盐沼和泥滩为社会提供许多有价值的服务，包括海岸保护。先前的研究已经确定了波衰减与栖息地宽度的非线性关系以及随植被类型的变化。然而，沿海保护水平的空间差异尚未在全国范围内量化。国家尺度盐沼栖息地的空间分布和精细（50 m）尺度结构与 200 m 尺度的波浪取值计算相结合。计算了栖息地周围 5 公里范围内的海岸线区域因栖息地波浪衰减而产生的有效波浪暴露。有效的波浪暴露与建筑物和农田位置的数据层相结合，以评估相关的保护措施。根据人类基础设施和农田的接近程度，计算了英格兰和威尔士整个海岸线的海岸保护指标。在将沿海保护的现有地方和区域数据扩大到国家层面时，我们可以研究沿海保护在区域之间的差异，并为沿海生态系统管理者选择对保护至关重要的沼泽地提供标准。我们的指数显示，英国东部和南部的沼泽对人类基础设施提供了最大程度的保护，这些盐沼位于相对开放的海岸线上，附近有建筑区和农业。
Saltmarshes and mudflats provide many valuable services to society, including coastal protection. Previous studies have established the nonlinearity of wave attenuation with habitat width, and variation with vegetation type. However, spatial variation in the level of coastal protection has not been quantified on a national scale. Spatial distribution and fine (50 m) scale structure of saltmarsh habitat at a national scale was combined with calculations of wave fetch at a 200 m scale. Effective wave exposure as a result of wave attenuation over habitat was calculated for areas of coastline within 5 km of habitat areas. Effective wave exposure was combined with data layers on building and farmland locations in order to assess relative protection provision. A metric of coastal protection was calculated for the entire coastline of England and Wales, based on the proximity of human infrastructure and farmland. In scaling existing local and regional data on coastal protection to a national level, we may examine how coastal protection varies regionally and provide a criterion for coastal ecosystem managers to select marshes critical for conservation. Our index shows greatest protection of human infrastructure by marshes in the east and south of the UK, where saltmarshes are on relatively open coastlines with nearby built-up areas and agriculture.
