title: Soil Resource Dataset of Urban Land Occupation in Changji Economic Zone, Jilin Province (2000)
title: 吉林省长吉经济区城镇用地占用土壤资源数据集（2000年）

description: a. Data content (data file/table name, including observation indicators)
This data includes land use data of Changji Economic Zone in 2000 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
2000
e. The spatial scope of data
Changchun City, Jiutai District, Jilin City, Yongji County, Shuangyang District, Jilin Province
f. Projection method of data
Projected Coordinate System：Krasovsky_1940_Albers
Geographic Coordinate System：GCS_Krasovsky_1940
g. The disciplinary scope of data
Geography and Ecology
h. Quantity of data
The total data volume is about 12.2MB
