长三角1：100万湖泊分布数据集（1960s-1980s）

该数据集为长三角三省一市空间区域100万湖泊分布数据。该数据集在长三角1960s至1980s多幅地形图基础上，先对地形图进行几何校正，再地形图基础上，对湖泊边界进行人工提取，并结合资料对湖泊名称、面积、所属流域、空间位置等属性进行补充完善，得到研究区的湖泊分布数据。
数据集包含1个shp矢量数据，slhp.shp

This dataset is a 1:1,000,000-scale lake distribution dataset for the spatial scope of the Yangtze River Delta (three provinces and one municipality directly under the Central Government). It was developed based on multiple topographic maps of the Yangtze River Delta from the 1960s to the 1980s. First, geometric correction was performed on these topographic maps. Next, lake boundaries were manually extracted from the corrected maps. Furthermore, attributes including lake names, areas, affiliated drainage basins, and spatial locations were supplemented and refined using relevant reference data, ultimately yielding the lake distribution dataset for the study area. The dataset contains one shapefile vector data file named slhp.shp.
