摘　　要：藏酋猴是中国特有的物种,开展藏酋猴生境适宜性评价对合理科学保护该物种具有重要意义。基于红外相机监测技术获取的位点数据,结合植被、地形和人为干扰等3类环境因子,采用MaxEnt模型对江山市仙霞岭自然保护区中藏酋猴的生境适宜性进行评价分析。结果表明:MaxEnt模型可以较准确地预测藏酋猴生境适宜性空间分布。通过分析可知:藏酋猴中和高适宜生境主要分布在保护区东南、东北和西北部海拔较高的阔叶林内,面积为3041.10 hm^(2),占保护区总面积的43.96%;因子变量贡献分析表明,海拔、离林道距离和坡向是影响生境质量的主要因子,贡献率分别为33.30%,29.40%和12.40%。结合保护区植被、地形等栖息地条件及藏酋猴生境适宜性,需要进一步合理规划保护区的功能区,防止毛竹林面积扩张引起阔叶林的退化,提高西北部与西南部适生区的连通性,为藏酋猴种群的迁移提供安全畅通的廊道。The Macaca thibetana is an endemic species to China.Assessment on habitat suitability Macaca thibetana is very important for the conservation,which plays an important role in the rational and scientific protection of this species.To improve the conservational strategy,by using the MaxEnt model,this study evaluated and analyzed the habitat suitability based on site data obtained by infrared camera monitoring technology and three environmental factors such as vegetation,terrain,and human interference for the Macaca thibetana in Xianxialing provincial nature reserve in Jiangshan city.The results showed:the MaxEnt model could accurately predict the spatial distribution of habitat suitability for Macaca thibetana.The moderate and high suitable habitats for Macaca thibetana were mainly distributed in the southeast,northeast,and northwest of the Reserve with high altitude and broad-leaved forests.The area of moderate and high suitable habitats was 3041.10 hm^(2),accounting for 43.96%of the total area of the Reserve.Factor variable contribution analysis showed that altitude,distance from road,and slope aspect were the main factors affecting habitat quality,with contribution rates of 33.30%,29.40%,and 12.40%,respectively.Based on the results of the distribution of habitat suitability,we suggested that management department should further rationally plan the functional areas of the reserve through preventing the expansion of the bamboo forest area from causing the degradation of the broad-leaved forest,improving the connectivity between the northwest and southwest suitable habitats,and providing a safe and smooth corridor for the migration of the Macaca thibetana population.
