黄河流域1：25万湖泊分布数据集（1970-2020年）

该数据集为黄河流域1：25万湖泊分布数据集（1970-2020年）。结合Landsat影像、地形图，利用半自动水体提取及人工目视检查编辑，完成了详细的中国湖泊(大于1平方公里)数量与面积变化研究，根据一级流域黄河流域边界数据对数据进行裁切处理后，得到该数据集。包括了湖泊面积、使用的数据、日期等指标。
该数据集包含8个数据集，分别包含1个shp矢量数据，分别为lake1970.shp，lake1990.shp，lake1995.shp，lake2000.shp，lake2005.shp，lake2010.shp，lake2015.shp，lake2020.shp。

This dataset is the 1:250,000 scale lake distribution dataset of the Yellow River Basin (1970-2020). It was generated by clipping the results of a detailed study on the quantity and area changes of lakes in China (with an area ≥1 km²) using Landsat imagery and topographic maps, via semi-automated water body extraction combined with manual visual inspection and editing, based on the boundary data of the first-level watershed—the Yellow River Basin. The dataset includes indicators such as lake area, used data sources, and acquisition dates. This dataset package contains 8 sub-datasets, each consisting of a single shapefile (SHP) vector data, specifically lake1970.shp, lake1990.shp, lake1995.shp, lake2000.shp, lake2005.shp, lake2010.shp, lake2015.shp, and lake2020.shp.
