沿海盐沼生态系统只占地球陆地表面的一小部分，但却提供了具有重大全球经济和社会价值的广泛生态系统服务。这些环境目前面临着与气候变化、海平面上升、发展和水质恶化有关的重大挑战，因此成为一系列管理计划的重点。越来越多的软工程技术，如管理调整（MR）被用来恢复和重建这些环境，主要是由需要栖息地（重建）的创造和可持续的沿海防洪。这种恢复计划也有可能提供额外的生态系统服务，包括气候调节和废物处理。然而，这些地点经常受到其以前土地使用的实际影响，并且缺乏对这种“干扰”如何影响生态系统服务的提供或恢复系统中生态、物理和生物地球化学过程之间复杂联系的了解。通过探索目前的数据，本文确定恢复网站的水文，地貌和水动力功能可能会显着受损的自然“不受干扰”的系统和形态，沉积物结构，水文和溶质迁移之间的联系知之甚少。这对种子的提供、适合植物生长的非生物条件的提供、微生境的发展和营养物/污染物的循环都有影响，并可能影响生态系统服务的提供，包括生物多样性、气候调节和废物处理。这就要求我们改变在这些环境中的研究方法，需要在一系列的空间和时间尺度上进行综合的跨学科研究，将密集和广泛的研究设计结合起来。
Coastal saltmarsh ecosystems occupy only a small percentage of Earth's land surface, yet contribute a wide range of ecosystem services that have significant global economic and societal value. These environments currently face significant challenges associated with climate change, sea level rise, development and water quality deterioration and are consequently the focus of a range of management schemes. Increasingly, soft engineering techniques such as managed realignment (MR) are being employed to restore and recreate these environments, driven primarily by the need for habitat (re)creation and sustainable coastal flood defence. Such restoration schemes also have the potential to provide additional ecosystem services including climate regulation and waste processing. However, these sites have frequently been physically impacted by their previous land use and there is a lack of understanding of how this ‘disturbance’ impacts the delivery of ecosystem services or of the complex linkages between ecological, physical and biogeochemical processes in restored systems. Through the exploration of current data this paper determines that hydrological, geomorphological and hydrodynamic functioning of restored sites may be significantly impaired with respects to natural ‘undisturbed’ systems and that links between morphology, sediment structure, hydrology and solute transfer are poorly understood. This has consequences for the delivery of seeds, the provision of abiotic conditions suitable for plant growth, the development of microhabitats and the cycling of nutrients/contaminants and may impact the delivery of ecosystem services including biodiversity, climate regulation and waste processing. This calls for a change in our approach to research in these environments with a need for integrated, interdisciplinary studies over a range of spatial and temporal scales incorporating both intensive and extensive research design.
