Fuzzy comprehensive evaluation model for groundwater resources carrying capacity in Hongxinglong agricultural settlement substation

摘要

Owing to the overexploitation for groundwater thus leading the water lowering of groundwater, the formation and enlargement of the cone of depression in Hongxinglong Branch Bureau, this paper using the fuzzy mathematics to establish fuzzy comprehensive evaluation model for groundwater resources carrying capacity. The evaluation results indicated that the groundwater resources carrying capacity of Youyi, 852, 597, 853, Shuangyashan, Shuguang, Beixing, Hongqiling farm are the level one. they hold greatly development potentials and the state of groundwater carrying capacity is fairly optimistic; the groundwater resources carrying capacity of Baoshan farm is level two. The groundwater resource development and utilization has been a considerable scale, but there is still a certain development potential; The groundwater resources carrying capacity of farm Raohe, 291, Jiangchuan is level three, which show that the groundwater resources carrying capacity has approached their limits. They should control strictly groundwater exploitation intensity. The research result provides the scientific basis for the groundwater protection and sustainable utilization in Hongxinglong Branch Bureau and even Sanjiang Plain.
