单县地下水超采综合治理分析

Analysis of the Comprehensive Improvement of Groundwater Overexploitation in Shan County

摘要:

单县水资源极其匮乏,地下水为当地重要的供水水源,浅层淡水埋藏浅易补源,深层承压水埋藏较深不易回补属限制开采区。通过超采综合治理,减少了地下水开采量,实现了地下水位逐步回升,对保障非常时期用水和应急供水,具有极其重要的现实意义。本文介绍了单县水资源利用现状和超采现状,重点阐述了单县“先建机制、后建工程”的“双行”模式治理,提出了超采存在的问题,给出了合理的对策建议,可为同类平原超采地区治理提供参考。

Abstract:

The water resources in Shan County are extremely scarce, and groundwater is an important water supply source locally. The shallow fresh water has a shallow burial depth and is easy to be replenished, while the deep confined water has a relatively deep burial depth and is hard to be recharged, belonging to the restricted exploitation area. Through the comprehensive treatment of overexploitation, the groundwater extraction volume has been reduced, and the gradual rise of the groundwater level has been realized, which has extremely important practical significance for ensuring water use during extraordinary periods and emergency water supply. This paper introduces the current situation of water resources utilization and overexploitation in Shan County, focuses on elaborating the "dual-line" mode treatment with the principle of "establishing the mechanism first and then the project execution", puts forward the existing problems of overexploitation, and gives reasonable countermeasures and suggestions, which can provide reference for the treatment of similar plain areas with overexploitation.
