鹰手营子矿区地下水水质的农业影响分析

Analysis of agricultural impact of groundwater quality in the Yingshouyingzi mining area

在对河北省承德市鹰手营子矿区地下水进行水环境质量评价的基础上,着重开展矿区饮用水质的影响因素调查。内梅罗指数法的评价结果显示,该矿区4处水井的水质均属于Ⅲ类水,但各水井水质差异较显著。通过调查矿区的土地利用情况、生活污水和农田径流状况发现,矿区水源地保护区内及其周边分布有大量居民和农田,生活污水和农业施肥严重影响了饮用水质,是造成该矿区水环境恶化的重要因素。

This study paied more attention to the survey on the interfering factors about the groundwater on the basis of environmental impact assessment in the Yingshouyingzi mining area,Chengde city,Hebei province.The Nimero index method’s result displayed that the quality type of four wells in this mining area belonged to the third estate,however,the water quality was different among four wells.Through the survey of land use,domestic sewage and agricultural runoff,it founded that there were many residents and farmlands around the reserves,domestic the sewage and the agricultural fertilizer had seriously affected the quality of drinking-groundwater,which was the most important influencing factor that caused the deterioration of water environment.
