摘　　要：综合海拔、植被类型、主食竹分布等环境因子,基于MaxEnt模型对九寨沟自然保护区进行大熊猫生境的适宜性评价,发现大熊猫偏好海拔2 700~3 500 m、坡度10°左右有竹子分布且郁闭度在75%以上的林地活动。在此基础上叠加地灾影响范围,根据适宜生境的分布特征和地灾影响情况,识别大熊猫栖息地保护的重点区域,以期更有针对性地开展大熊猫及其栖息地的保护工作。Based on the MaxEnt model,the environmental conditions,including elevation,vegetation type and staple diet bamboo distribution,were used to evaluate the suitability of giant panda habitats in Jiuzhaigou Nature Reserve.It was found that giant pandas preferred woodland with bamboo distribution at an altitude of 2700~3500 m and a slope of about 10°,and the canopy density above 75%.Furthermore,the impact range of geological disasters and distribution of suitable habitats of giant pandas were superimposed to identify the key areas for protection of giant panda habitats,in orde to carry out more targeted protection of giant pandas and their habitats.
