摘要
针对东江流域的地区特点,以目前社会和经济发展水平为基础,确立水资源安全分级标准,采用层次分析法确定各指标的权重,用多级模糊综合评判法对东江流域水资源安全进行评价,最后得出从2000年到2007年东江流域各行政区的水资源安全度呈下降的趋势。
On the basis of the regional characteristics of Dongjiang River Basin,and the current social and economic development,this study established classification standard of water security.Analytic Hierarchy Process（APH） was adopted to determine the weight of every index.The multi-grade fuzzy comprehensive evaluation method was used for safety evaluation of water sources in Dongjiang River Basin.It concluded that during 2000～2007 the level of water security in the Dongjiang River Basin tended to decrease.
