The China-Mongolia railway, which connects China and Mongolia, is the main cross-border traffic trunk line in China-Mongolia-Russia region and the core foundation of the transportation connection in the construction of the China-Mongolia-Russia economic corridor in the "Belt and Road". The China-Mongolia-Russia economic corridor is characterized by complex natural geography, fragile ecological environment, frequent natural disasters, and serious desertification. By collecting the basic geographical and zoning data, land cover data, and mechanism analysis of vegetation coverage index and different feature space mode, this application discussed the relationship between the inversion model of desertification and land cover and vegetation, and judges the applicable conditions of different models. We obtained the distribution data of desertification along the China-Mongolia railway (Mongolia section) in 2000, 2010 and 2015 with a resolution of 30 meters, and implemented the map visualization application at the front end using the fine print JavaScript library. The application of this knowledge was collected and organized by the Institute of Geographic Sciences and Natural Resources Research, CAS. It has realized the sorting and archiving of the desertification data along the China-Mongolia railway (Mongolia section), completed the analysis of the distribution pattern of desertification in this region, grasped the overall spatial law of the desertification region, and determined the key desertification areas. It can then be used in the research of desertification risk assessment along the China-Mongolia railway (Mongolia section), providing fine and continuous data product support for the prevention and control of desertification ecological risk along the China-Mongolia railway (Mongolia section), and escorting the green and sustainable development of the China-Mongolia-Russia economic corridor.
