Objective  In order to provide a reasonable basis for land use planning and promote the sustainable development of the basin, the characteristics of land use change in Chishui River Basin had been analyzed in recent ten years, in order to explore the spatial allocation of water resources and hydrological cycle process under the background of ecological civilization construction.

  Method  Under the climate background of 1967-2020, based on the SWAT (Soil and Water Assessment Tool) model, the surface runoff, underground runoff and total runoff of the Chishui River Basin were simulated from 2008 to 2020, thereby the variation characteristics and responses to land use/cover change of them were analyzed.

  Result  The results showed that (1) the R² and NSE of the three stations were greater than 0.6, and the SWAT model was suitable for the hydrological process simulation of Chishui River Basin; (2) The basin was dominated by cultivated land, forest land and grassland. During the study period, the area of cultivated land, forest land and grassland decreased by 47.57 km², 23.51 km² and 4.75 km², respectively. While the area of water area and construction land increased by 9.42 km² and 65.98 km², respectively; (3) Under the background of 4 stage land uses, the surface runoff and total runoff showed a fluctuating upward trend, while the underground runoff showed a fluctuating downward trend, and the surface runoff was more sensitive to land use / cover change than the underground runoff; (4) The surface runoff order was construction land > cultivated land > forest land > grassland, while the underground runoff order was forest land > grassland > cultivated land > construction land, and the total runoff order was cultivated land > construction land > forest land > grassland.

  Conclusion  On the whole, the effect of river closure and water storage was forest land > grassland > cultivated land > construction land, and forest grassland had better function of river closure and water storage.
