近年来,三亚持续系统实施三亚湾海洋生态修复工程,采取工程、技术、生物等多种措施,对三亚湾海洋自然生态环境进行保护和修复,全力推进“六水共治”工作。
In recent years, Sanya has been continuously implementing the Sanya Bay Marine Ecological Restoration Project, taking various measures such as engineering, technology, and biology to protect and restore the marine ecological environment of Sanya Bay.
5月份,在三亚湾海洋生态修复工程项目(西岛及附近海域)施工现场,工人们正忙着制作人工鱼礁,现场一派热火朝天的景象。不远处,上百个巨大的混凝土人工鱼礁体整齐排列,全部完工后它们将沉入海底,为海洋生物搭建近300万平方米的“新家”。
In May, workers were busy building artificial reefs at the Sanya Bay Marine Ecological Restoration Project construction site. Not far away, hundreds of giant concrete artificial reefs are being neatly arranged, and when completed, these reefs will be placed on the bottom of the sea, creating nearly 3 million square meters of "new home" for marine life.
人工鱼礁的尺寸为6米×6米×6米,单个重量约90吨,兼具抗倾覆性和结构稳定性,且鱼礁表面积较大,更有利于生物附着。人工渔礁如同一个巨大的空心魔方,上面有许多孔洞,投放后,鱼类可以钻进去繁殖、生长、避敌,相当于给鱼造个“安全屋”,可以遏制非法捕捞作业,缓解海底荒漠化。
The size of the artificial reef is 6 x 6 x 6 meters, with a single weight of approximately 90 tons. It has both anti-overturning and structural stability, and the surface area of the reef is larger, which is more conducive to biological attachment. Artificial fishing reefs have many holes. Once installed, fish can burrow in to breed, grow and avoid predators, creating a "safe house" for fish. These reefs can deter illegal fishing and reduce seabed desertification.
项目主要建设内容为渔业资源保护工程,包括人工渔礁建设和增殖放流两部分,将在西岛附近海域建设1个约300公顷人工鱼礁区以及投放320个人工鱼礁,以分阶段放流的方式增殖放流鲷科类、石斑鱼类等岩礁性鱼类14.5万尾。
The main construction content of the project is the protection of fishery resources, including the construction of artificial reefs and stock enhancement. A 300-hectare artificial reef area and 320 artificial reefs will be constructed in the marine areas near the West Island to gradually release 145,000 species of fish, such as Sparidae and groupers.
值得一提的是,三亚湾海洋生态修复是一个系统工程,共分三期进行。该工程通过科学划区种植珊瑚、增殖放流,以及对三亚湾生境、海洋水文动力、海洋生物生态等进行跟踪监测,促进和维持海洋生态系统自然恢复。
The restoration of marine ecology in Sanya Bay is a systematic project with three phases. This project promotes and maintains the restoration of marine ecosystems by planting corals, breeding and releasing fish fry, and tracking and monitoring the habitat, marine hydrodynamics, and marine ecology of Sanya Bay.
2022年,三亚环投集团实施一期凤凰岛及附近海域修复项目,移植珊瑚礁15000株,人工鱼礁区建设110公顷,增殖放流鱼苗3.4万尾。目前,正在开展二期西岛及附近海域项目建设,预制完成人工鱼礁165个,预计6月底开始投放。
In 2022, the first phase of the Phoenix Island Restoration Project will include the transplantation of 15,000 coral reefs, the construction of 110 hectares of artificial reef areas, and the breeding and release of 34,000 juvenile fish. Currently, construction of the second phase of the West Island Near Sea Area Restoration Project is underway, and 165 artificial reefs have been prefabricated and are expected to be finished by the end of June.
三亚湾海洋生态修复工程项目的实施,将有效修复与保护海洋生态系统,提高周边海域海洋生物多样性及均匀性,为更多的海洋底栖生物提供食物来源、栖息和繁衍场所,助力海洋环境质量持续稳定改善。同时,此项目也能高效地补充渔业资源,实现海洋开发利用与生态环境保护的协调统一。
The implementation of Sanya Bay Marine Ecological Restoration Project will effectively restore and protect marine ecosystem, improve marine biodiversity and uniformity, provide food sources, habitats and breeding grounds for more marine benthic organisms, and continuously improve marine environmental quality. At the same time, this project can effectively supplement the fishery resources and achieve the consistency between the development of the marine area and the ecological and environmental protection.
