摘　　要：应用遥感和地理信息系统技术,从大尺度上分析陕西凤县林麝Moschus berezovskii生境相关因子的重要性。通过对景观连接度进行模糊相对赋值,建立景观连接度评价模型,分析该地区林麝生境的景观连接度水平,评价生境的适宜性,并组建林麝生境模型。结果表明:在被研究的陕西西南部山区3 187 km2面积中,林麝最适宜生境的总面积仅有168 km2,占研究地区的5.28%,且在空间分布上处于极度破碎化状态。从景观指数上看,最适宜生境的斑块面积小,形状狭长复杂,呈孤立分布状态,对林麝的繁衍十分不利。提出了相应的生境恢复建议。The habitat of forest musk deer （Moschus berezovskii） in Fengxian County, Shaanxi Province, was analyzed using remote sensing （RS）, geographic information system （GIS） and Fragstats. With the model of landscape connectivity, constructed on the fuzzy evaluation of connectivity, several aspects such as the connectivity level, suitability assessment and fragmentation status of the musk deer habitat in the area were analyzed, and a habitat model of forest musk deer was built up. The results showed that the most suitable areas for the forest musk deer covered 168 km2, only 5.28% of all the research area （3 187 kin2）. The most suitable areas were extremely fragmentized. According to the related landscape index, the most suitable areas were all small in the region, narrow and long in figure and separated from each other. All the results showed that the habitat was not suitable for the further development of the musk deer population. [ Ch, 4 tab. 27 ref. ]
