针对水资源供需矛盾问题，采用相关评价指标与函数评价方法，对丹江口水源区水资源的脆弱性进行了评价。结果表明，目前该区域水资源脆弱性整体上程度低、抗压性强，南水北调中线工程前期调水会在不同程度上增加各区域的水资源脆弱性，但并不改变整个水源区的脆弱性等级；水资源脆弱性大体自西向东升高，经济发达地区高于欠发达地区。根据评价结果，从实施用水总量控制、提高水资源利用效率、开发新水源和治理水污染等方面提出了相应的适应性对策。%In view of the contradiction of water supply and demand, Danjiangkou water source area is taken as the research re-gion, the water resources vulnerability of the region is evaluated by related indexes and function evaluation method. The analysis results show that the water vulnerability is at a low degree and has high integrated resistance at present. The pre-stage water di-version of Middle Route Project of South-to-North Water Diversion will increase the strength of vulnerability, but does not change the vulnerability level of the whole water source area. The water vulnerability increases from west to east, and the vulnera-bility in developed areas is higher than that in less developed areas. According to the results, some adaptive countermeasures are recommended, including applying the gross water utilization control, improving the water use efficiency, developing new water sources and controlling water pollution and so on.
