Recently, the Provincial Department of ecological environment issued the 14th five year plan for marine ecological environment protection in Guangdong Province (hereinafter referred to as the plan), which proposed to focus on promoting the construction of 15 beautiful bays by 2025; Looking forward to 2035, more than 80% of the key bays in the province will be basically built into a beautiful bay with "clear water, clean beaches, abundant fish and gulls and harmonious sea of people". Promoting high-quality development of coastal economic belt with marine protection The plan first proposes to boost the high-quality development of the coastal economic belt with the high-level protection of the marine ecological environment, and strive to build a new pattern of green development. At the source, we will establish and improve the zoning control system of marine ecological environment, delimit marine ecological space and marine development and utilization space, implement classified protection of marine ecological space such as coastal zone, bay and island, strictly restrict the occupation of natural coastline by construction projects, and comprehensively prohibit reclamation except for major national projects. In the specific implementation, we should promote the green and low-carbon development of major regional strategic platforms such as Guangzhou Nansha, Shenzhen Qianhai and Zhuhai Hengqin, innovate land and sea ecological environment governance, and form a number of innovative achievements that can be copied and popularized. Support and encourage bold innovation in Guangzhou, Shenzhen and other places, fully support the construction of Shenzhen as a global marine center city, help Guangzhou become the world's marine innovation and development capital, and help Zhuhai create a modern marine city. The plan specifies that by 2025, the proportion of areas with excellent water quality (class I and II water quality) in the coastal waters of the province will reach more than 86%. At the same time, 36 sea sections of state-controlled rivers have stabilized and eliminated inferior class V water quality, focusing on promoting the construction of 15 beautiful bays. Looking forward to 2035, the green production and life style of Guangdong coastal economic belt will be widely formed, the marine ecological environment will be fundamentally improved, and more than 80% of the key bays will be basically built into a beautiful bay with "clean water, abundant fish and gulls, and harmonious sea of people". By 2025, the Pearl River Estuary will basically complete the regulation of sewage outlets into the sea The quality of marine ecological environment is greatly affected by land-based pollution. The plan proposes to promote the accurate treatment of land-based pollution and reduce the total amount of pollutants into the sea. First of all, for sewage outlets into the sea, all coastal areas should conduct a comprehensive investigation, find out the bottom number, compile a list of sewage outlets into the sea, and implement the regulation and cancellation system. By 2025, we will basically complete the regulation of sewage outlets at the Pearl River Estuary. At the same time, we should deepen the pollution control of rivers entering the sea. By 2025, the water quality at the sea section of state-controlled rivers will be completely eliminated from inferior class v. We should also reduce the total amount of total nitrogen entering the sea, carry out the monitoring of total nitrogen and inorganic nitrogen concentration and flux of rivers entering the sea, and implement the nitrogen and phosphorus reduction project of rivers entering the sea. Coastal cities have carried out remediation of excessive total nitrogen in sewage from key nitrogen related industries, and comprehensively implemented the "one license" management of pollutant discharge permits. For marine pollution, the plan proposes to regulate and regulate beach and offshore mariculture according to law, formulate aquaculture tail water discharge standards, strengthen the discharge monitoring of tail water from industrialized and centralized continuous aquaculture ponds, and formulate and issue Guangdong aquaculture tail water discharge standards before 2023. At the same time, improve the collection and treatment facilities of ship water pollutants, improve the receiving and transfer capacity of the port, and supplement the connecting line between the municipal sewage pipe network and the wharf. Carry out comprehensive improvement of fishing port environment, and by the end of 2025, the dirty, messy and smelly phenomenon of main fishing ports will be improved. In addition, we should establish a marine ecological environment governance and supervision system. Accelerate the construction of marine ecological environment monitoring network and improve the early warning and monitoring capacity of red tide and marine garbage in key sea areas. Strengthen marine ecological monitoring, carry out remote sensing monitoring and evaluation of marine nature reserves and marine ecological protection red line, and gradually carry out marine greenhouse gas and marine carbon sink monitoring. 8000 hectares of mangroves will be built and repaired The plan also emphasizes marine ecological protection and restoration, protecting marine biodiversity and improving the quality and stability of marine ecosystems. We should build a strong marine ecological security barrier, strengthen the protection of marine biodiversity and its habitat, enhance the role of Guangdong coastal wetlands as an important stop and wintering place on the East Asia Australia waterfowl migration route, and strengthen the wetland protection and restoration of important nodes of the global migratory bird migration route such as Shantou Hanjiang rongjiangkou and Shanwei Haifeng. By the end of 2025, we will comprehensively promote the construction of five marine biodiversity conservation priority areas in the sea areas of Leizhou Peninsula in Zhanjiang, Yangjiang Maoming NANPENG islands, Pearl River Estuary, Huizhou Shanwei and Chaoshan NANPENG islands. At the same time, we should implement marine ecological protection and restoration, and take classified protection and ecological restoration measures to restore mangroves according to local conditions. By the end of 2025, 8000 hectares of mangroves will be built and repaired, including 5500 hectares of mangroves and 2500 hectares of mangroves. The plan also proposes to incorporate the protection and construction of beautiful bays into the overall layout of the whole area beautiful construction of cities above the coastal prefecture level, and create a number of ecological, urban and tourism beautiful bays. We will build Dapeng Bay in Shenzhen into a model of beautiful bay, promote the construction of beautiful bays such as Qingao Bay in Shantou and Lovers Road in Zhuhai, and build a beautiful bay with national demonstration value. By the end of 2025, we will focus on promoting the construction of 15 beautiful bays, and coastal cities above prefecture level will promote the construction of beautiful bays according to local conditions.
