Abstract

In order to analyze the changes of desertification in Mongolia border region, this paper took the Dongwuzhumuqin and Halahahe as the research area, based on 2000-2015 years Vegetation growth season MODIS NDVI data, the vegetation coverage was calculated by using pixel two model, desertification index (DI) was obtained, and the areas of different types of desertification were calculated based on pixel scale. Moreover, the correlation between desertification areas and social with the number of large animals. The process of halahahe desertification is not significantly reversed and developed, and the not desertification land area increased significantly, mild and severe desertification land area was significantly reduced, reduction of moderate desertification area, and the extreme desertification area is increased, but the trend is not significant. The area of desertification land is distributed in the west and the northwest region.2000-2014 years, there was a significant correlation between the Halahahe land area and population quantity of the not desertification and the mild desertification. economic data was analyzed to obtain the dynamic change of desertification of Mongolia border region in recent 15 years. The result indicated that Dongwuzhumuqin desertification has been reversed-development-reversed process, the area of not desertification mild moderate and severe desertification was increasing, and the area of extreme desertification land is declining, but the trend is not significant.2000-2014 years Dongwuzhumuqin the extreme desertification land area was significantly correlated with the population quantity, severe and extreme desertification land was significantly correlated with the number of large animals. The process of halahahe desertification is not significantly reversed and developed, and the not desertification land area increased significantly, mild and severe desertification land area was significantly reduced, reduction of moderate desertification area, and the extreme desertification area is increased, but the trend is not significant. The area of desertification land is distributed in the west and the northwest region.2000-2014 years, there was a significant correlation between the Halahahe land area and population quantity of the not desertification and the mild desertification.
