Abstract

After the Great East Japan Earthquake in 2011, the Japanese government reconstructed coastal protection facilities to mitigate extreme disasters and coastal erosion. However, the substantial compression of coastal zones poses a challenge in coping with sea level rise, while maintaining a sustainable coastal ecosystem. To clarify the impact of environmental factors and sea level rise on coastal ecosystems in highly developed regions, this study integrated field surveys, geo-detector analysis, and coastal inundation models into the research framework. It explored the relationship between environmental factors and vegetation patterns and predicted the inundation areas and vegetation survivorship of 12 transects in the study area from 2030 to 2150. The results indicated that the distance from the tide embankment (DTE) and elevation (DEM) were the main driving factors, and the combination of the potential of hydrogen (pH) and DTE had a major impact on vegetation coverage. Notably, the distribution of vegetation was positively correlated with the width of the coastal zone, and when the width was less than 60 m, vegetation could not survive. With sea level rise, almost no vegetation will survive until 2150. Appropriate coastal width and height are conducive to maintaining the sustainability of coastal ecosystems.

预测已修建防潮堤的沿海地区海平面上升的影响
2011 年东日本大地震后,日本政府重建了海岸保护设施,以减轻极端灾害和海岸侵蚀。然而,海岸带的大幅压缩给应对海平面上升,同时维持可持续的海岸生态系统带来了挑战。为阐明环境因素和海平面上升对高度发达地区沿海生态系统的影响,本研究将实地调查、地理 探测器分析和沿海淹没模型纳入研究框架。该研究探讨了环境因素与植被模式之间的关系,并预测了 2030 年至 2150 年研究区 12 个断面的淹没面积和植被存活率。结果表明,潮堤距离(DTE)和海拔高度(DEM)是主要的驱动因素,而氢电位(pH)和 DTE 的组合对植被覆盖率有重大影响。值得注意的是,植被的分布与海岸带的宽度呈正相关,当宽度小于 60 米时,植被无法生存。随着海平面上升,2150 年前几乎没有植被可以存活。适当的海岸宽度和高度有利于维持海岸生态系统的可持续性。

期刊介绍: Landscape and Urban Planning is an international journal that aims to enhance our understanding of landscapes and promote sustainable solutions for landscape change. The journal focuses on landscapes as complex social-ecological systems that encompass various spatial and temporal dimensions. These landscapes possess aesthetic, natural, and cultural qualities that are valued by individuals in different ways, leading to actions that alter the landscape. With increasing urbanization and the need for ecological and cultural sensitivity at various scales, a multidisciplinary approach is necessary to comprehend and align social and ecological values for landscape sustainability. The journal believes that combining landscape science with planning and design can yield positive outcomes for both people and nature.
