| 生态海岸通过整合盐沼等植被缓冲带，可以增强对风暴潮和波浪的自然防御功能，同时展现出可持续和自适应特性。本研究以海三棱藨草（Scirpus mariqueter）为研究对象，通过分析现场观测的波浪数据，对盐沼植被缓冲带的消浪效果进行了定量评估。结果表明，在不同海岸区域的同种植被中，波浪透射系数与相对宽度显著相关，且植被区内波浪衰减速率呈现先快速后减缓的变化趋势。基于此，本研究推导了一个基于植被相对宽度的波浪透射系数经验公式：$ {k}_{t}={\mathrm{e}}^{\left(-0.03\tfrac{w}{{h}_{0}}+0.67\right)} $，并通过实测数据验证了该公式的预测精度（R2 = 0.86）。本研究成果对快速评估盐沼植被缓冲带的防护能力具有重要意义，同时为海岸带的可持续防护策略提供了科学依据。 |

| Abstract: |
| By integrating vegetative buffer zones such as salt marshes，eco-coasts can enhance natural defense capabilities against storm surges and waves and show the sustainable and adaptive characteristics of the ecological coastline. Focusing on Scirpus mariqueter buffer zones，this study quantitatively evaluated their wave-dissipation effectiveness in salt marsh vegetation buffer zones through analysis of wave observation data in situ. Results indicate a significant correlation existing between wave transmission coefficients of the same vegetation species in different coasts and their relative width. Moreover，the wave attenuation rate within vegetated zones exhibits an initial rapid decline followed by a slower rate. Thus，an empirical formula for wave transmission coefficient $ {k}_{t}={\mathrm{e}}^{\left(-0.03\tfrac{w}{{h}_{0}}+0.67\right)} $ is developed using relative vegetation width，with its predictive accuracy validated by field data (R² = 0.86). The findings provide an effective method for rapid assessment of salt marsh vegetation buffer zones protection capacity and offer scientific support for sustainable coastal protection strategies. |
