摘　　要：大熊猫生境状况关系到大熊猫的长期生存与繁衍，从大尺度来评价大熊猫生境状况有利于生境的保护与保护区的规划与建设，从而有利于大熊猫的保护。在大熊猫生物学与行为生态学的研究成果基础上，通过广泛的野外调查，在地理信息系统（GIS）和遥感（RS）技术支持下，利用大熊猫生境结构理论模型，选取海拔、坡度、植被类型、竹子分布等评价因子，系统地研究了秦岭山系大熊猫生境的分布、生境质量与空间格局、以及生境保护现状，并提出了相应的生境保护对策。研究表明：①秦岭山系的大熊猫生境面积约为44万hm^2，80％的生境分布于海拔1500～2400m之间；②由于交通、河流以及沿途的开发建设，整个生境被分为大小不等的若干部分；③当前的大熊猫保护区与拟建的保护区及走廊带之间互相连接，形成了一个较为完整的保护区体系，保护了70％以上的大熊猫生境。研究结果能为该山系的大熊猫生境保护提供依据。Giant pan In this pa slope, ve evaluated per, using GIS and remote sensing （RS） techniques, selecting several factors including elevation, getation and bamboo distribution, habitats of giant pandas in Qinling mountain range were based on extensive field survey and previous researches. Spatial patterns and protection condition of pandas＇ habitat were analyzed and some countermeasures on Results show that： ①giant pandas＇ habitats in Qinling mountai 80% of which distribute between 1500 and 2400 m. ②The wh habitats＇ protection were brought forward. n range cover an area of about 440 000 ha, ole habitat are separated into several due to the transportation, rivers and other surrounding developments. ③The current nature reserve proposed reserves and corridors were connected with each other, forming a protection network for pandas in Qinling mountain range. More than 70% of habitats were protected in this network. research will contribute to the protection of giant pandas＇ habitat in this mountain range.
