摘　　要：对粤西水东弧形海岸长时段重复测量海滩剖面的因子分析说明了各特征岸段剖面的主要地貌状态。频域分析反映了各岸段海滩体积的月周振动峰值和对波能的响应特征。实测海滩剖面波动过程的计算则指示了当前各剖面的蚀积状态。By method of factor analysis, this paper deals with the main geomorphological states of the beach profiles at three shore sectors based on repeated measured beach profiles over long periods. The energy density spectra indicate monthly peaks in beach volume change. Coherency spectra and lag time spectra show the features of beach volumes in different sectors response to wave energy variations. Calculation on the beach profile variation processes exhibites the present state of erosion-deposition.
