The terrain slope constrained map is a global raster data layer with a resolution of 5 arc minutes. Each pixel contains a category value that represents the degree to which the terrain slope restricts the agricultural production potential of the pixel area. Obtain terrain slope limit data for the Heilongjiang River Basin through clipping. The data is sourced from the Food and Agriculture Organization and IIASA（ https://data.apps.fao.org/map/catalog/srv/eng/catalog.search#/metadata/a90f59a0 -7a41-11db-b9b2-000d939bc5d8), spatial coordinate system WGS 84
