四川金丝猴(Rhinopithecusroxellana)是中国特有的珍稀濒危灵长类动物。对川金丝猴的种群分布变化进行研究对其保护至关重要。我们的研究通过整合实地调查获得的数据,对四川金丝猴的种群分布进行了全面调查,保护区,和历史记录,并使用地理信息系统(GIS)来探索各个时间段的分布变化,包括历史(中-晚更新世),最近(1980-2000),和当前(2001-2023年)。研究结果表明,与历史时间范围相比,川金丝猴的分布范围发生了显着变化。值得注意的是,在1980年至2000年之间,分布面积急剧下降。分析表明,四川省最南端的四川金丝猴分布县已从会理北移至康定。此外,四川省的分布变化不仅以栖息地面积减少为特征,而且以垂直分布带减少为特征。四川东北部海拔1000m以下的地区,比如广安市,巴中市,达州市,南充市,不再支持四川金丝猴的存在。目前,分布范围限制在9,000至4000米的两个主要山脉的海拔上,分别是在9,000和5,000米之间。需要采取整体方法来保护该物种。建立流动走廊可以在加强当前分布地区的整体连通性方面发挥关键作用。此外,我们建议采用分层方法来保护当前的栖息地。应实施空间差异化保护措施,优先保护重点栖息地,同时监测非重点栖息地的人为活动,以防止进一步分裂和隔离猴子的分布区域。
The Sichuan golden snub-nosed monkey (Rhinopithecus roxellana) is a rare and endangered primate species endemic to China. Conducting research on the population distribution changes of the Sichuan golden snub-nosed monkey holds paramount importance for its conservation. Our study represented a comprehensive investigation into the population distribution of the Sichuan snub-nosed monkey by integrating data acquired from field surveys, protected areas, and historical records and using Geographic Information Systems (GIS) to explore changes in distribution across various time periods, including the historical (the Mid-to-Late Pleistocene), recent (1980-2000), and current (2001-2023). The research findings demonstrate a significant shift in the distribution range of the Sichuan golden snub-nosed monkey compared to historical time frames. Notably, between 1980 and 2000, there was a sharp decline in distribution area. Analyses revealed that the southernmost distribution county for the Sichuan golden snub-nosed monkey in Sichuan Province has shifted northward from Huili to Kangding. Furthermore, distribution changes in Sichuan Province are not solely characterized by a reduction in habitat area but also by a decrease in vertical distribution zones. Regions in the northeastern part of Sichuan with elevations below 1000 m, such as Guang\'an City, Bazhong City, Dazhou City, and Nanchong City, no longer support the presence of the Sichuan golden snub-nosed monkey. At present, the distribution range is confined to elevations between 1000 and 4000 m in the two major mountain ranges of Qionglai and Minshan. A holistic approach is required to safeguard this species. The establishment of movement corridors can play a critical role in enhancing the overall connectivity of current distribution areas. Additionally, we propose implementing a hierarchical approach to protect current habitats. Spatially differentiated conservation measures should be implemented to prioritize the protection of key habitats while simultaneously monitoring anthropogenic activities in non-key habitats to prevent further fragmentation and isolation of the monkey\'s distribution areas.
