摘　　要：以王朗自然保护区为例,考虑地质灾害影响,完善王朗大熊猫生境评价指标体系,确定海拔、坡度、坡向、距河流距离、植被、竹子分布、距道路距离、灾害点密度为评价指标。采用AHP-PCA熵权法和Maxent模型综合评价王朗大熊猫生境适宜性,基于两种方法结果预测大熊猫潜在活动区域。结果表明:(1)AHP-PCA熵权法和Maxent模型得到王朗大熊猫适宜栖息地主要在东北部及大窝函、竹根岔、长白沟,该区域植被丰富,食物水源充足,受自然灾害和人类干扰较小;(2)AHP-PCA熵权法不受物种分布影响,仅与环境指标相关,得到适宜大熊猫生境与Maxent模型预测区域有较高的重叠性,说明AHP-PCA法也可用于大熊猫生境评价且准确度较高;(3)基于两方法结果得到大熊猫栖息地潜在活动区域,主要是大窝函及竹根岔沟的西南方向延伸区域,面积约30.36 km^(2)。Taking the Wanglang Nature Reserve as an example,considering the impact of geological disasters,this study was conducted to perfect the Wanglang giant panda habitat evaluation index system,and determine the altitude,slope,aspect,distance from the river,vegetation,bamboo distribution,distance from the road,and density of disaster points as evaluation indicators.The AHP-PCA entropy weight method and Maxent model were used to comprehensively evaluate the habitat suitability of the giant panda in Wanglang,and the potential activity area of the giant panda is predicted based on the results of the two methods.The results show that:(1)By AHP-PCA entropy weight method and Maxent model,the suitable habitat for the Wanglang giant panda is mainly in the northeast and Dawohan,Zhugencha,and Changbaigou.This area is rich in vegetation,sufficient food and water sources,and is less affected by natural disasters and human disturbance.(2)The AHP-PCA entropy weight method was not affected by species distribution,but was only related to environmental indicators.The obtained suitable giant panda habitat has a high overlap with the Maxent model prediction area,indicating that the AHP-PCA method can also be used for giant panda habitat evaluation and the accuracy is high.(3)From the results of the two methods,the potential activity areas of the giant panda habitat were obtained,mainly the southwest extension area of Dawohan and Zhugenchagou,with an area of about 30.36 km^(2).
