☆ 2005 the city's marine environmental monitoring results show that: the near-shore sea area of seriously polluted sea area of 4,131 square kilometers, the area of moderately polluted sea area of 2,396 square kilometers, Zhoushan sea area of the overall quality of the marine environment similar to that of last year, but the area of seriously polluted sea area has declined. Seawater in the main exceeded the standard factor is nutrient salts, part of the station petroleum class slightly exceeded the standard.
☆ In 2005, the quality of surface sediments in Zhoushan's near-shore waters was good, except for copper, a heavy metal, which slightly exceeded the standard in some stations, the rest of the indicators were in line with the quality standard of a class of marine sediments.
☆In 2005, the sanitary quality of economic shellfish in Zhoushan City's coastal areas was quite good; in the economic shellfish (mussels, razor clams, arkshells, oysters, etc.) sampled for testing, except for a slight residual of the heavy metals lead, cadmium, and DDTs, the rest of the indicators conformed to a class of marine biological quality standards.
☆ Red tide disasters occur frequently. 11 red tides occurred in 2005***, with a cumulative area of more than 10,000 square kilometers.
With the development of Zhoushan City's economy, the environmental quality of near-shore and offshore waters is not optimistic, and the amount of various pollutants discharged into the sea will not be significantly reduced in the near future. Therefore, it is necessary to strengthen the marine environmental monitoring and remediation efforts in the sea area under the jurisdiction of Zhoushan City, so as to serve the government departments at all levels in formulating marine environmental management policies, determining marine environmental management objectives, mitigating marine disasters and adjusting economic structure. At the same time, it is also hoped that government departments at all levels and the public will continue to pay close attention to the state of the marine environment in Zhoushan City, protect the marine environment while developing and utilizing marine resources, ensure the stability, diversity and integrity of the marine ecosystem, and ensure the sustainable use of marine resources and the sustainable development of the marine economy.

In addition, in order to release seedlings can be successful, in the city's waters to set up a 3600km2 of temporary breeding and release protection zone, the provisions of the May 15 to September 15 to prohibit the impact on the resources of the operation mode of operation. Through the work of stocking and releasing and the setting of the temporary stocking and releasing protection zone, the fishery resources in Zhoushan waters have been partially restored.
5.4 Recycling of Used Batteries
In 2005, Zhoushan City and Shengsi County Marine and Fishery Departments further initiated the recycling of used batteries. Together with Zhoushan Marine Environment Monitoring Center, they set up waste battery recycling bins at the docks of key townships in Shengsi County's fishery industry and near schools and communities, and took measures such as increasing publicity and giving certain incentives to mobilize fishermen to recycle waste batteries, so that waste battery recycling work has been carried out effectively. At present, nine fixed waste battery recycling boxes have been set up in Wulong and Caiyuan in Shengsi, and more than 30,000 batteries have been recycled.
5.5 Seasonal Fishing Moratorium
During the 2005 seasonal fishing moratorium, Zhoushan City's marine and fishery departments at all levels strengthened sea and land linkage law enforcement, strictly prevented and investigated, strictly controlled and heavily punished, and realized zero violation of the city's seasonal fishing moratorium. At the same time, according to the "2005 fishing moratorium before the opening of the law enforcement management program", the implementation of specific actions, successfully completed the scheduled plan.
5.6 Fishermen's conversion
2005 is the fourth year of fishermen's conversion, Zhoushan City, the marine and fisheries departments vigorously implement the fishermen's conversion project, the annual conversion of fishermen in 2008, scrapping and dismantling of 323 fishing boats, by the end of 2005 Zhoushan City **** conversion of fishermen totaled 7,674, scrapping of 1,703 fishing boats, the surrender of horsepower indicators 182,000 kilowatts, ranking first among prefecture-level cities in China. The advancement of fishermen's conversion has effectively reduced the intensity of marine fishing.
5.7 Eco-farming
The marine and fishery authorities in Zhoushan City have increased their efforts in eco-farming, promoted standardized farming and scientific farming modes, and actively implemented the construction of the "Three Belts and One Area" eco-farming demonstration area. The city's advantageous industrial belt base all through the pollution-free base certification, new pollution-free base area of 8085 acres.
6. Supervision and management of marine ecological environment
6.1 Relevant local laws and regulations as well as the construction of supporting systems
In 2005, Zhoushan City Bureau of Oceans and Fisheries completed the preparation of Zhoushan City Marine Ecological Environmental Protection and Construction Plan and Zhoushan Construction of China's first-class modernized fishery base planning program, and now the two plans have been through the validation, and reported to the municipal government for approval. Approval.
6.2 Supervision and management of marine environment of sea-related engineering construction projects
In order to implement the Regulations on Marine Environmental Protection of Zhejiang Province, to promote the environmental supervision and management of sea-related engineering construction projects in the cities and counties, to standardize the management of environmental assessment of sea-related projects, to strictly review (approve) the work of sea-related engineering projects, to improve and perfect the system of review and approval, and to carry out strict checking on the environmental impact assessment report, and to review and approve the major environmental impact assessment reports. Strictly check the environmental impact assessment reports and carry out follow-up surveillance and monitoring of major sea-related construction projects. 2005 has dealt with illegal sea sand mining and illegal sea-related construction projects, such as investigating and dealing with illegal sand mining near Yushan Island in Daishan and illegal reclamation on Pamphlet Island. In the case of the Yongyue Shipyard's illegal blowing up of cofferdams and dumping of waste, it was ordered to make up for the formalities, and so on. In addition, it also dealt with projects that clearly violated the marine functional zoning.
6.3 Fishery Law Enforcement
In terms of environmental management of fishery waters, we have seized the two important links of fishing ports and fishing vessels, and combined them with fishery safety inspections to effectively manage fishery waters and fishing vessels. Strengthen publicity and education to provide fishermen's awareness of environmental protection; strengthen the anti-fouling management of ocean-going fishing vessels, which are equipped with oil and sewage separation devices as required to protect the marine environment; and increase the supervision and inspection of marine ports to investigate and deal with illegal discharges.
7. Countermeasures and Suggestions
In view of the quality of marine environment in Zhoushan City in 2005, it is suggested as follows:
Continuing to strengthen the supervision and monitoring of the land-based outfalls into the sea, the supervision and monitoring of the selected key land-based outfalls in 2005 showed that the environmental quality of the outfalls and their neighboring waters should not be neglected, and that the phenomena of exceeding the standard and violating the rules and regulations of the discharges are more serious. Therefore, we should continue to strengthen the supervision and monitoring of the city's land-based outfalls into the sea and the supervision and management of sewage disposal units, new and expansion projects must be strictly carried out environmental impact assessment, and effectively achieve the "three simultaneous"; at the same time, the relevant departments should strengthen cooperation and increase the control and management of pollutants entering the sea from land-based sources, especially marine oil pollution. The increasingly serious situation, to strengthen the control of oil pollution sources.
Strengthen the total amount of pollutants control and enterprise sewage discharge. Strengthening and implementation of the total amount of pollutants control and enterprise sewage discharge, should be the standard discharge of industrial enterprises and the environmental capacity of the polluted sea area is closely linked to the outfalls should be strictly implemented in the total amount of pollutants control of the pollutant outfalls and the environmental capacity under the awareness of the standard discharge, Zhoushan "strong marine economy" and "eco-city". The "ecological city" construction to make a positive contribution.
Strengthening of marine environmental protection and surveillance monitoring. In order to do a better job of the city's marine environmental protection, 2006 should continue to strengthen the city's marine environmental protection and surveillance monitoring work, especially in the near-shore sea areas on the basis of trend monitoring, focusing on strengthening the marine ecological environment of the sensitive areas, the key harbors and bays, the key polluted areas, such as sewage outfalls, such as the surveillance monitoring.
Strengthen the protection of key marine protected areas. Promote the construction process of Zhejiang Shengsi Ma'an Lidao Marine Special Protected Area and Zhejiang Putuo Zhongjieshan Lidao Marine Special Protected Area, and incorporate the protection of this protected area into the legalization and proceduralization as soon as possible.
Continuing to strengthen the surveillance and monitoring of marine pollution events, red tides, storm surges and other marine disasters. Carry out and improve the monitoring and assessment of marine defacement events, and further improve the early warning and forecasting of marine natural disasters such as red tides, storm surges and catastrophic waves. Improve the marine disaster emergency response system and measures, and actively carry out relevant marine disaster technology research to effectively reduce marine disaster damage.
Strengthen the supervision of sea-related projects such as coastal engineering and marine dumping areas. The environmental impact assessment of sea-related projects is carried out in accordance with the law, with scientific proof and strict approval, and the environmental impact tracking and surveillance monitoring of sea-related projects is actively carried out.
Strengthen the construction of marine monitoring and forecasting system. In response to the increase in marine disasters, marine accidents and emergencies, and the trend of increasing marine pollution, marine monitoring and forecasting is more important. At present, the capacity and means of marine monitoring and forecasting are far from adapting to the needs of reality. Therefore, to increase investment, as soon as possible to form a municipal marine environment monitoring and forecasting center as the hub, to the county and district-level station as the backbone, including the three islands, including the layout of the city's marine environment monitoring and forecasting system is reasonable and more complete.
