元江—红河界河地区土壤侵蚀研究

Study on the soil erosion in the Yuanjiang-Honghe boundary river areas

为支撑我国界河地区国土防护工作,以中国、越南交界的元江—红河界河地区为研究区,基于3S技术进行界河地区的土壤侵蚀研究。采用Landsat 8卫星遥感数据,基于水体指数、植被覆盖度、土壤可蚀性及坡度进行土壤侵蚀强度研究,初步建立了界河地区的土壤侵蚀强度遥感评价方法,提出了界河地区国土防护措施与建议。

In order to provide support for the territorial protection of our boundary river areas, the authors has taken the Yuanjiang - Honghe boundary river areas in China and Vietnam border as the study areas, and studied the soil erosion of the study areas by 3S technology in the study areas. Landsat 8 satellite remote sensing data and the soil erosion factors （ normalized difference water index, vegetation coverage, soil erodibility and slope） were used to study the intensity of soil erosion. The remote sensing evaluation method about the intensity of soil erosion in the boundary river areas was preliminarily established. And some measures and suggestions for the territorial protection of our boundary river areas were put forward.
