摘　　要：通过对2003年7月采集的华南沿海12条海滩剖面(3种海滩类型)的76个沉积物样品粒度分析,讨论了物质来源、地形地貌、风暴、水动力条件以及后滨向陆的极限高度等对海滩沉积物的性质与分布的影响.研究得出,后滨向陆的极限位置处于相对稳定的状态;后滨的极限高度随着滩面粒径的增大而增加.With the data of granulometric character from 76 sediment samples of 12 pro/iles in 3 types of beaches along the South China coast, the effects of natural environmental factors, such as sources of sediments, topography and morphology, storm events, hydrodynamic condition, the height of the landward limit of the backshore, and the like on the feature and distribution of the sediments are discussed. It concludes that the landward limit of backshore is relatively stable and the height of landward limit at the backshore increases with increasing grain size.
