摘　　要：【目的】以白水江国家级自然保护区为例,利用GIS和RS技术,量化分析研究区大熊猫的生境特征。【方法】通过大熊猫痕迹点与研究区地形因子、植被类型、主食竹和河流分布图叠加,得出大熊猫分布区与物理环境因素和生物环境因素的关系.将居民点进行缓冲分析,与大熊猫痕迹点叠加,分析大熊猫与人类活动因素(居民点)的关系。【结果】研究得出白水江自然保护区大熊猫活动范围多在海拔1 600~2 900 m之间,痕迹点在坡度较缓(<5°)和无坡向的区域出现较多,生境中的主要植被类型是针阔叶混交林,该类型占全区域总面积的30.09%,主食竹为缺苞箭竹和青川箭竹.92.14%的痕迹点落在距水源地700 m以内的范围中,明显回避有干扰的区域,远离居民点(>3 500 m的缓冲区)。【结论】研究结果为白水江自然保护区有效保护提供了基础数据。【Objective】 With Baishuijiang National Nature Reserve(BNNR) as a case,the study aimed at quantitatively analyzing habitat characteristics of giant pandas based on GIS and RS technologies.【Method】 The physical and biological environmental factors were identified within the distribution area of giant panda by projecting the points of giant panda presence onto the distribution maps of topographic factors,vegetation types,staple food bamboo and rivers.The relationship between the distribution of giant panda and human activity factor(i.e.,residential area) was analyzed by carrying out buffer analysis on the resident area and overlaying the residential area with the points of giant panda presence.【Result】 It was showed that the altitudinal range of giant panda presence in Baishuijiang Nature Reserve was between 1 600and 2 900 m.They presented more frequently in the area with a gentle slope(<5°) or flat areas.The main vegetation type in the habitat was the conifer-broadleaf forest,which accounted for 30.09% of the total area of the reserve.The staple food of giant panda in the study area was Fargesia denudate and Fargesia rufa.The 92.14% points of giant panda presence fell within 0~700 m from water source region.Giant panda obviously kept away from the area with human activities and stayed away from the residential area(>3 500 m buffer zone of the residential area).【Conclusion】 These results could provide basic data for decision making of effective conservation of BNNR.
