摘要：

In order to study the spatial distribution and temporal variation of land desertification in the four counties of Bashang, Zhangjiakou, Hebei, a total of two time-phases of Landsat-8 remote sensing data in 2017 and 2018 were used as data sources, taking Normalized Vegetation Index (NDVI) as the main quantitative remote sensing interpretation method to derive the patterns of land desertification changes in the four counties of Bashang, Zhangjiakou, Hebei in recent years. The results showed that from 2017 to 2021, the chang of lightly and moderately desertified land areas in the four counties of Bashang, Hebei were generally stable, the areas of heavy and extremely desertified land decreased significantly, the condition of overall land desertification has improved significantly.
