    老化,作为一个全球性的人口问题,其特点是快速增长,这推动了人们医疗保健意识的提高。健康基地的出现迎合了这一市场需求。因此,确定适合健康活动的潜在区域和建设健康基地,称为健康目标区域(WTAs),成为关键的第一步。目前,常用的识别方法大多基于传统的统计方法,通常很复杂,笨重、并受到主观假设的潜在风险,影响WTAs识别结果的可靠性。长寿水平是反映一个地区自然和社会经济环境的综合指标,使其成为最能反映区域健康环境状况的指标。
    本研究提出将寿命水平作为WTAs识别的基准,以简化识别过程并减少主观偏见对结果的影响。以云南省129个县级单位为研究对象。首先,地球探测器(GD)用于探索长寿水平与地理环境之间的复杂相互作用,以确定区域健康因素。其次,使用ArcGIS和地理加权回归(GWR),这项研究调查了不同健康因素的作用,最终对WTA进行分类和分级。
    云南省的长寿水平呈现出多点聚类的模式,形成了三大长寿区。显著影响寿命水平的因素包括年平均降水量,日照时间,PM2.5含量,人均可支配收入,旅游景点的密度,以及从居民区到医院的距离。根据长寿程度和影响因素的贡献率,云南省的WTA分为三个级别和两个类型(自然和综合)。
    我们的研究旨在建立长寿水平与健康基础选择之间的联系,通过长寿现象与地理环境的关系探索区域健康因素,确定健康基地的潜在建筑区域(即,WTAs),为健康基础的精确选择提供新的见解,有效提高选址的科学性,促进人口健康,并以更好的健康为全球老龄化进程做出贡献。
    UNASSIGNED: Aging, as a global demographic issue, is characterized by its rapid growth, which drives an increase in people\'s healthcare awareness. The emergence of wellness bases caters to this market demand. Therefore, the identification of potential areas suitable for wellness activities and the construction of wellness bases, referred to as Wellness Target Areas (WTAs), becomes a crucial first step. Currently, commonly used identification methods are mostly based on traditional statistical approaches, which are often complex, cumbersome, and subject to potential risks of subjective assumptions, affecting the reliability of WTAs identification results. Longevity level serves as a comprehensive indicator reflecting the natural and socio-economic environment of a region, making it the most indicative of the regional wellness environment status.
    UNASSIGNED: This study proposes using longevity level as the benchmark for WTAs identification to simplify the identification process and reduce the impact of subjective bias on the results. The study focuses on 129 county-level units in Yunnan Province. Firstly, the Geodetector (GD) is utilized to explore the complex interaction between the longevity level and the geographical environment to determine regional wellness factors. Secondly, using ArcGIS and geographical weighted regression (GWR), the study investigates the role of different wellness factors, ultimately classifying and grading the WTAs.
    UNASSIGNED: The longevity level in Yunnan Province exhibits a pattern of multi-point clustering, forming three major longevity regions. Factors that significantly influence longevity level include annual average precipitation, sunshine duration, PM2.5 content, per capita disposable income, density of tourist attractions, and distance from residential areas to hospitals. Based on the degree of longevity and the contribution rate of influencing factors, Yunnan Province\'s WTAs are classified into three levels and two types (natural and comprehensive).
    UNASSIGNED: Our study aims to establish a connection between longevity level and the selection of wellness bases, exploring regional wellness factors through the relationship between longevity phenomena and geographical environment, identifying potential construction areas for wellness bases (i.e., WTAs), providing new insights for the precise selection of wellness bases, effectively enhancing the scientificity of site selection, promoting population health, and contributing to the global aging process with better health.

    在互联网时代,在线数字痕迹已成为研究景区和游客在线关注购买行为的新途径。公众在各大搜索平台上的信息搜索是潜在游客对景点的关注和兴趣的一系列表现,但是很少有关于如何关注的研究,兴趣和信息搜索影响潜在游客产生真实的购买行为。
    本文选取短视频平台的四个维度,旅游网站,搜索引擎和社交媒体,综合衡量云南省优质景区的线上关注度,然后基于AISAS模型的相关变量建立灰色关联层次分析法,对影响旅游者购买行为的主次因素进行实证分析。
    (1)从不同平台景点的在线关注度来看,公众在四大类媒体平台上的景点在线关注强度依次为旅游网站,搜索引擎,短视频和社交媒体(2)从空间分布特征来看,云南省优质景区的网上关注度分布不均,也就是说,高星级景点的关注度与星级和受欢迎程度之间存在很大差异,而低星级景区的关注度与其星级和知名度相差不大(3)从空间集聚特征来看,云南省优质景区综合在线关注呈现“东北方高密度多核联动”的空间集聚特征,和南方的次高密度“(4)影响潜在游客购买行为的因素是分享体验,吸引注意力,产生兴趣和搜索信息。
    通过探索云南省优质景区线上关注度的形成机制及其空间分异机制,本研究不仅丰富了“旅游信息源→潜在游客→需求驱动→旅游信息搜索→旅游偏好→目的地选择→购买决策→旅游体验→真实游客→旅游后感受→关注反馈→旅游信息源”的逻辑链,同时也在一定程度上拓宽了出行偏好理论和AISAS行为模型的应用场景和应用边界。
    UNASSIGNED: In the era of the Internet, online digital traces have become a new way to study the online attention of scenic spots and tourists\' purchase behavior. The public\'s information search on major search platforms is a series of manifestations of potential tourists\' attention and interest in scenic spots, but there are few studies on how attention, interest and information search affect potential tourists to generate real purchase behavior.
    UNASSIGNED: This paper selects four dimensions of short video platform, travel website, search engine and social media to comprehensively measure the online attention of high-quality scenic spots in Yunnan Province, and then establishes a gray association analytic hierarchy process based on the relevant variables of the AISAS model to empirically analyze the primary and secondary factors affecting tourists\' purchase behavior.
    UNASSIGNED: (1) From the perspective of the online attention of scenic spots on different platforms, the intensity of the public\'s scenic spots online attention on the four types of media platforms is in the order of travel websites, search engines, short videos and social media (2) From the perspective of spatial distribution characteristics, the online attention of high-quality scenic spots in Yunnan Province is unevenly distributed, that is, there is a big difference between the attention of higher star scenic spots and their star rating and popularity, while the attention of low-star scenic spots is not much different from their star rating and popularity (3) From the perspective of spatial agglomeration characteristics, the comprehensive online attention of high-quality scenic spots in Yunnan Province presents the spatial agglomeration characteristics of \"the multi-core linkage of high-density in the east and north, and sub-high-density in the south\" (4) The factors influencing the purchase behavior of potential tourists are sharing experience, attracting attention, generating interest and searching information.
    UNASSIGNED: By exploring the formation mechanism of high-quality scenic spots online attention in Yunnan Province and the mechanism of its spatial differentiation, this study not only enriches the logical chain of \"tourism information source → potential tourists → demand driven → tourism information search → travel preference → destination selection → purchase decision → travel experience → real tourists → feelings after traveling → focus on feedback → tourism information source,\" but also broadens the application scenarios and application boundaries of travel preference theory and AISAS behavior model to a certain extent.

    作物系统被认为是农业温室气体排放的最大来源。确定影响种植系统的关键类别和因素对于减少这些排放至关重要。大多数研究都是从单一作物或作物类别的角度关注种植系统的碳收支。量化多样化种植系统碳预算的综合研究,包括农田和园林作物,仍然有限。本研究旨在通过量化多样化种植系统的碳预算来填补这一空白,澄清他们的碳属性,并在系统的不同分类中确定关键作物类别和影响因素。本研究分析了云南省19种作物组成的多元化种植系统的碳收支,中国西南部,使用基于“摇篮到农场”生命周期理念的基于作物的净温室气体平衡方法。将作物分为三个级别的类别,以评估种植系统内分类对其碳平衡的潜在影响。结果表明,云南的多元化种植系统是一个显著的碳汇,净封存量为33.1Mt二氧化碳当量,总排放量为37.4公吨二氧化碳当量,和总封存70.5MtCO2当量。谷物,蔬菜,爱好作物是碳排放的主要贡献者,占41.61%,21.87%,和15.37%,分别。谷物作物对碳固存的贡献也最大,为53.18%。香蕉的单位面积排放量最高(11.45t二氧化碳当量ha-1),而核桃的固存率最高(20.64tCO2eqha-1)。此外,这项研究强调了减少温室气体排放的有效策略,例如减少氮肥的使用,将反应性氮损失降至最低,控制稻田的甲烷排放。通过阐明碳动态和作物类别的影响,这项研究为可持续农业实践和政策提供了见解。
    Cropping systems are considered the largest source of agricultural GHG emissions. Identifying key categories and factors affecting cropping systems is essential for reducing these emissions. Most studies have focused on the carbon budget of cropping systems from the perspective of a single crop or crop category. Comprehensive studies quantifying the carbon budget of diversified cropping systems, including farmland and garden crops, are still limited. This study aims to fill this gap by quantifying the carbon budget of diversified cropping systems, clarifying their carbon attributes, and identifying key crop categories and influencing factors within different classifications of the system. This study analyzed the carbon budget of a diversified cropping system consisting of 19 crops in Yunnan Province, southwestern China, using a crop-based net greenhouse gas balance methodology based on the \"cradle-to-farm\" life cycle idea. Crops were categorized into three levels of categories to assess the potential impact of categorization within the cropping system on its carbon balance. Results showed that Yunnan\'s diversified cropping system is a significant carbon sink, with net sequestration of 33.1 Mt CO2 eq, total emissions of 37.4 Mt CO2 eq, and total sequestration of 70.5 Mt CO2 eq. Cereals, vegetables, and hobby crops were the main contributors to carbon emissions, accounting for 41.61%, 21.87%, and 15.37%, respectively. Cereal crops also made the largest contribution to carbon sequestration at 53.18%. Bananas had the highest emissions per unit area (11.45 t CO2 eq ha-1), while walnuts had the highest sequestration (20.64 t CO2 eq ha-1). In addition, this study highlights effective strategies to reduce greenhouse gas emissions, such as reducing nitrogen fertilizer use, minimizing reactive nitrogen losses, and controlling methane emissions from rice fields. By elucidating the impact of carbon dynamics and crop categories, this study provides insights for sustainable agricultural practices and policies.

    螺旋体是一种通过硬蜱传播的螺旋体。在日本发现之后,这种病原体已经在世界各地被发现,并且越来越多地被证实是引起发热疾病的人类病原体,即复发性发热。它的存在已在中国东北得到证实。然而,在包括云南省在内的中国南部,关于米亚莫托伊和其他硬蜱传复发性螺旋体的信息很少,蜱和动物种类丰富,许多人都居住和参观娱乐。
    对于本研究,我们采集了蜱虫的样本,野生动物,和来自云南省不同县的家畜寄主。从样品中提取核酸,使用16SrRNA特异性靶基因片段的聚合酶链反应(PCR)确认了B.miyamotoi和其他复发性发热螺旋体的存在。然后扩增阳性样品的flaB和glpQ基因的部分基因组。用SPSS20软件对其分布进行统计学差异分析。部分16SrRNA的序列,分析了flaB和glpQ基因组,并构建了系统进化树。
    总共8260个样品,包括2304个蜱,收集4120只小型哺乳动物和1836只家畜宿主的血液,以筛查B.miyamotoi和其他复发性发热螺旋体的感染。牛和羊是主要寄主,而Rhipicephalusmicroplus,奈帕氏血盐,H.kolonini和Ixodesovatus被确定为重要的载体宿主,具有高患病率或广泛分布。只有一只卡罗利小母鼠(小鼠)和一只SorexAlpinus(泼妇)被证实对复发性发热螺旋体呈阳性。蜱垂直传播的证据也得到了证实。两种已知的B.miyamotoi菌株和一种新型复发性发热螺旋体,B.类似泰勒里的特工,被证实并描述为他们的宿主适应,突变,以及人类传播和溢出的潜在风险。
    我们的研究结果为云南省病媒和动物宿主中复发性发热螺旋体的大样本量提供了新的证据,并为进一步调查提供指导,监测和监测这种病原体。
    UNASSIGNED: Borrelia miyamotoi is a spirochete species transmitted via hard ticks. Following its discovery in Japan, this pathogen has been detected around the world, and is increasingly confirmed as a human pathogen causing febrile disease, namely relapsing fever. Its presence has been confirmed in the Northeast China. However, there is little information regarding the presence of B. miyamotoi and other hard-tick-borne relapsing fever spirochetes in southern China including Yunnan province, where tick and animal species are abundant and many people both inhabit and visit for recreation.
    UNASSIGNED: For the present study, we collected samples of ticks, wildlife, and domestic animal hosts from different counties in Yunnan province. Nucleic acids from samples were extracted, and the presence of B. miyamotoi and other relapsing fever spirochetes was confirmed using polymerase chain reaction (PCR) for the 16S rRNA specific target gene fragment. The positive samples were then amplified for partial genome of the flaB and glpQ genes. Statistical differences in its distribution were analyzed by SPSS 20 software. Sequence of partial 16S rRNA, flaB and glpQ genome were analyzed and phylogenetic trees were constructed.
    UNASSIGNED: A total of 8260 samples including 2304 ticks, 4120 small mammals and 1836 blood of domestic animal hosts were collected for screening for infection of B. miyamotoi and other relapsing fever spirochetes. Cattle and sheep act as the main hosts and Rhipicephalus microplus, Haemaphysalis nepalensis, H. kolonini and Ixodes ovatus were identified as the important vector host with high prevalence or wide distribution. Only one Mus caroli (mouse) and one Sorex alpinus (shrew) were confirmed positive for relapsing fever spirochetes. Evidence of vertical transmission in ticks was also confirmed. Two known strains of B. miyamotoi and one novel relapsing fever spirochetes, B. theileri-like agent, were confirmed and described with their host adaptation, mutation, and potential risk of spreading and spillover for human beings.
    UNASSIGNED: Our results provide new evidence of relapsing fever spirochetes in vector and animal hosts in Yunnan province based on large sample sizes, and offer guidance on further investigation, surveillance and monitoring of this pathogen.

    傣族主要产于云南省,中国,在那里有着悠久的传统。最新的全国人口普查报告称,云南有1,259,000名Dai族。本研究以云南3504个傣族聚居区为研究对象,通过县记录确定。利用ArcGIS空间分析平台,我们首先使用最近邻指数和地理集中度指数等指标来评估他们的定居点空间分布格局。然后,我们应用地理探测器来研究它们分布的潜在机制。研究结果表明:(1)云南省傣族聚落总体上具有凝聚力空间分布,然而,存在不均匀的分布模式,有许多人口稠密的地区和“两个核心”的模式,一条皮带,一个区域,和两点“;(2)Dai族聚落主要占据垂直分区的第三梯度,主要在澜沧江发现的Dai族聚居地,Ayeyarwaddy,和红河流域。相反,Dai族混合聚居区主要位于澜沧江,红色,和怒江流域;(3)通过地理探测器的分析表明,民族文化因素在确定Dai住区的空间分布中最为重要,其次是社会经济和自然因素;(4)居民区的分布受这些居民区内Dai族人口比例的影响很大。Dai族聚集定居点通常位于平坦的斜坡上,海拔范围为500至1000m,坡度为0°-5°。同时,Dai混合定居点分布在海拔1000-2000m,坡度为5°-15°的缓坡上。研究表明,Dai族定居点的位置受到环境因素的强烈影响,并且从相似的起源中得到了重要的解释。
    The Dai people are primarily found in Yunnan Province, China, and have a long heritage there. The latest national census reports that Yunnan is home to 1,259,000 individuals of the Dai ethnic group. This study focuses on 3504 Dai settlements in Yunnan, identified through county records. Using the ArcGIS spatial analysis platform, we first evaluated their settlements\' spatial distribution patterns using metrics like the nearest neighbor index and geographic concentration index. Then, we applied geodetector to investigate the underlying mechanisms of their distribution. The results reveal that: (1) Dai settlements in Yunnan Province generally have a cohesive spatial distribution; at the provincial level, however, there is an uneven distribution pattern, with many densely populated areas and a pattern of \"two cores, one belt, one area, and two points\"; (2) The Dai settlements predominantly occupy the third gradient of the vertical zonation, with Dai gathering settlements primarily found in the Lancang, Ayeyarwaddy, and Red River basins. Conversely, Dai mixed settlements are mainly situated in the Lancang, Red, and Nu River basins; (3) Analysis via geodetector indicates that ethnocultural factors are the most significant in determining the spatial distribution of the Dai settlements, followed by socio-economic and natural factors; (4) The distribution of settlements is significantly influenced by the proportion of the Dai population within these settlements. Dai gathering settlements are typically located on flat slopes with elevations ranging from 500 to 1000 m and slopes of 0°-5°. Meanwhile, Dai mixed settlements are found on gentle slopes with elevations of 1000-2000 m and slopes of 5°-15°. The study reveals that the location of Dai settlements is strongly influenced by environmental considerations and has a significant explanation from similar origins.

    Four new wood-inhabiting fungi were found in Southwestern China within the genera Phanerochaete, Phlebiopsis, Asterostroma, and Vararia of the families Phanerochaetaceae and Peniophoraceae, belonging to the orders Polyporales and Russulales individually. Combined with their morphological characteristics and molecular biological evidence, the present study describes them as new fungal taxa. Asterostroma yunnanense is characterized by the resupinate, membranaceous to pellicular basidiomata with a cream to salmon-buff hymenial surface, hyphal system dimitic bearing simple-septa, thin- to thick-walled, yellowish brown asterosetae with acute tips, and thin-walled, echinulate, amyloid, globose basidiospores. Phanerochaete tongbiguanensis is characterized by the resupinate basidiomata with a white to cream hymenial surface, a monomitic hyphal system with simple-septa generative hyphae, the presence of subclavate cystidia covered with a lot of crystals, and oblong ellipsoid basidiospores (6-9 × 3-4.5 µm). Phlebiopsis fissurata is characterized by the membranaceous, tuberculate basidiomata with a buff to slightly brown hymenial surface, a monomitic hyphal system with simple-septa, conical cystidia, and broadly ellipsoid. Vararia yingjiangensis is characterized by a corky basidiomata with a pinkish buff to cinnamon-buff hymenial surface, cracking, yellowish dichohyphae with slightly curved tips, subulate gloeocystidia, and thick-walled, ellipsoid basidiospores (6.5-11.5 × 5-7 µm). The phylogenetic analyses of ITS + nLSU revealed that the two new species were nested into the genera Phanerochaete and Phlebiopsis within the family Phanerochaetaceae (Polyporales), in which Phanerochaete tongbiguanensis was sister to P. daliensis; Phlebiopsis fissurata was grouped with P. lamprocystidiata. Two new species were clustered into the genera Asterostroma and Vararia within the family Peniophoraceae (Russulales), in which Asterostroma yunnanense was sister to A. cervicolor; Vararia yingjiangensis formed a single branch.

    背景:棘球蚴病流行于中国西部和北部的9个省。2012年和2016年云南省包虫病流行病学调查显示包虫病病例。
    目的:了解云南省包虫病的空间分布和流行病学特征,为云南省包虫病的预防和控制提供依据。
    方法:基于中国疾病预防控制信息系统(CISDCP),从2021年到2022年,对36家医院和34个疾病控制中心报告的包虫病病例进行了调查和流行病学分析。排除标准包括疑似病例,同样的病例只统计了一次,而不是云南的病例。共调查了705例,其中397例适用于统计学分析。在这397个案例中,对187例病例进行流行病学追踪调查。所有数据均使用Excel数据库中的双重条目输入,通过双输入比较进行纠错。利用ArcGIS10.1软件对云南省包虫病病例资料进行分析,生成包虫病分布密度图。所有统计分析均使用SPSS17.0进行,包括卡方检验,线性回归检验和Logistic单变量和多元回归分析。
    结果:云南省89个县共发现397例。病例数前三的州为大理(38.1%),迪庆(10.1%),和昆明(8.3%),排名前五位的县是剑川(9.1%),香格里拉(8.3%),洱源(7。6%),鹤庆(6.9%),和大理地区(5.0%)。不同地区之间存在显著差异。CISDCP的病例报告率(33.8%)较低;2002年CISDCP报告了第一例病例,最高病例数为50例(2017年)。确诊和临床病例分别占62.5%和37.5%,分别。然而,90.9%的包虫病病例由医院系统报告,社区中只有9.1%的包虫病病例是通过积极筛查发现的。两种病例检测方法差异有统计学意义。包虫病的大多数病例发生在农牧民(75.1%)和学生(9.1%)中。此外,汉族(43.6%)和白族(26.2%)的感染率高于其他民族,肝(87.7%)和肺(6.8%)是最常见的囊肿形成部位。在分析的案例中,对187例进行流行病学分析,47.1%的病例早期临床症状不明显。Logistic回归分析结果显示,教育水平,狗在家庭中的存在(以前或现在),洗手(偶尔或不洗手)是与包虫病感染有关的因素。55.6%的病例发生在流行地区,44.4%的病例在非流行地区。在非流行地区的83例病例中,只有4个病例去过流行区,有生活史,工作,旅行,或者在包虫病流行地区狩猎。
    结论:在整个云南省报告了包虫病病例,大部分分布在云南西部,建议在该地区加强包虫病的控制。我们建议今后开展流行病学调查,根据医院或CISDCP新发现病例的线索。医院新发现的病例提供了线索,全面确定了病例发生的地点和应该在哪里进行疫点调查。
    BACKGROUND: Echinococcosis is prevalent in 9 provinces in Western and Northern China. An epidemiological survey of echinococcosis in 2012 and 2016 showed cases of echinococcosis in Yunnan Province.
    OBJECTIVE: To understand the spatial distribution and epidemiological characteristics of echinococcosis in Yunnan for the prevention and control of echinococcosis and to reduce the risk of infection in Yunnan Province.
    METHODS: Based on the China Information System for Disease Control and Prevention (CISDCP), echinococcosis cases reported from 36 hospitals and 34 Centers for Disease Control were investigated and epidemiologically analyzed from 2021 to 2022. The exclusion criteria included suspected cases, same case only counted once and cases not from Yunnan. A total of 705 cases were investigated, of which 397 cases were suitable for statistical analysis. In these 397 cases, epidemiological investigation was tracked in 187 cases. All data were inputted using double entry in the Excel database, with error correction by double-entry comparison. The data on echinococcosis cases in Yunnan Province were analyzed by ArcGIS 10.1 software to generate a density map of echinococcosis distribution. All statistical analyses were conducted using SPSS 17.0, including the chi-square test, linear regression test and logistic univariate and multivariate regression analyses.
    RESULTS: A total of 397 cases were found in 89 counties in Yunnan Province. The number of cases in the top three prefectures were Dali (38.1%), Diqing (10.1%), and Kunming (8.3%), and the top five counties were Jianchuan (9.1%), Shangri La (8.3%), Eryuan (7. 6%), Heqing (6.9%), and Dali Districts (5.0%). There were significant differences between the different areas. The case reporting rate by CISDCP (33.8%) was low; the first case was reported by CISDCP in 2002, and the highest number of cases was 50 (2017). Confirmed and clinical cases accounted for 62.5% and 37.5%, respectively. However, 90.9% of the cases of hydatid disease were reported by the hospital system, and only 9.1% of the cases of hydatid disease were found in the community through active screening. The difference between the two methods of case detection was statistically significant. Most of the cases of echinococcosis were found in farmers/herdsmen (75.1%) and students (9.1%). In addition, Han (43.6%) and Bai (26.2%) had a higher incidence of infection than other nationalities, and the liver (87.7%) and lung (6.8%) were the most common sites of cyst formation. Among the analyzed cases, 187 were epidemiologically analyzed and the clinical symptoms were not obvious in the early stage in 47.1% of cases. The results of logistic regression analysis showed that the age group, education level, presence of dogs in the family (either previously or currently), and handwashing (occasionally or not) were factors related to echinococcosis infection. 55.6% of cases were in endemic areas, and 44.4% of cases were in non-endemic areas. Among 83 cases in non-endemic areas, only 4 cases had been to endemic areas and had a history of living, working, travelling, or hunting in echinococcosis epidemic areas.
    CONCLUSIONS: Cases of echinococcosis were reported throughout the entire Yunnan province, with the majority distributed in Western Yunnan, suggesting that echinococcosis control should be strengthened in this area. We suggest that an epidemiological investigation should be carried out in the future, based on the clues from newly discovered cases in hospitals or from the CISDCP. The newly discovered cases in the hospital provided clues to comprehensively determine the location of cases and where epidemic spot investigation should be conducted.
