- Abstract:
-
Evaluation of water resources carrying capacity is a basic measure of regional water security. According to the water security issues existing in developing and utilizing water resources, such as the descending of groundwater level and ‘hanging pump’, the criteria system for water resources carrying capacity evaluation was established by grey correlation analysis. Entropy-based fuzzy matter-element assessment model was established based on the conventional fuzzy matter-element model, and introduced the entropy theory into the calculation of weight. This method was applied to evaluate the water resources carrying capacity of fifteen farms belonging to Jiansanjiang branch bureau in 2008. The results showed that the water resources carrying capacities of Farm 859, Qindeli, Qianshao, Qianfeng, Honghe, Yalvhe, Erdaohe and Nongjiang are in grade Ⅰ, their water resources still have upper carrying capacities; the water resources carrying capacities of Farm Shengli, Daxing, Qinglongshan and Qianjin are in grade Ⅱ, their water resources exploitation and utilization still have some potential; the water resources carrying capacities of Farm Qixing, Chuangye and Hongwei are in grade Ⅲ, their groundwater resources carrying capacities have been close to saturation. The results play an important role in providing scientific evidences for water resources protection and sustainable utilization in Jiansanjiang branch bureau.
