摘要
目前潮滩盐沼湿地退化消失已经成为全球性的问题,而盐沼植被起到了消浪、缓流、截沙、固沙等作用,对潮滩动力地貌过程产生重要影响。因此,深入研究滨海盐沼植被在不同植被参数下的消浪效果具有重要意义。为了模拟和分析不同植被参数对波浪的影响,采用一维岸滩演变模型来模拟波浪在盐沼植被区的传播情况。通过对比模拟的波高变化,直观地了解不同植被参数下波高沿程的变化特征,进而准确揭示植被的消浪特性。研究结果表明:盐沼植被的消浪作用会随着密度、高度、直径的增加而增强,但消浪能力存在临界值。不同植被参数对波浪削弱强度各有差异,其中直径对波浪的影响最为显著。
At present,the degradation and disappearance of tidal flat salt marshes has become a global problem,and salt marsh vegetation has played a role in wave absorbing,current slowing,sand retention,and sand fixation,which has an important impact on the dynamic geomorphological process of tidal flat.Therefore,it is of great scientific significance to study the wave dissipation effect of coastal salt marsh vegetation in different vegetation parameters.In order to simulate and analyze the influence of different vegetation parameters on waves,a one-dimensional beach evolution model was used to simulate the propagation of waves in the salt marsh vegetation area.By comparing the simulated wave height changes,the variation characteristics of wave height along the path under different vegetation parameters are intuitively understood,and then the wave dissipation characteristics of vegetation can be accurately revealed.The results show that the wave dissipation effect of salt marsh vegetation will increase with the increase of density,height and diameter,but there is a critical value of wave dissipation capacity.Different vegetation parameters have different effects on wave weakening intensity,among which diameter has the most significant effect onwave。
