摘　　要：根据对粤东一岬间海滩冬夏季采集的表层泥沙的粒度分析结果,本文采用沉积物输运趋势概率模式对海滩泥沙沿岸运动方向作了统计分析,进而从波折射数值计算得到的波能流的沿岸分布讨论了对沿滩输沙的季节性效应.The longshore movement directions of beach sands are statistically analyzed by using the probability model of sediment transport trends, based on the results of grain size analysis of the beach sands collected from a beach between the headlands located along the easten Guangdong coast during different seasons. In addition, the seasonal effects of long-shore distribution of wave energy fluxes computed by the numerical model of wave refraction on the variations of beach sediment transport directions are discussed in the paper.
