Spatial Distribution of 1‑km Grid Saline‑Alkali Land in China (2024)
Listed in ScienceDB
According to the Land Classification for National Land Survey (GB/T 21010-2017), saline alkali land refers to land where surface salt alkali accumulates and natural salt tolerant plants grow, as well as uncultivated wasteland.
Description
This dataset utilizes the results of the 2024 annual change survey, which have been gridded and managed for grid production. Grid storage is used, with data values ranging from 0 to 1, representing the fraction of saline alkali land area within 1 square kilometer.
This dataset can be used for saline alkali land management, assessment of reserve resources for arable land development, etc.
