鄱阳湖流域1:100万基础地理数据集（2015-2019年）

该数据集在全国1:100万基础地理数据的基础上，提取鄱阳湖流域范围内的省市县政区、湖泊水系、居民地、交通等图层数据，构成太湖流域1:100万基础地理数据集。
数据集按年分类存放，每年包含9个shp矢量图层数据，“BOUA_prov.shp”：省级行政区；“BOUA_city.shp”：地级市行政区、；“BOUA_district.shp”：县级行政区；“HYDA.shp”：面状水系数据；“HYDL.shp”：线状水系数据；“LRRL.shp”：铁路数据；“RESA.shp”：居民地数据；“RESP.shp”:居民点数据；“LRDL.shp”：公路数据。

This dataset is derived from the national 1:1,000,000 scale fundamental geographic data, by extracting thematic layers including provincial, prefecture-level and county-level administrative divisions, lake water systems, settlements, transportation and other relevant categories within the Poyang Lake Basin, to form the 1:1,000,000 scale fundamental geographic dataset for the Taihu Lake Basin. The dataset is stored in yearly categorized directories, with 9 shapefile (shp) vector layer files included for each annual dataset. The detailed descriptions of each layer are as follows: "BOUA_prov.shp": provincial administrative divisions; "BOUA_city.shp": prefecture-level city administrative divisions; "BOUA_district.shp": county-level administrative divisions; "HYDA.shp": areal water system data; "HYDL.shp": linear water system data; "LRRL.shp": railway data; "RESA.shp": settlement data; "RESP.shp": residential spot data; "LRDL.shp": highway data.
