济南市羊里水源地保护区划分方法探讨

Discussion on the division method of yangli water source protection area in jinan

济南市莱芜区供水以地下水为主,近年来,随着经济的快速发展,水资源需求日益增长,区域地下水过量开采,形成大面积地下水漏斗区,加之工业和生活污水的无序排放,造成水质轻微污染。以济南市莱芜区羊里地下水水源地为研究对象,结合水源上游及周边污染源分布、水文水质和地形地貌特征,在分析羊里水源地地下水系统及水资源特征的基础上,依据《饮用水水源保护区划分技术规范》(HJ 338-2018)对水源地保护区进行划分,运用经验值方法并结合地形地质条件进行修正,保护水源地免受污染,以期为羊里地下水资源的健康长效发展提供参考。

In recent years,with the rapid development of economy,the demand for water resources is growing day by day.The excessive exploitation of regional groundwater forms a large area of groundwater funnel area.In addition,the disordered discharge of industrial and domestic sewage results in slight pollution of water quality.Taking Yangli groundwater source area in Laiwu District of Jinan City as the research object,combined with the distribution of pollution sources in the upstream and surrounding areas of the water source,the characteristics of hydrology,water quality,topography and geomorphology,based on the analysis of the characteristics of groundwater system and water resources in Yangli water source area,according to the technical code for the division of drinking water source protection area( HJ 338-2018),the water source area protection area is divided,and the empirical value method is used to combine In order to provide a reference for the healthy and long-term development of groundwater resources in Yangli,the geological conditions should be corrected to protect the water source from pollution.
