2024-06-25 A dataset of 1km Grid Comprehensive index of land use degree Density in China(2020） doi:10.57760/sciencedb.05156 en Comprehensive index of land use degree quantitatively reflects the degree of exploitation and utilization of ecological environment by human activities from the aspect of land use, and is an important index to measure the depth and breadth of regional land use. The data set of comprehensive degree index of land use of 1km grid in China in 2020 is based on the 30-meter grid data of the national change survey in 2020. Considering the influence of social factors, the land use is divided into four levels: unused land, forest, grass and water land, agricultural land and urban settlement land. The degree of human intervention in regional land use is comprehensively calculated to quantitatively reflect the degree of land use in the study area. Meanwhile, in order to ensure the correctness and accuracy of the data, unified and standardized data processing methods, sample collection rules and quality are adopted. This data set can be used for land space planning, regional development and development evaluation, main functional area evaluation, coupling analysis of human-land relationship, etc. Comprehensive index of land use degree; land survey; grid; grading index; China Zhang Xiaotong zhang ding xiang Wang Xiulian Peng Jinfu Li Yanan Li Shijiang PUBLIC https://creativecommons.org/licenses/by-nc-sa/4.0/ dataset http://www.doi.org/10.11922/11-6035.csd.2022.0100.zh Science Data Bank
