贵州省生态环境敏感性评价方法研究

Study on the Assessment Method of Ecological Environmental Sensitivity in Guizhou Province

对贵州省生态环境敏感性评价方法的选用原则、评价程序和评价方法要点进行了探讨。拟采用层次分析法计算各指标的权重,采用均匀分布函数确定各指标的隶属度,然后采用模糊综合评判方法对各县域单元的土壤侵蚀、石漠化、生物多样性及生境、酸雨敏感性进行定量评价,进而对区域生态环境敏感性进行综合评价。

In this paper the assessment method,selection principle,assessment process of ecological environmental sensitivity in Guizhou province and its key elemen were discussed.The analytical hierarchy process was used to canculate the relative importance of every index,and even distribution function was selected to define the subordinate degree of every index,and fuzzy synthetical judgement was adopted to assess the sensitivity of the eco-environment for all counties in Guizhou province.
