摘要
在系统分析、整理研究区20多年来地下水水位和水质资料的基础上,研究了人类强烈活动影响下的地下水水位、水质的时空演化规律;分析了大同市在人类活动影响下的地下水环境演化规律;认为日益增强的人类活动是影响城市地下水资源短缺和水质恶化的重要因素;探讨了大同市水文地球化学的分带性,即把研究区分为地下水补给区(未受影响带)、地下水径流区(工业活动影响带)以及地下水排泄区(农业活动影响带)。这些研究可为大同市地下水政策的制定和实施提供科学的理论依据。
Groundwater is the unique water resource for water supply and industrialagricultural activities.However,the levels of shallow Quaternary groundwaters in Datong City have been declining continuously and groundwater quality deteriorating because of longtime overexploitation of the groundwater resource,which results in a series of water resourceenvironment problems.These problems have,in turn,seriously restrained sustainable development of societyeconomy.In this paper,the spatial and temporal evolution of groundwater level and quality and shallow groundwater environment evolution influenced by intensive human activities have been studied based on groundwater levels and water quality data since 1981.The study indicates that increasingly enhanced human activity is the key for groundwater shortage and deterioration.In addition,zonation of hydrogeochemistry has been discussed.
