Study On Vulnerability Of Urban Water Source In Yunnan Plateau Basin

Vulnerability assessment of water sources is the basis of scientifically protectand ecological restoration for plateau basin urban water resources. According to thevulnerability of water sources area in plateau basin, the vulnerability indices systemare built by choosing4aspects involve14representative indices, which includehydrology weather of water sources area, ecological environment, water sourcepollution and the situation of the earth’s surface disturbance.vulnerability assessmentindices system is the basis of urban water sources in plateau basin，Using thematter-element method and extenics,the Matter-Element and Extension Sets isbuilt,and applied into the application example of songhuabai water sources.Tocompare the merits of the three methods in plateau basin urban water resources. Preferably the method is applied to one of the most suitable water source other eightcities. Meanwhile, the situation in order to avoid the vulnerability of states in thesame water source can not be compared with each other, the application of improvedfuzzy optimization model for the representation of poor highland basin vulnerabilityof urban water followed by sorting to directly reflect the plateau basin urban watervulnerability assessment size. And combining the various water sources Arcgispartition evaluate vulnerability zoning map.It turns out that the XIN Fang,BEI Miaowater sources are mild vulnerability;YUN Long,SONG Hua-ba,XIAO xiang,JIULong-dian,DONG Feng water sources are moderate vulnerability; FEI Bai,YU Dongwater sources are height vulnerability. Nine different water source evaluation ofvulnerability also varies.The results coincided with the fact water sources.
