山西省山阴县地下水特征及其土壤盐渍化现状研究

Research on Groundwater Characteristics and Its present situation of Soil Salinization in Shanyin County of Shanxi Province

通过研究山阴县北部洪涛山前倾斜平原与冲积平原的水文地质特征,以及不同水文地质单元浅层地下水的水文地球化学特征,分析了TDS、总硬度和SO_4^(2-)的变化趋势及其形成原因,最后针对地下水环境对土壤盐渍化的影响机理,提出土壤渍化防治及改造过程中应注意的问题,可通过减少灌水入渗量,加大灌区潜水排泄量等盐防治措施进行盐碱地治理。

By the research on the hydrogeological characteristics of piedmont inclined plain and alluvial plain in Hongtao mountain,the northern region of Shanyin County,and the hydrogeochemical characteristics of shallow groundwater in different geohydrologic units,this paper analyzed the change trends and the forming reasons of TDS,total hardness and SO_4^2- along the process of groundwater. Finally,based on the groundwater environment impact factors of soil salinization,this paper putted forward the prevention measures and Suggestions.
