A dataset of 1km Grid Land Development Intensity in China（2020）

The intensity of land development is an intuitive reflection of the degree of regional land use, and a comprehensive reflection of the degree of regional land development and its cumulative carrying density. This dataset adopts the grid based results of the 2020 National Land Change Survey of China (excluding Hong Kong, Macao, and Taiwan) for 30 meters of land use, and uses kilometer grid software to calculate all land types involved in construction land classification, forming a national 1km grid land development intensity dataset. In order to ensure the correctness and accuracy of data, a unified and standardized data processing method, sample collection rules, and quality control system are adopted to control the quality of data results. This dataset can be used for national spatial planning, planning implementation evaluation, urban health examination, and policy implementation evaluation of main functional areas.
