晋祠岩溶泉流量衰竭分析

Analysis of the Reduction in Flow from Jinci Springs

根据晋祠泉域41年的补径排资料,对晋祠泉流量的衰减进行了综合分析,得出了导致晋祠泉断流的因素有:大气降水量、汾河渗漏量、人工开采量(含采煤排水)、太原盆地孔隙水开采量等,其中人工开采岩溶水(含采煤排水)是引起泉流量衰减的最主要因素。

Based on Jinci spring area information of the recharge, flow, and discharge of groundwater, the attenuation of Jinci spring was analyzed. It was concluded that the factors, such as precipitation, leakage of the Fenhe, the exploitation of karstic groundwater as well as coalmines discharge, and the exploitation of groundwater in Taiyuan basin, affected the flow of Jinci spring. The water discharge from coalmine and groundwater overexploitation are the essential factors in the attenuation.
