A Study On The Publicity Of Three Dimensional Public Space In High Density Cities

Under the background of economic globalization,capital,information,manpower,energy and industry are highly concentrated in cities and some regions,and highly concentrated resources have effectively promoted the rapid development of cities.This process inevitably brings about the high-density development of cities,and it also promotes large cities transformate from two-dimensional plane growth to three-dimensional construction,including the three-dimensional development of public space,which plays an important role in people`s daily life.However,the particularity of three-dimensional urban design also means that threedimensional public space is facing more complex public problems.Therefore,this paper takes three-dimensional public space as the research object,evaluates its publicity and summarizes the problems.Firstly,tease out the concepts and related issues of high-density city,three-dimensional public space and space publicity,and the research progress of three-dimensional public space publicity at home and abroad is summarized.On this basis,combined with China's social,cultural context and legal system,the composition dimensions and defining characteristics of urban space publicity applicable to China are determined.After that,I summarize the special influence factors of three-dimensional public space on public life,including vertical location and vertical traffic,and establishes the evaluation model of three-dimensional public space publicity.Secondly,Shenzhen,the first city to propose stock planning,was selected as the research object.This paper briefly introduces the construction of three-dimensional public space in Shenzhen,and select thirteen typical three-dimensional public spaces as representatives to carry out public evaluation and excavate the existing problems,which mainly include six specific aspects: lack of adaptability of space function,lack of diversity of space design,privatization of operation and management,and low level of public awareness.Thereafter,aiming at the problems of Shenzhen's three-dimensional public space,this paper puts forward four optimization strategies for the three-dimensional public space from four aspects: planning policy,urban design,management subject and use subject.Finally,on the basis of systematically combing the relevant research and evaluation methods,this paper reviews and summarizes the research progress of the three-dimensional public space publicity,explores the weak links in the current research,and puts forward the research directions that should be paid close attention to in the future,in order to provide theoretical support for the further research of the three-dimensional public space.
