During the Tenth Five-Year Plan \The development of marine fisheries, offshore oil, coastal tourism, marine transport, salt and salt chemical marine industry has made remarkable achievements. The same time, marine engineering and marine scientific research capabilities significantly improve; marine resources and environmental management, and environmental monitoring, forecasting and other public service level to a new level. However, the prevention and control of marine pollution, protection of the marine ecological environment is still heavy marine disaster prevention and mitigation, and maintain the sustainable and healthy development of the coastal areas of socio-economic task is still arduous. Coastal waters of Dongying City in 2001 and 2005 years by satisfied rivers and trunk sewers and sewage discharge is about 700 million tons, the years then Naru Hai pollutants total of about 40 million tons, the main pollutant chemical oxygen demand, according to the statistics. BOD, phenol, petroleum, ammonia nitrogen, phosphate. In recent years, with the Yellow River to the reduction of water and the marine industry's rapid development of the economy, the marine ecosystem of the Yellow River Estuary change benthic diversity the marine economy biological Spawning gradually disappear, the water nutrient imbalances and eutrophication, degradation of estuarine spawning grounds biomes structural abnormalities appeared in succession, regional marine ecological environment quality is not optimistic. In this paper, a detailed analysis, summarize Dongying City terrigenous major pollutants into the sea outfall ammonia, oil, COD, hexavalent chromium, excessive pollutants as ammonia, petroleum, COD, hexavalent chromium pollution is more serious. Can be seen that the discharge of pollutants by industrial activities on marine pollution caused by max. In addition, living sewage, and also give the ocean polluted to varying degrees, to strengthen the control of land-based sources into the sea pollution sources, increase the sewage treatment facilities, and protecting the marine environment is particularly urgent and important. To strengthen the enforcement of law system to improve its marine environment; national awareness, establish new marine values; strengthen Dongying waters surrounding Environmental Protection; basis for capacity building to strengthen the protection of the marine environment; enterprise sewage constraint mechanism must be established; strengthen international cooperation in marine science and technology, comprehensive the basic connotation and the main characteristics of a sustainable marine development and marine protected, described some of the lessons learned in the protection of the marine environment, a more comprehensive analysis and suggestions on the protection of the marine environment and marine resources development in Dongying City.
