%X This dataset focuses on the changes of surface imperviousness in the Chaohu Lake Basin, Chu River Basin, Lishiahe River Area and the Yangtze River Delta Demonstration Area at three key time points, namely, 2000, 2010 and 2020, and adopts high-precision remote sensing technology with a spatial resolution of 12.5 meters to carry out a detailed dynamic monitoring and detailed interpretation of the imperviousness properties of the surface in the Demonstration Area. The dataset not only provides the statistical results of the average imperviousness of the watersheds and the demonstration area in different time periods, but also reveals the spatial and temporal characteristics of the imperviousness of the subsurface (i.e., the surface cover) through the comparative analysis of the time series. This information is essential for understanding the hydrologic cycle process in the watersheds and for assessing the risk of flooding and the storage and drainage capacity.
