摘　　要：由于水土流失监测是掌握特定区域水土流失面积、强度和动态变化情况的重要手段,对九洲江广西流域进行了水土流失动态监测,分析了该区域水土流失消长情况。结果表明:九洲江广西流域的水土流失状况向好的方向上发展,2019年水土流失面积较2018年度减少13.07 km^(2),土壤侵蚀强度呈现出高强度向低强度转化的趋势。此结果可为水土流失综合治理、水资源保护和河长制度等决策提供数据支撑。Soil erosion monitoring is an important way to grasp the area,intensity and dynamic changes of soil erosion in a specific watershed.This paper analyzed the growth and decline of soil erosion in the region through the dynamic monitoring of soil erosion in the Guangxi drainage area of Jiuzhou River.The results showed that the soil erosion in the Guangxi Basin of Jiuzhou River was developing in a good direction.In 2019,the area of soil erosion decreased by 13.07 km^(2) compared with 2018,and the soil erosion intensity showed a trend of high intensity to low intensity.The results have provided data support for comprehensive management of soil erosion,water resources protection and river chief systems.
