中文摘要：红树林具有显著的消波作用,现场实测台风期间红树林波能数据可为物理模型和数值模拟提供基础数据,也可为海岸防灾减灾提供依据。通过对广东湛江雷州湾海岸红树林示范区6个测站同步观测到的波浪数据进行分析,探讨分析了台风期间红树林的消波效果以及变化规律。结果表明:波高衰减率随着岸边红树林密度增大而增大;红树林对波能的平均衰减率为56.28%,没有红树林的光滩波能衰减率为28.33%,红树林的波能衰减率约为光滩的2倍;波浪向红树林传播过程中,谱宽度ε变大,谱尖度Q_(p)和波陡S_(s)减小,谱峰周期T_(p)增大,波能衰减主要发生在高频部分。

外文摘要：Mangroves have a significant wave attenuating effect.Wave energy data collected in situ from mangrove forests during typhoons can provide essential input for physical modeling and numerical simulations,as well as a scientific basis for coastal disaster prevention and mitigation.This study analyzes wave data synchronously recorded at six stations in the coastal mangrove demonstration zone of Leizhou Bay,Zhanjiang,Guangdong Province,to investigate the wave attenuation effect of mangroves and its variation during a typhoon.The results show that the wave height attenuation rate increases with mangrove density.The average wave energy attenuation rate by mangroves is 56.28%,while that of bare tidal flats without mangroves is 28.33%—approximately half that of mangroves.During wave propagation through mangroves,spectral widthεincreases,while spectral peakedness Q_(p)and wave steepness S_(s)decrease,and the peak period T_(p)becomes longer.Wave energy attenuation primarily occurs in the high-frequency range.
