摘　　要：土地利用变化对水文的影响已引起社会的广泛关注。以东辽河流域为研究对象,以分布式水文模型SWAT和土地利用变化模型CLUE-S为研究工具,通过将SWAT与CLUE-S模型耦合,定量评估了东辽河流域未来2种不同情景模式下的土地利用变化对流域水文过程长期的影响。研究结果表明:2016—2025年情景1的平均径流量为15.41m3/s,2016—2025年情景2的平均径流量为13.8m3/s,2025年情景2的土地利用变化比情景1的土地利用变化更有利于减少径流的流失;通过对比分析2000—2025年不同情景模式下土地利用变化的植被覆盖率变化,2000年植被覆盖率由77.51%变化到2025年情景1的77.23%和2025年情景2的78.93%,表明植被覆盖率与径流的流失量呈反比。因此,研究区未来土地利用变化应按照国家土地利用规划实行,对东辽河流域水资源规划及可持续发展具有重要的意义。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 1from 2016 to 2025will be 15.41m3/s and the runoff in scenario 2from 2016 to 2025will be 13.80m3/s,the result shows that the land use change in scenario 2will 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 1of 2025,and the vegetation coverage will change from 77.51%to 78.93%from 2000 to the scenario 2of 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.
