滨海植物的海岸带减灾特性研究综述

滨海植物广泛分布于海岸带，形成了红树林、盐沼及海草床等湿地系统，具有重要的生态价值和海岸带减灾作用。不同滨海植物的结构和刚柔特性不同，植物群密度及其分布的海洋水动力环境也有差异，因而具有不同的海岸带减灾特性。前人就不同植物类型的海岸带减灾特性开展了丰富的理论研究，本文系统地整理了滨海植物的海岸带减灾事例，从现场观测、水槽试验、数值模拟和理论模型等方面概述了植物群的消浪、阻流、促淤、防冲等相关研究成果，介绍了滨海植物海岸带减灾功能的一般评价方法，分析了各方面研究的不足及后续发展方向。

A review of coastal disaster mitigation by vegetation

Vegetation distributed widely along shorelines, forming mangrove forests, salt marsh wetlands, and seagrass beds. These ecosystems are highly valued for their ecological and coastal disaster mitigation service. The ability to mitigate the influence of coastal storms and tsunami waves varied among different types of vegetation due to the differences in plant morphologic and mechanical properties, vegetation density, and hydrodynamic conditions. Vast empiric and theoretic studies have been performed to investigate the characteristics of coastal disaster mitigation by different types of vegetation. A systematic review of previous studies including field surveys, flume experiments, numeric modeling, and theoretic analysis was presented. Firstly, the historic events showing the storm and tsunami mitigation by coastal vegetation were summarized. Second, detailed studies of wave dissipation, flow resistance, sediment deposition of coastal vegetation were presented. Finally, the methods to evaluate the ability of coastal disaster mitigation by vegetation were introduced.
