Research On Ecological Function Zoning Of Dalian

The development of the regional strategy has turned to how to coordinate the new period of development.,as the rapid development of industrialization.The construction of ecological function regionalization is a new model for the implementation of integrated regional development.How to make good use of the"ecological environment" has gradually become a research hotspot.Therefore,only further research on the ecological function regionalization,to provide support for government decision-making is an important guiding value for the sustainable development of the social economy.The research on urban ecological function regionalization has been carried out in various parts of China.Based on the above situation,this paper summarizes and analyzes the research results of ecological function regionalization in domestic and overseas.On the basis of determining the research objectives of Dalian's ecological function regionalization,the research methods of spatial analysis,analytic hierarchy process,statistical charting,and summarizing methods,analyzes the present situation of ecological environment in Dalian,summarizes the general situation of the natural environment in Dalian,and tease out the processes of the ecological environment in Dalian and current situation of the resources and environment.Then,comprehensive domestic and foreign research results and methods of ecological function regionalization,the paper determines the ecological function regionalization in Dalian research objectives and research methods,based on spatial analysis,analytic hierarchy process(ahp),statistical chart method,sum up method and so on,on the basis of research methods,analyze the present situation of ecological environment in Dalian,summarizes the general situation of the natural environment in Dalian.Then,the present situation of the ecological evolution in the natural environment in Dalian,resources and environment,parity,combing with the research on the aspects such as climate,river system in Dalian,geology,water resources,forest resources,mineral resources and so on the present situation of the ecological factors,summed up the general situation of the ecological system of Dalian.And then,through to the Dalian area within the scope of the ecological and environmental indicators for analysis and evaluation,including ecological service function value index and ecological sensitivity index 2 primary importance evaluation index and water conservation and water,biodiversity maintenance and protection of importance evaluation importance,nature reserves evaluation,acid rain,perceptual evaluation,evaluation of soil erosion sensitivity five secondary indexes.The ecological service function and ecological sensitivity evaluation of Dalian city were evaluated by means of the comprehensive evaluation method of ecological system and related research contents.Finally,according to the content of the comprehensive evaluation of the ecological system,combining the objective demand of Dalian city development,combined with domestic ecological function zoning advanced concepts,has carried on the ecological function regionalization of Dalian,it is divided into two levels of ecological function zoning.Among them,the first level of ecological functional zoning is divided into four categories:natural ecological conservation area,ecological functional reserve,ecological buffer zone and urban development zone.The second level is divided into four categories:forbidding access areas,restricting access areas,key access areas,and optimizing access areas.The total area of Dalian city is divided into four main functional zones,11 small ecological functional zones and ecological functional zoning maps.The main ecological function of each region is located,and the overall ecological service function of Dalian is integrated.It aims to provide references for future development of Dalian.
