超采区关井压采地下水环境修复评价体系初探

Study on the Groundwater Environment Rehabilitation Effect Evaluation System of Closing Wells and Reducing Groundwater Exploitation in Groundwater Overexploitation Area

以地下水开采量变化、地下水水位回升、泉流量变化、地面沉降速率、地裂缝增长、河岸植被恢复以及有关生态环境质量状况共7个影响因子,构建了关井压采地下水环境修复效果评价体系,并给出了相应的指标分级、标准及评价方法。以太原市地下水超采区为例,对2003年以来关井压采对地下水环境修复效果进行了评价。

Taking groundwater exploitation quantity variation, groundwater level variation, spring flow variation, ground subsidence rate, ground crack growth, riparian vegetation restoration and ecological environment quality as impact factors, this paper established groundwater environment re- habilitation effect evaluation system of closing wells and reducing groundwater exploitation. And the corresponding index classification, index selec- tion criteria and evaluation method were given. Meanwhile, taking the groundwater overexploitation area in Taiyuan city as an example,this paper evaluated the groundwater environment restoration effect of elosing wells and reducing groundwater exploitation since 2003.
