AB  - This dataset comprehensively covers the distribution of population density in the Chaohu Lake Basin, the Chu River Basin, the Lishiahe River area and the Yangtze River Delta Demonstration Area at three key time points, 2000, 2010 and 2020, with refined statistics and analysis by elevation bands. Adopting high-precision remote sensing analysis technology with 12.5-meter spatial resolution, the dataset provides detailed statistics on the number of people within each elevation band and the population of the whole basin. The elevation band delineation method provides a deeper understanding of the complex relationship between population distribution and topographic features, and how this relationship evolves over time. It is of great significance for assessing the impact of topographic conditions on human settlement choices, predicting future population distribution patterns, and formulating targeted regional development plans. In addition, by comparing the data at the three time points, the dataset also demonstrates the dynamic change characteristics of population distribution over time, providing researchers with valuable time series data support. These changing features not only reflect the changes in socio-economic conditions, but also imply the influence of the natural environment on the spatial distribution of human activities. This dataset provides a detailed data base for understanding the distribution of population density and its relationship with topographic elevation in the Chaohu Lake Basin, the Chu River Basin, the Lishiahe River area and the Yangtze River Delta Demonstration Area, and it is of great value for research and practice in the fields of regional planning, population management and environmental protection.
