摘　　要：从祥云岛的地理位置上来看,对监测区A1—A9、B1—B5剖面岸滩演变有重要影响的为NE、NW向浪以及SW向浪。3个方向的强浪比率分别为1.58%、0.98%、0.45%,对岸滩侵淤的影响作用也与强浪比率呈明显的相关性。从海滩养护类型上划分,祥云岛所属的养滩类型为同相养滩中的平直砂岸养滩和直岸凸滩养滩,此两种养滩类型均对波浪作用的响应比较强烈,必须辅以"硬工程"加强防护。Around the Xiangyun island, waves in northeast,northwest and southwest directions play key roles in beach evolution as seen along the monitoring profiles from A1 to A9 and the profiles from B1 to BS. The ratio of waves from the three directions is 1.58%, 0.98% and 0.45% respectively, and they are related to the erosion and deposition of beach. In terms of the types of beach nourishment, the Xiangyun island belongs to a straight sand coast of an in-phase beach. As such a beach has a strong response to wave action, some ＂hard projcets＂ are indispensable.
