近年来,地下水已成为北京市的重要供水水源,为合理开发利用和有效保护地下水资源,参照水利部编发的《全国地下水功能区划分技术大纲》的要求进行了北京市地下水功能区划分。将北京市划分为3种地下水一级功能区和7种地下水二级功能区,共62个二级分区。 In recent years, groundwater has become an important source of water supply for Beijing. In order to rationally develop and utilize groundwater resources and effectively protect the groundwater resources, the groundwater functional zoning of Beijing was conducted in accordance with the “Technical Outline for the Division of Groundwater Functional Zones” compiled by the Ministry of Water Resources. The city of Beijing is divided into three kinds of groundwater functional areas and seven groundwater secondary functional areas, a total of 62 secondary partitions.
