Abstract:

To reveal the spatio-temporal changes of land use pattern in China in the early 21st century, based on the global 30 m land cover remote sensing data product (GlobeLand30), using the qualitative and quantitative analysis methods, we analyzed the land use transfer matrix and land use dynamics in the 10 years. The results showed that: grassland, forest and cultivated land were the main land use types in the study area, and the areas of grassland, cultivated land and wetland decreased continuously by 140413, 20480 and 692 km 2, respectively; the areas of bare land and artificial land increased obviously by 99645 and 26302 km 2; the transformation between grassland and bare land, grassland and forest was more intense; shrub land and artificial land surface had the largest change rate, reaching 1.80%; the patterns of land use types in each sub-basin were different, and grassland, cultivated land and forest were the main types in most basins. The types of grassland, bare land and artificial land surface change obviously in the region, the influence of human factors on land use pattern is great and active, and the influence of natural factors is lasting and stable.
