Abstract:: 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 sub-systems: 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 socio-economic 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.
