Urban Dwelling Spatial Layout Optimization Based On Social Stratum Structure

Urban dwelling layout is a serious problem which is closely related to urbanizationprocess, resource environments, sustainable development and harmonious societyconstruction in China. In consider of Chinese harmonious development of nature,society, and economy in the future, this paper expatiates how to optimize urbandwelling spatial layout based on social stratum structure.It makes an analysis of the evolution mechanism of urban living space and theclass structure by using evolution theory, and also it analyzes the nature of urbanliving space "system"、organization and characteristics. It establishes an organizationalsystem model to analyze the phenomenon like the closing of the urban living spaceclass structure and other evolutionary phenomenon. It also explains several mechanismof urban living space, such as:“it is difficult to achieve the designed goal of the system“directly”,etc. This paper also makes a research on the harmonious evaluation of theurban living space class structure and the relations between social selection with the useof the harmony theory. It builds a model of the multi-level cross-class urban livingspace structure for the future of our country.By analyzing the situation and the future trends of the Chinese social structure, itdefines the "fundamental factors" and "long-term dominant factors" which have a greatimpact on the social class structure. Furthermore, it suggests a solution that is to makethe middle class as a breakthrough point when forecasting the long-term trends of thesocial class structure. It also estimates all the sectors of the city’s population distributionin China till2050.With the use of the long-term estimating method and also the sub-class method ofthe average residential situations, this paper makes an estimation of average stratumsubdivision number for the the total incremental of urban housing construction till2050.It selects Kangju standards as the long-term standards for our city’s residential landthrough the job of analysis and evaluation of the relations between arable land andpopulation in the future. Based on this standard, it estimates the average stratumsubdivision number.It determines the ideal urban form-circle form as the basic structure of the cityand divides the development types of the state’s main cities on the basis of the futuresituation. Based on Based on the remaining social welfare function and the function of the value of harmony, it forms a better model of the urban living space class structure.By using of such a model, this paper makes a simulation optimization. of the layout ofliving space for the3-8cities.Some innovative have been drawn during the research process, such as the basicalsystems like the law on the Protection of layout of urban living space and socialinterests; new construction standard for the3-8、2-6and1-4cities; defining theeverlasting concept of urban housing construction; designing the residentialanti-filtering policy; making policy recommendations for the corresponding domesticprices, financial and social security.
