摘　　要：西南高山峡谷区覆盖大横断“七脉六江”地区,是国家“三区四带”重要生态安全屏障,对保障国家生态安全和区域高质量发展具有重要作用。针对西南高山峡谷区存在的水土流失分异演变地带性规律及其关键驱动机制,水土流失对农业耕作、高陡地形、岩溶地质及冻融作用等复杂驱动条件的响应及其防控机制,民族聚集区生态系统服务功能整体提升及生态生产协同的理论与对策等问题,选取兰坪、云龙、永胜、康定以及波密县为典型示范区,开展国家重点研发计划活动,以西南高山峡谷不同类型区水土流失分异规律和综合防治为主线,按照三个层次开展水土流失综合防治与示范研究,攻克高精度土壤侵蚀预报模型与监测技术瓶颈,形成生态系统服务整体提升的“水土流失防治-生态系统服务-民族经济发展”的多目标水土流失综合防治技术体系,最终为西南高山峡谷区生态系统恢复提供科学依据与技术支撑。The Southwest Alpine and Canyon Area covers the“Seven Mountain Ranges and Six Rivers”in the Hengduan Mountains Region of China.It serves as an important ecological security barrier for the national“Three Zones and Four Belts”strategy and plays a crucial role in safeguarding national ecological security and promoting high-quality regional development.Due to the complex terrain and diverse planting methods of various ethnic groups,the region exhibits significant differentiation in soil erosion,with complex causes and prominent conflicts.Additionally,the accuracy in monitoring and forecasting soil erosion in the area is much lower,and the severity of soil erosion has been underestimated,making soil erosion a serious constraint on the region′s sustainable socio-economic development.In view of the zonal law and its key driving mechanism of soil and water loss differentiation and evolution,the response and its prevention and control mechanism of soil and water loss to agricultural cultivation,high and steep terrain,karst geology,freeze-thaw and other complex driving conditions,as well as the overall improvement of ecological service function and the countermeasures of ecological production coordination in ethnic gathering areas,the research team selected Lanping,Yunlong,Yongsheng,Kangding and Bomi County as typical demonstration areas to carry out the“National Key R&D Program of China”named“Technology and Demonstration of Comprehensive Prevention and Control of Soil and Water Loss in Southwest Alpine and Canyon Areas(2022YFF1302900)”.The main line of this research is the differentiation law and comprehensive prevention and control of soil and water loss in different types of alpine and canyon areas in Southwest China.Comprehensive soil erosion control and demonstration research should be carried out at three levels(basic theoretical research,technology model development,and integrated optimization demonstration),the focus is on studying the characteristics,evolution patterns,and key driving factors of
