英文摘要：

In this paper, the siltation promotion and erosion control techniques for beach sediments are divided into three types, impermeable solid type, ecological type and new structure type. The working mechanisms of the three types of technique and the main factors needing attention in their applications are respectively expounded. The advantages and disadvantages of these techniques are summarized by using the cases of their applications to coastal engineerings. The recent developments in the siltation promotion and erosion control techniques are introduced, and it is pointed out that the developing trends of these techniques are safe, economical, efficient and environment-friendly. Therefore, the structures characterized by light weight, low cost, small resistance to flow conveyance and being easy to construct are highly, recommended.
