AB  - This dataset records the GDP data of the Chaohu Lake Basin, Chu River Basin, Lishiahe River area and the Yangtze River Delta Demonstration Area at three important time nodes, 2000, 2010 and 2020, and adopts the high-precision remote sensing analysis technology with a spatial resolution of 12.5 meters, which is finely divided into elevation bands, aiming to reveal the impacts of different topographic heights on the distribution of economic activities and their trends over time. The data are finely divided into elevation bands, aiming to reveal the effects of different terrain heights on the distribution of economic activities and their trends over time. The dataset is able to visualize the absolute growth of the total economic volume in each elevation zone, and also provides insight into the relative transfer and agglomeration of economic activities among different elevation zones. By comparing the data at three time points, the dataset clearly depicts the spatial and temporal evolution characteristics of GDP with elevation changes in each watershed and demonstration area. These features not only reflect the constraining and promoting effects of topographic conditions on economic development, but also reveal the adjustment and optimization process of regional economic structure. This dataset provides rich and detailed data support for the in-depth study of the relationship between economic development and topographic elevation in the Chaohu Lake Basin, the Chu River Basin, the Lishiahe River Region and the Yangtze River Delta Demonstration Area, and is of great value in the fields of regional economic planning, policy making, and sustainable development research.
