Study On The Rationality Of Urban Planning With The Application Of Environmental Impact Assessment

With the rapid development of industrialization, Urbanization has beendeveloped rapidly. It not only improved the quality of people’s life, but also got thecontradiction between economic development and urban environment a moreprominent. The city wants to have a sustainable development, wants to benefitfuture generations, and must have a reasonable planning and development. Takinginto account the economic, social and environmental benefits in the planningprocess, take the Environmental impact assessment into urban planningdecision-making process. From this for pollution source control avoid go "firstpollution, after management"--has an important role. This for the reasonable layouthaving the minimum industrial pollution influence to city, creating good livingenvironment, promoting the healthy development of urban sustainabledevelopment strategy, has the extremely vital significance. Therefore, combinedwith urban planning and environmental impact assessment is an important way forsustainable urban development planning.Although China promulgated the People’s Republic of China onEnvironmental Impact Assessment Law, provides a plan to expand theenvironmental impact assessment. But for all the planned projects are a generaldescription, urban planning working on the environmental protection has problems.EIA of urban planning in China has developed five years, but related to urbanplanning theory and methodology of the EIA are not perfect, there are still manyproblems in practical application.In view of this, this article first analyzed the characteristics of urban planningand the planning and EIA, summarized the urban planning EIA of universality, complexity, macro and uncertain characteristics, analyzed The problems of urbanplanning EIA, such as: the combination degree of planning EIA was not enough,the method and theory of application was immature, the main body of theevaluation was uncertainty, the utility of the evaluation results, etc. The paperfocused on the combination of urban planning and planning environmental impactassessment study. Including Combining work procedures、the line of work、themain participation body and so on. In the city plan of EIA evaluation content, putsforward the environmental impact of the change in the past in the evaluation of thepassive "negative" of the environmental impact assessment of status, advocate theinitiative "positive" environmental impact of construction. This will help toimprove the quality of the urban environment and enhance the city people’s qualityof life. According to the combining work procedures, the paper put forwardWOAD comprehensive analysis method; and then, with the PEIA, the paperanalysis evaluation the rationality of the urban planning from the five aspects.About how to make the comprehensive decision-making, get a optimizing choicefrom many plans, This paper proposed a decision method for urban planningEIA,it’s data envelopment (DEA); Finally Combined with the planning of thehigh-tech zone of Weinan cases were analyzed and explained.The result of this paper will further enrich and improve the environmentalassessment of urban planning theory and technical methods, reference andguidance for sustainable urban development planning.
