摘要

长江流域土壤侵蚀类型多样、侵蚀机理复杂,是我国水土流失最严重的区域之一。本研究以长江流域国家级水土流失重点防治区为对象,基于多源遥感数据,采用资料收集、室内解译和实地调查相结合的方法,获取土壤侵蚀影响因子,利用中国土壤流失方程CSLE(Chinese Soil Loss Equation)和风力侵蚀模型计算土壤侵蚀模数,并依据《土壤侵蚀分类分级标准》(SL 190—2007)等技术标准,评价监测区土壤侵蚀强度,实现长江流域国家级重点防治区2018年全覆盖水土流失监测,并实现以重点防治区和县级行政区为单元的水土流失消长分析。结果显示:土壤侵蚀总面积及各防治区土壤侵蚀面积均呈不同程度的下降趋势,水土流失强度也在逐步减轻。研究表明,该区域水土流失得到有效控制,水土流失预防和治理效果明显。本研究为超大尺度水土流失动态监测进行了技术尝试,可为水土保持监管、地方政府水土保持目标责任考核等提供有效技术途径和重要参考。
        The soil erosion types in the Yangtze River Basin are diverse and the erosion mechanism is complex, which is one of the most serious areas of soil erosion in China. This study takes the national water and soil loss key prevention and control area of the Yangtze River Basin as the target, based on multi-source remote sensing data, using data collection, indoor interpretation and field investigation to obtain soil erosion impact factors, using the CSLE(Chinese Soil Loss Equation) and the wind erosion model to monitor the full coverage of soil erosion in the 2018 state-level key prevention and control areas of the Yangtze River Basin, and to realize the analysis of water and soil loss and growth in key prevention areas and county-level administrative areas.The results showed that the total area of soil erosion and the area of soil erosion in each control area showed a decreasing trend, and the intensity of soil erosion was gradually reduced. Studies have shown that soil erosion in this area is effectively controlled, and soil erosion prevention and treatment effects are obvious. This study has carried out technical attempts for the dynamic monitoring of super-large scale soil erosion, and provides effective technical approaches and important references for water and soil conservation supervision and responsibility assessment of water and soil conservation target in local government.
