The land use data of 30m in Jinghe River basin includes 8 first-class categories: cultivated land, forest, grassland, shrub land, wetland, water body, artificial surface and bare land. It contains rich information about the spatial distribution of land cover, which can better describe the land use status and spatial distribution.

The classified images of the data set mainly use 30m multispectral images (Landsat series multispectral images) and 16m resolution multispectral images of gaogao-1 (GF-1) WFV sensor. The cloud amount controls the remote sensing image when the cloud amount allows. It is divided into eight first-class categories, namely cultivated land (code 10), forest land (code 20), grassland (code 30), shrub land (code 40), wetland (code 50), water body (code 60), artificial surface (code 80) and bare land (code 90).
Taking the Jinghe River Basin as the research area, the land use data with spatial resolution of 30m in 2000, 2010 and 2020 were extracted by mask.
The overall accuracy of land use data in 2000, 2010 and 2020 is more than 85%, and the kappa coefficient is more than 0.85.
Good data quality.
