摘要
水资源承载力评价是水资源安全管理的基础。以喀斯特典型省份广西壮族自治区为研究对象,选取评价指标并用熵权法赋权,构建模糊综合评价模型,对2013年广西各地市水资源承载力进行综合评价分析。评价结果显示:2013年广西水资源承载力状况总体较好,其中桂林市、柳州市处于理想可承载状态,贵港市处于不可承载状态,其他地市均处于可承载状态。从各子系统来看,供需子系统总体状况较好,防城港市的供需子系统评价指数最高,南宁市和贵港市的评价指数最低;生态环境子系统评价指数普遍较低,桂林市的评价指数最高;社会经济子系统方面,柳州市、桂林市和防城港市评价指数最高,而贵港市的评价指数最低。评价结果对广西及各地市水资源规划和水资源可持续开发利用具有一定的借鉴和参考价值。
Water resource carrying capacity evaluation is the basis of water security management.Selecting Guangxi Province,a typical karst region as the study area,we selected the evaluation indices from three subsystems：water resource,socio-economic and ecological environment.The fuzzy comprehensive evaluation model of water resource carrying capacity was constructed to evaluate water resource carrying capacity of Guangxi in 2013 using entropy weight method.It was shown that the overall water resource carrying capacity in Guangxi in 2013 was in good condition.The water resource carrying capacity of Guilin City and Liuzhou City are in an ideal state.The water resource carrying capacity of Guigang City is in a non-carrying state.Other cities are in a carrying state.Seeing each subsystem,the overall water resource subsystem is in good condition,among which the highest index of water resource subsystem evaluation is found in Fangchenggang City,and the lowest one is observed in Nanning City and Guigang City.The ecological subsystem evaluation index is generally low,among which the highest index is found in Guilin City.The highest index of socioeconomic subsystem evaluation is observed in Liuzhou City,Guilin City and Fangchenggang City,while the lowest is observed in Guigang City.The evaluation results of this method can help water resource planning and sustainable development and utilization in Guangxi and other regions.
