30m resolution saline alkali bare land distribution dataset in the black soil area of Northeast China (1990)

Data content (data file/table name, including observation indicators) This data includes a 30m resolution saline alkali bare land distribution dataset in the black soil area of Northeast China, which reflects the distribution of saline alkali bare land in the black soil area of Northeast China and provides data support for black soil protection, soil remediation, land planning, and other aspects. b. Construction purpose Black soil is a precious resource bestowed upon humanity by nature, and the black soil region in Northeast China has become a "stabilizer" and "ballast" for food production.

By understanding the distribution of saline alkali bare land in the black soil region of Northeast China, data support can be provided for the "proper use and cultivation" of black soil. c. Service target It can widely serve scientific researchers in related disciplines such as black soil protection and ecological monitoring. d. Time range of data 1990 e.
