| Abstract: | Silt dams play active and important role in conserving soil and water. On the basis of concluding and summarizing the past and present situation of the effect of silt dams for conserving soil and water in 4 aspects, including the calculation methods of blocking and reducing sediment ,the effect and role in conserving soil and water ,the mechanism in reducing erosion intensity, the relationship between the sedimentation characteristics and erosion type evolution in small watersheds, the problems existed in present research were analyzed,and the future developing direction in these fields were also pointed out and discussed, so that the role of silt dams in conserving soil and water can be evaluated scientifically and provide some references for future research and construction of silt dams on Loess Plateau. |
