Abstract

This paper uses the Xilin Gol League as a research area, based on Landsat TM and meteorological data for the past 15 years, selects three periods of remote sensing images to use RS, GIS technology and dynamic degree and landscape index to select the landscape pattern and desertification dynamics of sandy land from 2000 to 2015. The driving force factor is analyzed. The results show that the degree of fragmentation of the sandy landscape in the Xilin Gol district was reduced from 2000 to 2015, the landscape patch area was regularized, and the disturbance intensity of human activities on sandy land was reduced; the degree of desertification generally showed a reversal trend, but there was a development trend during the period. Further research shows that from 2000 to 2015, the main factors affecting the reversal of desertification are the increase of precipitation and the implementation of national and local policies in order to provide a theoretical basis for the desertification control project of the motherland and the protection of ecological security in the Beijing-Tianjin-Hebei region.
