| Abstract: |
| 【Objective】 The study was to establish an reasonable evaluation method for regional water resources carrying capacity，so as to provide important decision basis for evaluating regional water resources carrying capacity accurately,making and applying the regional developing plans.【Method】 The set pair analysis method was introduced into water resources carrying capacity research field,and four element connection number was used to describe the differences between the evaluating indexes,and then the corresponding membership degree of regional water resources carrying capacity was determined by weight values.Thus the fuzzy four element connection number method for regional water resources carrying capacity evaluation research was established.【Result】 Applying the established method in Huaibei,Anhui Province,the practical result shows that the water resources carrying capacity of Huaibei is approaching to saturation,and the developing situation is still very severe.But with the economic development,the general status will become better.The calculation process of this method is simple and visual,and the evaluation result is reasonable and reliable,consistent with the practice.【Conclusion】 So,the evaluation method of regional water resources carrying capacity based on fuzzy four element connection number can better evaluate the different situations between the internal factors of big systems. |
