Comprehensive evaluation of water resource carrying capacity based on fuzzy recognition

The purpose of this paper is to establisha fuzzy recognit ion(FR)method to solve water carrying capacity evaluation. Based on the data structure of the related indices,the ranking feature value of each region can be obtained through Fuzzy Recognition method,and the evaluation contribution ratio of each index also can be obtained. An evaluat ion case study of 30 regions of China shows the objectivity and practicability of FR.
