云南省滇中地区水资源脆弱性评价

Study on water resources vulnerability assessment in Central Yunnan

阐明水资源脆弱性的概念和内涵,提出水资源脆弱性评价指标的构建原则。以云南滇中为例,构建滇中地区在水循环、社会经济和生态环境领域内的水资源脆弱性评价指标体系,运用相对偏差距离最小法对滇中地区的水资源脆弱度进行分析评价。研究结果表明:滇中地区的水资源脆弱度普遍偏高;除丽江外,其他地区水资源介于中度脆弱与重度脆弱之间。

Based on analysis of the research results of water resources vulnerability both at home and abroad, the concept and implications of water resources vulnerability were further examined and construction principles of assessment indexes of water resources vulnerability are proposed. On this basis, Central Yunnan was used as an example to establish an index system of water resources vulnerability assessment in terms of the water cycle, socio-economic status, and ecological environment. With the minimum relative deviation distance method, the water resources vulnerability of Central Yunnan was analyzed and assessed. The results showed that the water resources of Central Yunnan were generally highly vulnerable. The water resources of regions other than Lijiang showed statuses ranging from moderate vulnerability and severe vulnerability.
