太原市西山岩溶区汾河与地下水相互作用研究

通过对汾河西山岩溶区段的河道下垫面背景分析,将汾河干流汾河水库至兰村区间分为7个区段,识别出了4个汾河与岩溶地下水相互作用积极的地段。以地下水系统理论为指导,将兰村泉和晋祠泉岩溶水系统概化为双输入(大气降水与人工开采)单输出(泉流量)模型,在此基础上,基于岩溶水天然资源量与大气降雨入渗量、河流渗漏量关系推算出了汾河与各岩溶水系统岩溶地下水的作用强度,即汾河对各岩溶水系统的渗漏补给量。研究成果对于指导太原市水资源综合利用,缓解太原市水资源供需矛盾,有效保护岩溶地下水等提供了科学参考依据。

Study on Fenhe River and Groundwater Interaction in Xishan Karst Region of Taiyuan City

By analysis of riverbed of Fenhe River Xishan karst section,the waterway of Fenhe River from Fenhe River reservoir to Lancun was divided into 7 sections,of which 4 sections were recognized as active interaction sections of Fenhe River and karst groundwater.Guided by groundwater system theory,this paper established double input(rainfall and exploitation) and single output(flow rate of spring) model for Lancun spring and Jinci spring karst water systems.On the relationship among natural resources amounts of k...
