摘　　要：2013年11月到2016年3月,在卧龙自然保护区27个位点布设了红外相机,其中10个位点成功拍摄到雪豹影像,基于MaxEnt模型预测雪豹在卧龙的适宜栖息地。结果显示:雪豹的适宜栖息地面积为345km2,占总面积的12%。其中,279km2(81%)位于核心区,49km2位于缓冲区,17km2位于实验区。植被类型、年均温度和坡向是影响雪豹栖息地选择的主要环境因子。雪豹主要选择年均温度为-8~0℃的阳坡,最偏好的植被类型为草甸。Between November 2013 and March 2016, infrared-triggered camera were installed in 27 dif- ferent loci in Wolong National Nature Reserve, Sichuan, China. Among them, 10 cameras photographed snow leopards successfully. Based on these 10 loci and MaxEnt model, the snow leopard distribution map was developed in Wolong. The area of available habitat was 345 km2, covering 12% of the total area. 279 km2（81% ） of the suitable habitat were located in the core area, 15% in the buffer area, and only 5 % in the experimental area. The main factors influencing the habitat selection by snow leopards include the vegetation form, the average annual temperature and aspect of the habitat. Snow leopards in Wolong preferred the sunny slope at an annual temperature of -8 ℃ ~ 0℃. The favorite landcover type is meadow. The studies provided the basic data for the protection of suitable habitats.
