野生哺乳动物生态廊道构建 --以云豹为例

Construction of Ecological Corridor for Wild Mammals-Taking Clouded Leopard as an Example

利用最大信息熵模型对大湘南区域的云豹生境进行了适宜性评价分析,并根据适宜性评价分析结果利用地理信息系统软件(ArcGIS)的最小累积阻力模型构建云豹保护廊道,结果表明,大湘南地区云豹生境面积为2718.87 km^(2),占全区域总面积的6.5%,其中适宜生境460.11 km^(2),次适宜生境2258.76 km^(2),云豹生境集中分布于远离人类且植被保持良好的中高海拔山地森林;根据最小累积阻力模型生成的湘南地区潜在云豹保护廊道共23条,其保护廊道总长为13580 km,并构成了“三核两横四纵”的生物多样性保护网络构架,提出优化生态网络的有效措施。

The maximum information entropy model was used to evaluate the suitability of the clouded leopard habitat in southern Hunan,and the clouded leopard protection corridor was constructed using the minimum cumulative resistance model of geographic information system software(ArcGIS)according to the results of the suitability evaluation and analysis.The result showed that the clouded leopard habitat area in greater southern areas of Hunan was 2718.87 km^(2),accounting for 6.5%of total area in the whole areas,including 460.11 km^(2) suitable habitat and 2258.76 km^(2) suboptimal habitat,and clouded leopard habitat mainly concentrated in mountain forests of intermediate altitude and high altitude which were away from human but kept good vegetation.In southern areas of Hunan,there were 23 hidden protection corridors of clouded leopard which were formed according to the minimal cumulative resistance model;the overall length of them was 13580 km,and besides,it constructed the“three nuclear,two horizontal and four vertical”biodiversity conservation network framework and put forward the effective measure to optimize ecological network.
