title: Spatial temporal dynamic data set of land desertification at 30m resolution in Tongyu County, Jilin Province (1990)
title: 吉林省通榆县30m 分辨率土地沙漠化时空动态数据集（1990年）

description: a. Data content (data file/table name, observation index content included)
This data includes the spatial-temporal dynamic data set of land desertification with a resolution of 30m in Tongyu County, Jilin Province in 1990, which reflects the dynamic changes of land desertification in Tongyu County, and is of great significance to the prevention and control of desertification, the improvement of ecological environment, the promotion of regional coordinated development, and the realization of harmonious development between man and nature.
b. Construction purpose
Tongyu County, as a key county of the national poverty alleviation and development work, has a single industrial structure and rich cultivated land resources. However, it is located in the area with serious desertification in the west of Jilin Province, and its ecology is fragile. The problem of land desertification directly affects the quality of local cultivated land and grassland, and seriously restricts its agricultural development and ecological security. A detailed and in-depth analysis of the process of land desertification in Tongyu County in 1990 is of great significance to the prevention and control of desertification, the improvement of ecological environment and the promotion of regional coordinated development.
c. Service object
It can be widely used for scientific researchers in ecological protection, desertification prevention and control and other related disciplines.
d. Time range of data
1990
e. Spatial range of data
Tongyu County, Jilin Province
f. Projection mode of data
Projected Coordinate System：Krasovsky_1940_Albers
Geographic Coordinate System：GCS_Krasovsky_1940
g. Subject scope of data
