本研究为云南金丝猴（Rhinopithecus bieti）的行为生态学研究提供了新的信息，为今后在老君山国家公园的保护工作做出贡献。生境评估程序用于量化土地作为物种生境的价值。分析了影响云南金丝猴生境适宜性的环境因素，绘制了研究区及周边地区适宜生境的分布图。利用GPS数据进行空间分析，研究猕猴的家距变化。使用ArcMap和R编程语言生成预测变量。我们在30米空间分辨率下准备了34个环境变量。Maxent用于分析影响适宜性的环境变量。利用卫星遥感和GIS技术，对云南金丝猴在老君山金寺场地区适宜生境的分布进行了模拟。这项研究没有描述栖息地使用的频率和强度。生境适宜性受多个变量影响，其中影响最大的是平均日温差（31.6%）、一年中最湿季降水（30.4%）、年平均降水量（17%）、归一化植被指数（5%）、湿度（4.6%）和坡向（4.5%）。该生境适宜性模型提供了云南金丝猴的分布现状信息，对合理实施保护措施具有重要意义。
We provide new information on Yunnan snub-nosed monkey (Rhinopithecus bieti) behavioral ecology, contributing to future conservation efforts within the Laojun Mountain National Park. Habitat evaluation procedures are used to quantify the value of land as a habitat for a species. We analyzed environmental variables hypothesized to influence habitat suitability for Yunnan snub-nosed monkeys, and mapped the distribution of suitable habitats across the study area and adjacent areas. Spatial analysis with GPS data was conducted to investigate home-range change of these monkeys. Predictor variables were generated using ArcMap and R programming language. We prepared 34 environmental variables at 30-m spatial resolution. Maxent was used to analyze environmental variables that contributed to suitability. Using satellite remote sensing and GIS, we modeled the distribution of suitable habitat for Yunnan snub-nosed monkeys in the Jinsichang area of the Laojun Mountains in China. This study did not describe the frequency or intensity of habitat use. Habitat suitability was affected by several variables, the most influential, as determined by permutation importance, being mean diurnal temperature range (31.6%), precipitation during the wettest quarter of the year (30.4%), average annual precipitation (17%), normalized difference vegetation index (5%), wetness (4.6%), and aspect (4.5%). This habitat suitability model provides information about the current distribution of Yunnan snub-nosed monkeys, which is important for appropriate implementation of conservation actions.
