为了研究径流对土地利用极端变化的响应，利用土壤和水评估工具（SWAT）模型构建了中国东北多年冻土区几种主要景观类型的历史、极端和未来情景。结果表明：SWAT模型适用于塔河流域，流域内主要土地利用类型为林地、灌丛、湿地和草地，1980-2015年各土地利用类型间的转移对径流的影响小于5%。在极端的土地利用变化情景下，模拟的径流量从草地到湿地，灌木丛，最后，林地减少。极端土地利用情景的转换产生不同的水文效应。林地转化为草地后，径流量增加25.32%，林地转化为湿地后，径流量增加13.34%，灌木林转化为林地后，径流量减少13.25%。此外，径流对不同土地利用变化的敏感性在汛期比在旱季大得多。与2015年参考年相比，未来两种土地利用情景（灌丛-林地和灌丛-湿地）下的模拟年径流量均偏少，且均表现出减少洪涝和增加干旱的效果，为塔河流域和东北多年冻土区土地利用与水资源的综合管理提供了重要参考。
To study the response of runoff to extreme changes in land use, the Soil and Water Assessment Tool (SWAT) model was used to construct historical, extreme, and future scenarios for several major landscape types in a permafrost region of northeastern China. The results show that the SWAT model is applicable in the Tahe River Basin; forestlands, shrublands, wetlands, and grasslands are the main land-use types in this basin, and the transfers among them from 1980–2015 have impacted runoff by less than 5%. Under extreme land use-change scenarios, the simulated runoff decreased from grasslands, to wetlands, shrublands, and finally, forestlands. The conversion of extreme land-use scenarios produces different hydrological effects. When forestland is converted to grassland, runoff increases by 25.32%, when forestland is converted to wetland, runoff increases by 13.34%, and the conversion of shrubland to forestland reduces runoff by 13.25%. In addition, the sensitivity of runoff to different land-use changes was much greater during flood seasons than in dry seasons. Compared to the reference year of 2015, the annual simulated runoff under the two future land-use scenarios (shrublands to forestlands and shrublands to wetland) was less. Also, both future land-use scenarios showed effects to decrease flooding and increased dryness, This study provided important insight into the integrated management of land use and water resources in the Tahe River Basin and the permafrost region of northeastern China.
