Practice of Coastal Zone Regulation and Ecological Restoration in Kaozhouyang under the Background of Beautiful Bay Construction

摘要:

惠州市考洲洋海岸带作为自然滩涂及围网养殖水域，生态 环境破坏较为严重，面临红树林退化严重、水体富营养化、航道 堵塞、海岸景观缺乏等问题，其海岸整治、生态修复面临一定的 技术难点如红树林成活率提升、滩涂整治、红树林栽植等。基于 “美丽海湾建设”背景，针对生态环境问题及工程技术难点，提 出整治及修复策略，包括加强陆源污染控制、堆填整治滩涂、科 学合理栽植及养护、营造多功能红树林生境、建设海洋环境观测 设施以及构建海岸带生态湿地公园。并对项目实施之后产生的生 态效益、社会效益和经济效益进行总结与评价。

Abstract:

As a natural beach and purse seine aquaculture water area,the ecological environment of Kaozhouyang coastal zone in Huizhou City is seriously damaged. It is faced with serious mangrove degradation,water eutrophication, channel blockage, lack of coastal landscape and other problems. Its coastal regulation and ecological restoration are faced with certain technical difficulties, such as the improvement of mangrove survival rate, beach regulation, mangrove planting and so on.Based on the background of Beautiful Bay Construction, aiming at the ecological environment problems and engineering technical difficulties,some remediation and restoration strategies are proposed, including strengthening the control of land-based pollution, reclamation of tidal flats, scientific and reasonable planting and maintenance, creating multi-functional mangrove habitat, constructing marine environment observation facilities and coastal ecological wetland park. And the ecological benefits, social benefits and economic benefits after the implementation of the project are summarized and evaluated.
