摘要
以青海省为研究区域,以其所辖的8个行政分区作为研究单元,利用基于组合赋权的模糊物元分析法,从用水总量、用水效率、水质3个维度建立青海省水资源承载力的"三条红线"评价指标体系。结果显示:青海省水资源还具有较大的开发潜力,水资源承载能力较强。但是青海省水资源开发利用条件和程度呈现出区域性差异,西宁市和海东市水资源承载力已近饱和状态,而其余地区水资源承载力相对较强,必须因地制宜采取相应的改善措施。
Qinghai Province is chosen as the study area,and its eight administrative districts are regarded as the study units. By using the fuzzy matter-element analysis method based on the combination weights,the evaluation index system of 'Three Red Lines'for the carrying capacity of water resources in Qinghai Province is established from the dimensions of the total water use,water use efficiency and water quality. The results show that the water resources in Qinghai Province have great potential for development,and their carrying capacity is strong. However,the development conditions and utilization degrees of the water resources in Qinghai Province exhibit regional differences. The carrying capacities of water resources in Xining and Haidong cities have reached their limit values,and those in other regions are relatively stronger. It 's necessary to take appropriate measures in accordance with the local conditions.
