摘　　要：沿海植物带能有效地减轻海啸带来的灾害。为进一步揭示沿海植物带对海啸波的消浪特性,基于红树林和海滩林两类典型沿海植物带,分别采用不同的材料和假设对两类植物进行参数化处理,使用孤立波模拟海啸波,开展了物理模型实验研究。结果表明波高、淹没度、无量纲水深和无量纲长度均在不同程度上影响植物消浪特性。两种模型的消浪特性随研究因素的变化规律基本相同,仅在淹没度为1时,消浪效果随波高的变化规律存在差异。The coastal vegetation belt can effectively mitigate tsunami disaster.In order to further understand tsunami wave dissipation by coastal vegetation belts,based on two kinds of typical coastal vegetation belts,mangrove and beach forests,two kinds of vegetation were parameterized with different materials and assumptions,and solitary waves were used to simulate tsunami waves.The results showed that wave height,submergence ratio,dimensionless depth and dimensionless thickness all impacted wave dissipation by vegetation in different degrees.Wave disspation by the two kinds of vegetation was proven to be similar with respect to experimental results.When the submergence ratio was equal to 1,wave height variations for the two kinds of vegetation differed.
