| 摘 要： | 基于GIS技术,应用水资源脆弱性理论,采取定性与定量相结合的方法对山西省阳曲县的水资源脆弱性进行综合评价和分区评价研究。依据水资源脆弱性的特性及其变化规律,建立评价指标体系,确定评价方法;综合评价利用特尔菲法确定研究区的定级因素、因子以及指标权重;利用综合指数法计算出水资源的脆弱度;并依据分区单元分值对其水资源脆弱性级别进行了初步划分。结果表明,阳曲县水资源脆弱性分布呈现东高西低、中间高南北低的特点。

| Abstract: | On the basis of remote sensing and GIS technology and the research results of water resources vulnerability,the concept and implications of water resource vulnerability were deeply examined.Yangqu County was taken as an example to study the evaluation system of water resource vulnerability.With the Delphi method,the water resource vulnerability of Yangqu County was assessed and analyzed.The results show that the water resources of Yangqu County were generally vulnerable.And the distribution of the water resource vulnerability of Yangqu County was obtained that the value of east part was higher than that of west part,and the value of the middle part was higher than that of north part and south part.The result provided scientific basis for the water exploitation and protection in Yangqu County. |
