摘要
以沂蒙山区曲阜九仙山小流域为研究区域,基于"3S"技术,对2009年九仙山小流域土壤侵蚀特征及其环境影响因子进行了系统研究。研究结果表明:九仙山小流域土壤侵蚀在侵蚀强度上呈现整体以轻度侵蚀、中度侵蚀为主,局部有强烈和极强烈侵蚀的土壤侵蚀特征;土地利用、植被盖度、坡度、海拔等环境因子对流域土壤侵蚀影响密切。研究成果可为小流域水土保持决策提供参考。
Jiuxianshan watershed undergone water and soil conservation ecological restoration in Qufu was taken as the study area,and the soil erosion situation and the relationship of the environmental factors and soil erosion were studied by using 3S technique.The results show that： Jiuxianshan watershed on the whole belongs to light erosion and moderate erosion,and serious and extremely erosion is only in some areas;The relationships among soil erosion and the way of land utilization,vegetation coverage,the slope,the environmental factors are close.The research results can provide technical support and determine the reasonable water and soil conservation measures.
