Abstract
Water resources carrying capacity (WRCC) is a significant foundation for scientific management of water resources that connected with development of water resources, population, society, and economy. With the rapid development of economy and society, the shortage of water quantity is becoming one of the most profound global issues. In this paper, to evaluate WRCC scientifically and reasonably, index system of WRCC was established and applied for assessing the WRCC of four cities in China by fuzzy matter element (FME) model comprehensively. The indices were weighted by entropy method. The WRCC of four cities of Beijing, Tianjin, Shanghai, and Chongqing are 2.620, 2.503, 2.590, and 2.457, respectively. The results indicated that the WRCC of four cities decreased in the order of Chongqing > Tianjin > Shanghai > Beijing. The method proposed can be applied to other evaluation issues, and the results can help managers realize the importance of water resources in developing the economy and society.
