基于GIS的大熊猫栖息地质量研究

Research on quality of panda′s habitat in Qinling Area based on GIS

目的 分析研究大熊猫栖息地生态现状,以求加强大熊猫栖息地保护。方法 根据陕西省秦岭地区第3次大熊猫栖息地调查资料,结合GIS软件的内插分析及统计功能,从森林起源、乔木郁闭度、灌木盖度、竹子盖度及生长状况等方面进行了系统的分析研究,并绘制了各要素的空间分布图,从直观上反映了栖息地的生态状况。结果 通过对分布图中各子要素的统计,初步得出了调查区绝大部分区域是适宜大熊猫栖息的结果,为秦岭地区大熊猫栖息地质量的综合评价奠定了基础。结论 调查区内大熊猫栖息条件自东向西由好逐渐变差,但目前调查区内绝大部分区域是适宜大熊猫栖息的。

AimAnalyzing zoological status quo about habitat of panda to reinforce habitat protection.MethodsBased on interpolating analysis and statistical function of GIS,mang factors such as origin forest,shadow-covering ration,shrub-covering ration,bamboo-covering ration and growing situation are systematically analyzed acarding to the third investigation data about panda habitiat in Shaanxi-Qinling Area,and the spatial distribution graphes of each factor are mapped,which reflects the ecological condition of in habitiont directly.ResultsThrough statis tics on subordinate factor of distribution graph,intial results about each ecological factor of panda habitat are obitained.ConclusionFrom east to west the condition of panda habitat becomes from good to bad gradually, but the most investigation area is suitable for habitat of panda.
