Research On Sea-land Integrated Regulation And Controlling Of Harmony Development Of Economy And Environment In Offshore Area

The coastal zone is the cradle of mankind, the center of politics .economy and culture. Yet it's weak ecology environment is being damaged for population increasing, fast development of economy and out-of -order exploitation. Ecology sustaining is the base and economy sustaining is the term of social sustaining development. So it is signality to research the harmonious development of economy and environment in coastal zone for the social sustaining development.The pollution of the offshore maritime area is the main ecology environment problem and has become main throat of jar" of sustaining development of coastal zone. The paper briefly sums up the research situation of economy and environment harmonious development on coastal zone in china or the abroad and analyzes the ecology environment problem that caused by urbanization and industrialization. Then probes into the present situation and the mechanism of pollution and the function of sea-land integrated for the pollution of the offshore sea area. The research on the offshore maritime area pollution still stays on the concepts and qualitative analysis, the quantitative analysis is seldom, so great base work , theory research , models together with methods need to be resolved. Proposes the research contents that we must carry on the sea-land integrated regulation based on the condition of the pollution in offshore maritime area. The major contents and research results are as follows:(1) Reviews the feature of economy development and chief environment problems aroused in the procession of urbanization and industrialization for example of coastal zone in DaLian. Analyzes the integrated environment of DaLian with the multi-level multiple objective fuzzy decision pattern, the result show that water environment pollution is pivotal to the coastal zone in Dalian. So the evolution and effect elements of water environment quality of the coastal maritime area are researched adopting integrating means of the fuzzy recognition pattern and multi-regression model, results show that the water environment quality in DaLian bay is the worst and near to third level and has deteriorates tendency one by one and the main effect element of water environment were the waste water discharges quantity and waste water treatment rate and per capital output of the third industrial.(2) The relationship between the water environment pollution and economic growth is researched first. the results show that mineral oil concentration and per capita GDP presents to sell up "the U character relationship, in that mineral oil concentration will start decreasing when per capita GDP is 15000 Yuan but the waste water discharge, living-water consumption, phosphate and COD concentration will increase with the increase of the per capita GDP. The indexes of economy and environment sustaining development are proposed and the harmonious development of water environment and social economy of DaLian were analyzed adopting theprincipal components analysis together with fuzzy anigh degree means, the results show that economy development speed were faster than that of the water environment deteriorates, the relationship between water environment and economy is basic harmonious in recent years (economy development is on the base of water environment being living deteriorates somewhat) .(3) DYNAMO is ideal means to handle high rank, nonlinearity, mulriple feedback and complex large-scale systems movement .The paper establishes casual relationship chart of regulating the offshore area pollution based on analysis the affect elements of water environment, then establishes stream velocity and gross variable equation, finally utilizes SD pattern to regulate and control, three development schemes are obtained in that conventional trend, quality-standing and harmony development scheme. Finally, we trust that the third scheme is best. So we know that to make DaLian sustaining development only to improve the water environment.(4) The paper proposes fuzzy decision pattern bases composed weight together with in...
