基于层次分析法的秦岭地区大熊猫栖息地质量评价

栖息地是大熊猫存在与否的决定因素，栖息地保护的重要性远比对大熊猫个体的保护更加重要，这是保护大熊猫必须采取的长远措施。以陕西省第三次大熊猫调查数据为基础，首先确立了影响大熊猫栖息地质量的7个指标：森林起源，乔木郁闭度，灌木盖度，竹子生长状况，竹子盖度，坡度和坡向，然后采用层次分析法计算所确立的7个评价指标的权重，并结合GIS空间叠置分析方法对7个评价指标进行叠加，获得了洋县大熊猫栖息地质量分级图。得到了以下结论：最适宜区和适宜区主要分布在调查区的东北部，不太适宜区和不适宜区分布在调查区的西部，并且自东向西逐渐变差。整体而言，调查区内大熊猫栖息地质量状况良好，适宜大熊猫的生存与繁衍。

The Quality Evaluation of Giant Panda s Habitat Based on Analytic Hierarchy Process

Habitat is the decisive factor for giant pandas' survival,and the protection of habitats is more important than each giant panda's conservation,which is the long-range measure for protection of pandas.The paper select three natural factors which affect the quality of giant panda's habitat and can be divided into seven evaluation indexes: origin forest,shadow-covering ration,shrub covering ration,bamboo covering ration,bamboo growing situation,slope and aspect,then calculate the weight value of seven indexes through Analytic Hierarchy Process(AHP) according to the data of the third giant pandas investigation in Shaanxi province,and overlay the seven indexes based on spatial analysis of GIS.Quality grade graph of giant panda's habitat is obtained,from which we can see that the optimum and fitting areas are mainly distributed in northeast,and the not-very fitting and incongruity areas are located in west,that is,the quality status has gradually become worse and worse from east to west.Finally we conclude that the quality status is good and is fit for giant panda's survival,and hope that the above results can offer advice and scientific basis for related wildlife nature conservation and administration office.
