摘要
2013年11月-2015年12月,运用样线法调查了黑龙江双河国家级自然保护区紫貂的分布和生境,基于3S技术,利用最大熵模型,对研究区域的紫貂生境进行了评价,结果表明:适宜生境面积为26033hm^2,占总面积的29.3%;不适宜生境面积为62816hm^2,占总面积的70.7%;主要道路、居民点及海拔对紫貂生境质量影响显著。
The distribution and habitat of sable in Heilongjiang Shuanghe National Nature Reserve were investigated by the sampleline From November 2013 to December 2015. Based on 3S technology and Maximum entropy model. The habitat of sable was evaluated in the study area, obtained the following results： The suitable habitat area is 26033hm2, and accounting for 29.3% of the total area. The unsuitable habitat area is 62816hm2,and accounting for 70.7% of the total area. The main roads,settlements and altitude are the main influencing factorson the habitat quality of sable.
