【 摘 要 】

The paper analyses the results of field investigations into the evolution of the shoreline and dune toe positions in a multi-bar,dissipative coastal zone. The correlations between the changes in the shoreline and the dune toe range from -0.4 to 0.8. It is most often the case that the dune toe is stable while the shoreline moves. Consistent cross-shore migration is slightly more likelyto happen than the divergent or convergent movements of both lines. Shoreline retreat and advanceattain respective rates of 0.7 m day^-1 and 0.4 m day^-1. Deep-water wave energy of about 50 kJ m^-1 constitutes the boundary between shore accumulation and erosion.
