Studies On “interval Form” Of Residential Land Plot Ratio In Nanan Guan Qiao’s Township

Urbanization process in China has entered the critical stage, gradually changing from the macro spatial pattern of the town, from the micro deep influence the residents way of life, in the process of urbanization, how to through the way of planning and design of land development intensity control, reasonable guide the orderly expansion of urban scale, layout optimization and adjustment of urban land, promoting land resource utilization efficiency and intensification, is the urban and rural planning workers should consider the problem. The planner controlled technical level, mainly through the implementation of the control volume rate rules to implement the mandatory index of construction land development intensity control, thus regulating the amount of urban housing development and construction, and the current research and practice are mostly based on land development intensity control in big cities, small cities and towns residential land plot ratio control is lack of theoretical guidance, this article is in view of the current small town residential land plot ratio of assignment to the needs of the guiding theory, combined with the author in under the guidance of a mentor in nanan Guan Qiao Town center township controlling detailed planning and engineering design and research on the transverse.The article begins with the clear "small town", "residential land", "volume" and "plot ratio range" the object of study, on the basis of the concept of summarizing the current volume rate control theory research achievements at home and abroad and the direction, summarized the developed countries and our country Hong Kong, shenzhen, Shanghai, guangzhou and other cities of plot ratio control practice of technology system and nutrition for nanan Guan Qiao Town center from the township of residential land plot ratio control research. In order to further clarify the essential theoretical foundation of the residential land cubage, papers on the IV technical factors of affect the residential land, land condition, some researches on the planning and design, construction monomer respectively, including land use condition factors from land use land for size, shape, toward the three Angle analysis, planning and design factors from planning to the model structure, layout, sunshine three Angle analysis, single building factors from the deep and wide, tall, residential housing layer three Angle analysis, understand the planner controlled the elements of the technical aspects of the role for residential land cubage rate mechanism.Core section of the essay in the first place of the status quo of Guan Qiao Town overview, introduces the residential land development planning guidance, understand the research base of the dilemma of development and potential, problems and opportunities, in order to better carry out targeted research, and based on plot ratio under the market economy caused by the current situation of tripartite benefit gambling puts forward the township Guan Qiao Town center residential land plot ratio the starting point of the assignment. Second residential land in the center of the Guan Qiao Town township a total construction area of forecast, on the basis of composite weighting method using Delphi method and selection of evaluation factors, at the level of analytic hierarchy process(ahp) in the value of land using impact factor weights assignment, based on the GIS software ring buffer analysis of single factor and multiple factors of raster overlay analysis to build township residential land partition density, total function is introduced and through the development and the relationship between partition to implement benchmark volume rate range for each plot. And then through the research of the relationship between real estate development costs and benefits, research Guan Qiao Town center township benchmark land prices, real estate development costs, solving the different volume rate corresponding to different residential type combination can gain the proportion of the investment profit margin and build volume rate and investment profit margin between the model curve, then constant function with a simulated intercept method "Y = industry benchmark return on investment" on the interception of economic volume rate range. Finally Guan Qiao Town center township in block A, for example research without considering the negative external effect under the premise of its neighboring area can hold the limits of environmental capacity, adopt the method of isolating single factor, respectively and the population density, rizhao restrictions, public green space, number of parking space, municipal facilities supply restrictions under five elements define the limits of volume rate range, again through the five elements of the limit capacity of intersection operation and the plot of A comprehensive range limit volume rate.Conclusion put forward by the benchmark plot ratio range, economic volume rate range, and limit volume ratio intersection operation range three build nanan Guan Qiao Town center township residential land comprehensive volume rate range of technical route, then the current township Guan Qiao Town center has built residential plot ratio control evaluation and reflection on the above model, and finally build residential land plot ratio range computing platform, at the same time points out the technical route of deficiency, need combined with practice, feedback and deepening to more reasonable and effective control of small town residential land plot ratio.
