南京市城区1:25万环境水文地质数据(1989年)

该数据集为南京市城区环境水文地质空间分布数据，数据范围为南京市，时间为1989年。通过对南京市城区环境水文地质图进行配准数字化并结合在线地图进行数据更新得到南京市城区环境水文地质空间分布位置，数据主要包括南京主城区内地下水类型、自流水分布、古河道、污染物范围以及地表水供水量。数据以ESRI SHAPEFILE格式存储。

This dataset presents spatial distribution data of environmental hydrogeology in the urban area of Nanjing, with a spatial coverage of the entire city of Nanjing and a temporal scope of 1989. The spatial distribution locations of environmental hydrogeology in Nanjing's urban area were derived through the registration and digitization of the urban environmental hydrogeology map of Nanjing, combined with data updates using online maps. The data primarily covers groundwater types, artesian water distribution, ancient river channels, pollutant extents, and surface water supply volumes within the main urban area of Nanjing. All data is stored in ESRI SHAPEFILE format.
