(鸡TLU)明显更大(p≤0.001)。然而,在热带和亚热带农业生态学中,牲畜多样性指数(LDI)显着提高(p≤0.001)。由于其生存能力和适应性,亚温带地区的家庭高度重视本地鸡(p≤0.001)。在过去的1年中,亚温带农业生态学中,成年鸟类的绝对数量显着增加(p≤0.001)。亚温带农业生态中的成年鸟类死亡率为9%,在热带和亚热带农业生态系统中占14%和15%,分别。在亚温带农业生态学中,更大的羊群大小转化为显着更高的产蛋量(p≤0.001),随后每个家庭每月的鸡蛋消费量显着增加(p≤0.001)。在亚温带农业生态学中,家庭饮食多样性得分显著(p≤0.001)更高。同样,在亚温带农业生态学中,ICPS的平均年收入显着提高(p≤0.001),占家庭收入的18%。亚温带地区的ICPS营销链相对较短。在所有农业生态中,冬季,本地鸡肉和鸡蛋的需求显着增加(p≤0.001)。ICPS凋落物用作农家肥,增强生态韧性。在所有农业生态中,扩展本地鸡肉生产系统最常提到的三个障碍是疾病,捕食者,和缺乏小鸡的可用性。ICPS有助于粮食和营养安全,经济稳定,以及这个丘陵脆弱的生态系统中的生态恢复力。即使这个系统是自给自足的,管理和健康干预措施可以提高产量和生产力。
    The indigenous chicken production system (ICPS) has several use values and ecosystem services. In the last few years, ICPS has been recognized for its possible contribution to household food security, income generation, wildlife protection, and bettering the women\'s lives. This study aimed to collect, for the first time, comprehensive information about ICPS in three different agro-ecologies (tropical, sub-tropical, and sub-temperate) of the Indian Himalayan Region (IHR) and its role in food and economic security of traditional communities. In this study region, ICPS is semi-extensive, providing homegrown feed and temporary night shelter. In sub-temperate agro-ecology, females owned non-significant (p = 0.170) more indigenous chicken flocks than males. Households in sub-temperate agro-ecologies had significantly (p ≤ 0.001) larger flock sizes and tropical livestock units (chicken-TLU). However, the livestock diversity index (LDI) was significantly higher (p ≤ 0.001) in tropical and subtropical agro-ecology. The households in the sub-temperate region highly (p ≤ 0.001) valued indigenous chicken because of its survivability and adaptability. In absolute numbers significant (p ≤ 0.001) higher numbers of adult birds died in past 1 year in sub-temperate agro-ecology. The mortality rate of adult birds in sub-temperate agro-ecology was 9%, and it was 14 and 15% in tropical and sub-tropical agro-ecologies, respectively. In sub-temperate agro-ecology, larger flock size translated into significantly higher (p ≤ 0.001) egg production and subsequently a significant (p ≤ 0.001) higher egg consumption per household per month. In sub-temperate agro-ecology, households\' dietary diversity score was significantly (p ≤ 0.001) higher. Similarly, the average annual income from ICPS was significantly higher (p ≤ 0.001) in sub-temperate agro-ecology and accounted for 18% of household income. ICPS\' marketing chain was relatively short in the sub-temperate region. In all agro-ecologies, indigenous chicken and egg demand was significantly higher (p ≤ 0.001) in the winter. ICPS litter is used as farmyard manure, enhancing ecological resilience. In all agro-ecologies, the three most frequently cited obstacles to extending the indigenous chicken production system are illnesses, predators, and a lack of chicks availability. ICPS contributes to food and nutritional security, economic stability, and ecological resilience in this hilly and fragile ecosystem. Even though the system is self-sustaining, management and health interventions can increase production and productivity.

    本文比较了支撑创意文化产业(CCI)危机的应急韧性和生态韧性的结合。首先介绍了CCI危机的社会建构及其应急韧性霸权实践的三个特征(时间,灾难话语,以及对美学数字化的适应),并揭示了多种话语-从文化统计技术到公司财务建模-构建了“弹性即赤字”的意识形态。与这种方法相反,本文提出了生态韧性的三个特征:注重转型和长期;韧性作为一种体面的战略和网络资源;审美数字化作为一种根本性的适应性实践。审查艺术影响和文化政策报告,借鉴生态,女权主义和文化韧性研究,并分析了亚洲的数字文化活动(新加坡LGBT文化节,粉红点),文章认为,生态恢复力为文化生态提供了新的能力,可以培育公平的工作,艺术创新,经济增长和文化活力。
    This article compares the conjunctions of emergency resilience and ecological resilience that underpin the creative cultural industry (CCI) crisis. It first introduces three characteristics that socially construct the CCI crisis and its hegemonic practice of emergency resilience (time, disaster discourse, and the adaptation of aesthetic digitalization) and exposes multiple discourses - from the technologies of cultural statistics to corporate financial modelling - that construct an ideology of \'resilience-as-deficit\'. In contrast to this approach, the article develops three characteristics of ecological resilience: a focus on transition and the long term; resilience as a decentred strategy and networked resource; and aesthetic digitization as a radical praxis of adaptability. Examining arts impact and cultural policy reports, drawing on ecological, feminist and cultural resilience studies, and analysing a digital cultural event in Asia (the Singapore LGBT cultural festival, Pink Dot), the article argues that ecological resilience offers new capacities towards a cultural ecology that can nurture fair work, artistic innovation, economic growth and cultural vitality.

    微生物垫是复杂的生态组合,自前寒武纪以来一直存在于岩石记录中,并且仍然可以在现存的边缘化环境中找到。这些结构被认为是高度稳定的生态系统。在这项研究中,我们评估了现代圆顶形成微生物垫的生态稳定性,水位波动,位于CuatroCiénegas盆地的高盐池塘,墨西哥。我们从2016年到2019年对该地点进行了宏基因组采样,检测到2250属细菌和古菌,只有<20属于丰富的分类群(>1%)。微生物群落以变形杆菌为主,Euryarchoota,拟杆菌,Firmicutes,和蓝细菌,并且对干扰敏感,导致即使在门一级也有很高的分类学替代,在整个2016-2019年研究期间,古菌从[公式:见正文]1-4%显著增加到[公式:见正文]33%。尽管核心群落代表了大多数微生物群落(>75%),样品之间的相对丰度发生了显著变化,从2017年的10.2%到2019年的0.05%的Coleofasculus丰度变化证明了这一点。尽管季节之间的功能差异很微妙,共现网络表明季节之间的生态相互作用不同,在雨季增加了一个新的模块,以及枢纽分类单元的潜在转移。样品之间的功能组成稍微相似,但是碳水化合物等基本过程,氨基酸,核酸代谢在样品中分布广泛。主要的碳固定过程包括硫氧化,固氮,和光合作用(产氧和产氧),以及Wood-Ljundgahl和Calvin周期。
    Microbial mats are complex ecological assemblages that have been present in the rock record since the Precambrian and can still be found in extant marginalized environments. These structures are considered highly stable ecosystems. In this study, we evaluate the ecological stability of dome-forming microbial mats in a modern, water-level fluctuating, hypersaline pond located in the Cuatro Ciénegas Basin, Mexico. We conducted metagenomic sampling of the site from 2016 to 2019 and detected 2250 genera of Bacteria and Archaea, with only <20 belonging to the abundant taxa (>1%). The microbial community was dominated by Proteobacteria, Euryarchaeota, Bacteroidetes, Firmicutes, and Cyanobacteria, and was compositionally sensitive to disturbances, leading to high taxonomic replacement even at the phylum level, with a significant increase in Archaea from [Formula: see text]1-4% to [Formula: see text]33% throughout the 2016-2019 study period. Although a core community represented most of the microbial community (>75%), relative abundances shifted significantly between samples, as demonstrated by changes in the abundance of Coleofasciculus from 10.2% in 2017 to 0.05% in 2019. Although functional differences between seasons were subtle, co-occurrence networks suggest differential ecological interactions between the seasons, with the addition of a new module during the rainy season and the potential shift in hub taxa. Functional composition was slightly more similar between samples, but basic processes such as carbohydrate, amino acid, and nucleic acid metabolisms were widely distributed among samples. Major carbon fixation processes included sulfur oxidation, nitrogen fixation, and photosynthesis (both oxygenic and anoxygenic), as well as the Wood-Ljundgahl and Calvin cycles.

    UNASSIGNED: The COVID-19 pandemic is interrupting domestic and global food supply chains resulting in reduced access to healthy diverse diets. Hawai\'i has been described as a model social-ecological system and it has been suggested that indigenous agro-ecosystems have the potential to be highly productive and resilient under changing land-use and climate change disturbance. However, little research has yet been conducted exploring the disruption and resilience of agro-ecosystems in Hawai\'i caused by the COVID-19 pandemic. The breadfruit tree (Artocarpus altilis; Moraceae) is a signature, multi-purpose-tree of the complex perennial agro-ecosystems systems in Oceania.
    UNASSIGNED: This case study explores the ways in which the breadfruit agro-ecosystems of Hawai\'i have shown resilience during the COVID-19 pandemic.
    UNASSIGNED: Our study suggests that breadfruit has increased its value as a subsistence crop during the COVID-19 pandemic, even in a developed economy like Hawai\'i, and that resilience of Hawaiian breadfruit agroe-cosystems during a crisis can be supported through cooperatives and food-hubs.

    弹性是应对林业不确定未来的关键概念。近年来,它越来越受到研究和实践的关注。然而,缺乏对林业背景下的复原力意味着什么以及如何将其付诸实施的共同理解。这里,我们对最近关于林业背景下的恢复力的森林科学文献进行了系统的回顾,综合如何定义和评估弹性。
    根据对255项研究的详细回顾,我们分析了工程弹性的概念,生态复原力和社会生态复原力被用于森林科学。显然,大多数研究都应用了工程复原力的概念,将弹性量化为干扰后的恢复时间。工程恢复力最常用的两个指标是基础面积增量和植被覆盖,而生态恢复力研究通常集中在植被覆盖和树木密度上。相比之下,文献中使用的重要社会生态复原力指标是社会经济多样性和自然资源存量。在全球变化的背景下,我们预计采用更全面的社会生态复原力概念的研究将会增加,但这不是观察到的趋势。
    我们的分析指出了这三个弹性概念的嵌套性,这表明它们是互补的而不是矛盾的。这也意味着各种弹性方法不必成为该概念实施的障碍。我们为根据管理层选择最合适的弹性概念和指标提供指导,干扰和应用上下文。
    UNASSIGNED: Resilience is a key concept to deal with an uncertain future in forestry. In recent years, it has received increasing attention from both research and practice. However, a common understanding of what resilience means in a forestry context and how to operationalise it is lacking. Here, we conducted a systematic review of the recent forest science literature on resilience in the forestry context, synthesizing how resilience is defined and assessed.
    UNASSIGNED: Based on a detailed review of 255 studies, we analysed how the concepts of engineering resilience, ecological resilience and social-ecological resilience are used in forest sciences. A clear majority of the studies applied the concept of engineering resilience, quantifying resilience as the recovery time after a disturbance. The two most used indicators for engineering resilience were basal area increment and vegetation cover, whereas ecological resilience studies frequently focus on vegetation cover and tree density. In contrast, important social-ecological resilience indicators used in the literature are socioeconomic diversity and stock of natural resources. In the context of global change, we expected an increase in studies adopting the more holistic social-ecological resilience concept, but this was not the observed trend.
    UNASSIGNED: Our analysis points to the nestedness of these three resilience concepts, suggesting that they are complementary rather than contradictory. It also means that the variety of resilience approaches does not need to be an obstacle for operationalisation of the concept. We provide guidance for choosing the most suitable resilience concept and indicators based on the management, disturbance and application context.

    草原喀斯特沙漠化治理平衡了生态修复和农村生态畜牧业发展的生态效益和经济效益。在全球变化和人类活动加剧的背景下,喀斯特荒漠化治理下草地生态系统的脆弱性日益明显,增强草原的生态恢复力和生态系统服务是一个迫切需要解决的问题。在本文中,CNKI文献,WOS核心数据库和Goolgle学者被用作搜索源,确定了179篇与草地生态系统脆弱性和生态恢复力研究相关的文章。本研究系统综述了草地生态系统脆弱性研究进展,分析了草地生态系统服务功能与草地生态系统脆弱性和恢复力的关系。从相互反馈的角度指出了岩溶地区增强GES的方向,协同关系,和GES的作用机制,脆弱性,和韧性。并强调喀斯特荒漠化地区应围绕GES的供求关系为区域环境的可持续发展提供生态基础,服务流的权衡协同,以及增强生态恢复力,从而巩固了喀斯特荒漠化防治的有效性,增强GES,帮助乡村振兴。
    Karst desertification control of grasslands balances the ecological and economic benefits of ecological restoration and rural ecological animal husbandry development. In the context of global changes and intensified human activities, the fragility of grassland ecosystems under karst desertification control is becoming increasingly evident, and enhancing the ecological resilience and ecosystem services of grasslands is an issue that urgently needs to be addressed. In this paper, the CNKI literature, WOS core databases and Goolgle scholar were used as search sources, identifying 179 articles related to the study of grassland ecosystem vulnerability and ecological resilience. This research systematically reviewed the progress of grassland ecosystem vulnerability research and analyzed the relationship between grassland ecosystem services (GESs) and grassland ecosystem vulnerability and resilience. The direction of enhancing GESs in karst areas is indicated in terms of the reciprocal feedback, synergistic relationship, and mechanism of action of GESs, vulnerability, and resilience. It is also emphasized that the karst desertification area should provide an ecological foundation for the sustainable development of the regional environment around the supply-and-demand relationship of GESs, the trade-off synergy of service flow, and the enhancement of ecological resilience, thereby consolidating the effectiveness of karst desertification control, enhancing GESs, and helping rural revitalization.
