石羊河流域水资源脆弱性评价

根据石羊河流域水资源的现状,运用AHP法,依据流域内各指标的可获得性和代表性,建立了石羊河流域水资源脆弱性评价指标体系,从自然脆弱性、人为脆弱性和承载脆弱性等方面,对该流域水资源脆弱性进行整体评价.结果表明,石羊河流域水资源综合脆弱性G=3.12,水资源处于中等脆弱状态.其自然脆弱性、人为脆弱性和承载脆弱性分别为1.00、3.16、4.17,其中自然脆弱性对流域水资源的综合脆弱性影响最大,符合流域水资源现状.

Vulnerability Evaluation of Water Resources in Shiyang River Basin

According to the current situation of water resources in Shiyang River Basin as well as the procurability and representativeness of all indexes, using the AHP method, the evaluation index system of water resource vulnerability was established, and indexes influencing nature vulnerability, artificial vulnerability and carrying vulnerability were analyzed. Combined with status of the basin, the Overall vulnerability of water resources was evaluated. The results showed that composite vulnerability G = 3.12, in the medium state. The nature vulnerability, artifi- cial vulnerability and carrying vulnerability were 1.00, 3.16 and 4.17, of which the largest impact on composite vulnerability is nature vulner- ability, which coincided with current situation of the basin.
