面源污染视角下的岩溶区地下水资源脆弱性评价--基于PSR-物元可拓模型的分析
Evaluation of groundwater resources vulnerability from the perspective of agricultural non-point source pollution in karst area based on PSR - matter-element extension model
摘要
Abstract
Based on PSR conceptual framework, the evaluation index system of groundwater resources vulnerability is construc-ted and the groundwater resource vulnerability in karst region of Guizhou Province is evaluated using the methods of grey correla-tion weighting and the matter-element analysis. Following conclusions can be drawn:firstly, groundwater resources vulnerability in Karst region is impacted by the natural environment, especially the rainfall; the agricultural non-point source pollution and the deterioration of agricultural ecological environment are main direct controlling factors of the groundwater resources vulnerabili-ty. Secondly, for recent nine years, the stress vulnerability of groundwater resources vulnerability is at"fragile","medium frag-ile" and "fragile" levels and the state vulnerability remains at "fragile" level, which indicates that vulnerability mainly comes from stress. Thirdly, in general, the groundwater resources vulnerability in karst region of Guizhou Province is good, but fluctu-ant;the influence of drought disaster on groundwater resources vulnerability in karst region is relatively big;overall correlation is less than zero and with vulnerability risk, so optimistic opinion should not be adopted.关键词
