A dataset of 1km-grid comprehensive indexes of land use degree density in China(2020)
The comprehensive index of land use degree quantitatively reflects the development and use degree of the ecological environment by human activities from the aspect of land use.The dataset is derived from the 30-meter land use raster data produced based on the 2020 national land change survey data.We used the land use comprehensive index model to quantitatively analyze the national land use degree evaluation by dividing the land use into four degrees:unused land,the land used for forestry,meadow and waters,agricultural land,and urban settlement land.We comprehensively calculated the degree of human intervention in regional land use.In order to ensure data correctness and accuracy,we adopted unified and standardized data processing methods,sample collection rules,and quality control systems to control the quality of the data results.This dataset can be used for a valuable reference for the research on territorial spatial planning,regional development and development evaluation,main body functional area evaluation,and coupling analysis of human-land relations.
