- Abstract:
- The influence of land use change on hydrology has obtained the extensive concern of society. Dongliaohe Basin was chosen as the case study area. Used distributed watershed hydrological model SWAT (Soil and Water Assessment Tool) and CLUE-S model, we modeled the hydrological response to different land-use change scenarios through coupling the models for SWAT and CLUE-S. The result shows that the runoff in scenario 1 from 2016 to 2025 will be 15.41 m3/s and the runoff in scenario 2 from 2016 to 2025 will be 13.80 m3/s, the result shows that the land use change in scenario 2 will be better for runoff reduction; through comparisons of land use change of vegetation coverage from 2000 to 2025, the vegetation coverage will change from 77.51% to 77.23% from 2000 to the scenario 1 of 2025, and the vegetation coverage will change from 77.51% to 78.93% from 2000 to the scenario 2 of 2025, which shows that the vegetation coverage has the negative relationship with runoff. Therefore, the future land use change in the study area should be in accordance with the national land use planning, the Dongliaohe Basin resources planning and sustainable development have the vital significance.
