Research On Public Space And Building Density In The City New-built Central Business District

With the rapid development of China’s society and economy, more and more cityput forward the assumption of constructing Central Business District, in the city"polar" where has dense population, capital concentration and high-rise buildings, thepublic space has been paid more and more attention. Besides, the building density, asthe important indicator for the intensity of land exploitation has all kinds ofconnections with the creation of public space. Chinese Communist Party CentralCommittee clearly put forward that we should build environment-friendly,resource-saving society. How to balance the relationship between the building densityand public space, become the key to the city new-built Central Business District topractice environment-friendly and resource-saving society. Through the analysis oftypical cases, and borrowing ideas from correlation theory of building densityresearch and practical cases of creating public space at home and abroad, Attempts toexplore the relationship between the public space of plastic and building density,building density control model and put forward the corresponding and appropriateindex value. It has certain reference significance for creation of the public space in ournew city business center area in the future.Firstly, the research studies the domestic and foreign new research of buildingdensity in the city new-built Central Business District, and then analyzes thedevelopment progression and basic characteristics of China’s central business district.Through the investigation of the3typical cases of the city new-built Central BusinessDistrict, we learn about the current situation of development and construction of thehigh-rise and low density in our central business district, and then analyze the cause ofhigh-rise and low-density development mode and the present situation of this mode.Secondly, this paper research Human activities, human needs and factors of creating agood public space in the central business district, then discusses the impact ofbuilding density to the creation public space, and through the study of traditionalsmall scale public space, puts forward control measures of building density regionalcentralized. Firstly the dissertation analyzes the advantages of regional concentrationequilibrium model; secondly, analyzes the feasibility of regional concentrationequilibrium models in national policy, economic, practical aspects; finally, proposesthe goal and principle of building density area concentrated balanced mode control,including the intensive use of land in principle, integrity principle, the principle of operation. On this basis, this paper further discusses the concrete measures tobalance mode good public space shaping regional focus, including traffic organization,space scale and weary interface control, the layout of the building good public spaceshape as the basis, and on the basis of good public space shaping the optimalconditions of building density index of different construction the layout of thebuilding density, good public space creation under the appropriate value obtained bymeans of verification.This research is to discuss our new district building density index to control thebusiness center, is just the research on the issue of discussion, is not a decision oraction research on China’s new construction, central business district has a certainsignificance.
