摘要
以衡东县栗木小流域为研究对象,通过样方地调查的方法调查流域内植物种类、植被覆盖度、土壤厚度等,采用现场测量的方法测量沟道长度、沟谷比降、平均沟坡坡度;谷坊规格、淤积长度、淤积宽度等因子,分析研究南方丘陵紫色岩母质裸露地区沟道综合治理措施布局及其效益,在此基础上,提出紫色岩母质裸露地区沟道治理优化模式。
In order to control soil and water losses effectively in the purple rock area and improve the site condition and ecological environment gradually, on the basis of field investigation and existing data, every administering method in purple rock of complete naked region in south China is analyzed from such aspects as characteristic, degree and morphologic types of water loss and soil erosion, etc. And every administering method is analyzed, especially which kind of plants should be planted in the adaptive areas and which project method is suited to. Based on all above, the optimum patterns of synthetic administration about water loss and soil erosion in every region type is selected.
