2024-11-15 Soil Resource Dataset of Urban Land Occupation in Changji Economic Zone, Jilin Province (2015) doi:10.57760/sciencedb.iga.00983 en a. Data content (data file/table name, including observation indicators) This data includes the land use data of Changji Economic Zone in 2015 with a resolution of 30 meters, reflecting the impact of urbanization on soil resources, which is of great significance for coordinating regional development and ensuring soil multifunctionality. b. Construction purpose Changchun Jilin Economic Zone is one of the fastest urbanized areas in Northeast China, as well as a famous black soil region and an important commodity grain base in China. In recent years, especially after the implementation of the "Northeast Revitalization" policy, the economy of the development zone has achieved unprecedented development. The expansion speed of urban land is accelerating, and the soil sealing area has significantly increased. Soil sealing has become a serious threat to the environment, food supply, and safety. Therefore, monitoring the soil sealing process caused by urbanization and the impact of urbanization on soil resources is of great significance. c. Service target It can widely serve scientific researchers in related disciplines such as ecological monitoring, urbanization, and soil quality assessment. d. Time range of data 2015 e. The spatial scope of data Changchun City, Jiutai District, Jilin City, Yongji County, Shuangyang District, Jilin Province f.
