A dataset of desertification degree monitoring in Inner Mongolia from 2001 to 2021

Abstract

Located in China's Inner Mongolia Plateau, Inner Mongolia Autonomous Region is the main area of the Mongolian Plateau in China, and it is also a key research area for desertification and sandification monitoring. The land in this area is severely desertified and sandificated. Carrying out annual monitoring according to the characteristics of desertification land in this region is a necessary support for the research on grasping the dynamic characteristics of desertification and comprehensively analyzing the causes of desertification. We based the monitoring research on the MODIS data from 2001 to 2021 in the Inner Mongolia Autonomous Region and selected FVC, MSAVI, LST, TVDI indicator to generate indicator discriminant values through information overlay analysis, classification, and discrimination. And according to the zoning regulations, we obtained the annual monitoring data of desertification degree from 2001 to 2021 in 4 climate zones in Inner Mongolia. This dataset can provide data support for studies on desertification changes and driving mechanisms and so on.
