摘要
影响小流域水土流失的因素有降雨因子、植被盖度因子等,以陕西省宁陕县寨沟小流域5个不同植被覆盖度的侵蚀观测小区为研究对象,采用灰色关联度方法,对影响因子进行分析,为区域水土流失防治工作提供参考。
Factors affecting soil erosion in small watershed include rainfall factor and vegetation coverage factor. Taking five eroded observation plots with different vegetation coverage in Zhaigou small watershed of Ningshan county,Shaanxi province as research object,using gray relational degree method,influencing factors were analyzed comparatively. It would provide references for prevention and control of soil erosion.
