摘　　要：基于自然灾害风险分析,探讨海岸线生态修复机制下的景观策略。以广东江门市台山海宴镇海岸生态修复为研究对象,运用ArcGIS、Phoenics等工具,模拟场地内台风、风暴潮、海岸侵蚀等自然灾害的风险强度并进行可视化分析,提出基于自然灾害影响的海岸线生态修复景观策略—海防景观一体化,包括4种模式:多重生态防护体系(离岸潜水坝、红树林、生态防波堤、防浪沙丘、防风林)的复合景观模式、河海共治水系改善模式、海水稻土壤治理模式和"弹性"海岸空间模式。Based on natural disaster risk analysis,this paper explores landscape strategies under the coastline ecological restoration mechanism.Taking the coastal ecological restoration of Taishan Haiyan Town in Jiangmen City,Guangdong as the research object,using ArcGIS,Phoenics and other tools to simulate the risk intensity of natural disasters such as typhoon,storm surge,and coastal erosion in the site and perform visual analysis,the paper puts forward a coastline ecological restoration landscape strategy based on the impact of integration of natural disasters-coastal defense and landscape,including four models:a composite landscape model of multiple ecological protection systems(offshore diving dams,mangroves,ecological breakwaters,wave-breaking dunes,and windbreak forests),improvement model of river and sea cogovernance water system,sea-rice soil governance model and“flexible”coastal space model.
