摘要
川金丝猴是我国特有的濒危物种,秦岭山系是其分布区之一。本文在生境模型MAXENT的支持下,利用物种痕迹点、自然环境及人类干扰空间数据,评价秦岭山系川金丝猴的生境适宜性。结果表明:川金丝猴偏好在远离人类活动干扰,海拔1 300 m以上,靠近河流的山地森林中活动。川金丝猴生境主要分布在秦岭的中西部地区,面积达8 853.8 km2,占秦岭山系总面积的15.3%。现有保护区保护了31.6%的川金丝猴生境,为更有效保护秦岭川金丝猴及其生境,有必要新建或扩建保护区,使生境集中分布区得到有效保护,同时提高生境之间的连通性,促进金丝猴种群的交流与迁徙。
The Rhinopithecus roxllanae is an endangered species endemic to China, and Qinling Mountain is one of its distribution regions. According to the species trace points, natural environment and human interference data, the MAXENT model was applied to assess the habitat suitability for Rhinopithecus roxllanae in Qinling Mountain. Results showed that the Rhinopithecus roxllanae preferred the forests with high elevation （ 〉 1 300 m） , near the river and far away from human activities. The habitat of Rhinopitheeus roxllanae mainly distributed in middle and western Qinling Mountain with an area of 8 853.8 km^2 , occupying 15.3% of the mountain＇s total area. At present, around 31.6% of its habitat is protected as nature reserves in Qinling Mountain. In order to protect this species and its habitat more effectively, it is necessary to expand nature reserve areas, which can protect the concentrated habitat region, improve the connectivity among habitat units, as well as promote the exchange and migration of Rhinopitheeus roxllanae populations.
