Abstract

China is a marine country,there are convenient sea passages and abundant marine resources. Make the coastal areas become densely populated, urban concentrated, and industrially dense, Gathering heavy pollution industries such as nuclear power, electronics, medicine, heavy chemicals and metallurgy. the amount of sewage discharged from urban domestic sewage, industrial and agricultural wastewater and offshore aquaculture has increased dramatically to the oceans and estuaries. COD, total phosphorus, suspended solids and ammonia nitrogen exceed the standard seriously. The ecological environment and bio-community quality of coastal coasts, estuaries and offshore wetlands are seriously degraded, lead to degradation of many marine ecosystems. The article analyzes the status quo of environmental protection in coastal industrial zones and the future trend of environmental protection, which leads to the main influencing factors of the great changes in coastal coastal, estuary and offshore ecological environment. discharge of industrial wastewater, domestic wastewater and other large amount of wastewater in industrial areas has an impact on the water quality of the sea area. Impacts on the composition and structure of marine ecosystems, using regional risk assessment technology and methods, the environmental risk and grading of coastal industrial zones are determined through source strength analysis, environmental consequence analysis, risk characterization, risk assessment and risk management. The present situation and future development trend of marine environmental monitoring and risk management are analyzed and discussed in detail. Suggestions on optimizing environmental protection measures in coastal industrial parks, integrating basic information such as risk sources and marine ecological monitoring, and strengthening risk management of offshore marine ecological environment are put forward.
