深圳西部海岸带生态保护和修复策略研究

Research of the Ecological Protection and Restoration Strategies on the West Coastal Zone in Shenzhen

海岸带位于海陆的交界处,受到海洋和陆地的交互影响,属于生态脆弱的区域,在为城市发展提供生物资源和生态系统服务的同时,更易受到复杂自然灾害和人类活动的干扰。深圳作为粤港澳大湾区的核心城市之一,在过去的几十年中经济快速发展。围填海活动尽管解决了一时的用地紧张等问题,却给深圳海岸带生态系统带来了严重的生态问题,以西海岸带为例,呈现出过人工化、硬质化的倾向,进而造成了环境污染严重、生境破碎化、生物多样性降低等生态问题。本文通过梳理深圳西海岸带存在的具体问题,针对性的提出控制陆源污染,加强水质治理、空间景观重塑,构建滨海景观长廊、通过红树林植被种植与保育促进生态价值的提升、进行海堤生态化建设,对人工岸线进行生态化改造等生态修复策略,以期为深圳开展海岸带生态保护修复工作提供参考。

Located at the junction of sea and land,the coastal zone has unique development advantages and provides important ecological value services.As one of the core cities of Guangdong,Hong Kong and Macao metropolitan area,Shenzhen has developed rapidly in the past few decades.Although reclamation activities have solved the temporary land shortage and other problems,it has brought serious ecological problems to the coastal ecosys-tem of Shenzhen.Taking the west coastal zone as an example,it shows a tendency of artificial and hard,resulting in serious environ-mental pollution,habitat fragmentation,biodiversity reduc-tion and other ecological problems.By combing the spe-cific problems existing in the west coast of Shenzhen,this study puts forward ecological restoration strategies such as controlling land-based pollution,strengthening water quality control,reconstructing spatial landscape,building coastal landscape corridor,promoting the improvement of ecological value through mangrove vegetation planting and conservation,ecological construction of seawall,and eco-logical transformation of artificial coastline.It is expected to provide reference for Shenzhen to carry out coastal zone ecological protection and restoration.
