| 摘 要： | 利用土壤侵蚀模数、土壤容许流失量研究三峡库区相同土壤侵蚀类型区内不同地点的水土保持措施,并用这一综合指标对水土保持措施进行评价.研究表明:采用土壤侵蚀模数、土壤容许流失量这一综合指标能够分析相同侵蚀类型区内的土壤侵蚀程度,并可以评价水土保持措施的水土保持作用;植物篱水土保持措施确实能够显著的降低土壤侵蚀的程度;退耕还林以及退耕还草具有显著的水土保持效果;由于观测时间、降水历时和降水强度等因素限制,土壤侵蚀模数在人工降水条件下评价水土保持措施时,不能充分发挥作用,只能在侵蚀趋势上反映各个区域的侵蚀差异.

| Abstract: | This paper researched the soil and water conservation measures in different plots belonged to the same style of erosion area in Three Gorges reservoir area by using the comprehensive index of the soil erosion modulus and the concept of soil loss.The results show that using the comprehensive index,we can analyze the degree of soil erosion in the same style erosion area and evaluate the soil and water conservation measure;hedgerow can reduce the degree of soil erosion,and loss amount of different hedgerow tre... |
