The Research On Development Zone Space Layout Planning In JiXi County Of Economic Based On The Scenario Planning

For over 30 years of reform and opening-up,C hina industrial economy fast development,the development zone has become the main carrier of urban industrial economy,its importance in the planning of urban construction in our country is becoming more and more prominent.The development of the development zone space layout,directly affects the economic development of development zone,at the same time,it brings to the city and the region's economic development impact.In recent years,in order to realize the pattern of economic development from scale speed type to quality efficiency of extensive growth and intensive growth,the economic development of our country into a period of comprehensive reform,in this period of economic operation will encounter ma ny risks,the corresponding development zone development environment factors of uncertainty will also increase,this increases the space layout planning of risk.Various requirements in the face of such environmental risks and challenges,space layout plann ing of development zone will need to offer more suitable for the future development strategy and scheme to promote urban development.Because of the traditional development zone space layout planning method of era background and working procedures such as various limitations,have been unable to meet the demand of development zone development highly uncertain environment.This article through to the development of uncertainty,the traditional development zone development environment space layout planning and the analysis of the scenario planning related research,explore the development zone in the layout space,and the necessity and the possibility of using scenario planning,look for ways to scenario planning steps and the development space layout planning step 4 of the combining site,and then combined with scenario planning method is applied in the field of urban planning and design work process,innovation generation method based on scenario planning development space layout planning and operation method(five steps).Main research parts in jixi county development zone in anhui province as an example,combining with the development of jixi county development zone environment external demand,from the situation foundation,determine the focal point and key factor analysis,inductive setting scheme,rich scene simulation solutions,evaluation monitoring scene simulation implementation of five levels of scenario planning method in the application of jixi county development zone space layout planning research.In jixi county development zone,this paper puts forward three kinds of possible future scenarios,namely the scene A: dominant ecological tourism development model(in the steady development or environmental priority intention and under the condition of plenty of funds,eco-tourism development function is prominent scenario).Scenario B: industry leading development model(under steady intention or emphasis on the real economy,under the two financial conditions,outstanding manufacturing priority setting).Situation C : balanced comprehensive development model(in the case of environmental priority function is outstanding manufacturing,or in the emphasis on the real economy at the same time highlight the ecological tourism situation).Then analysis and put forward principles under each scenario simulation project concept,assumptions,and situational inference;Through the implementation of specific space layout design,rich scene simulation scheme of land layout scheme of possible space,to evaluate three scenarios simulation scheme,choose the dominant scheme(the scheme)can be realized.Because the future is uncertain,in view of jixi county development zone C some scene simulation project monitor index,so that the city managers in the process of planning to get a grip on reality changes,flexible use.Finally,by jixi county development zone space layout planning in the development zone in the layout space reflection points should be paid attention to when using scenario planning method.
