Research On Supply And Demand Characteristics And Public Potential Of Open Space In High-density Blocks In Guangzhou Based On Multi Source Data

With the development of China’s economic level and the transformation of the main social contradictions,the urban development mode has also changed from paying attention to the incremental growth of speed to the improvement of quality.Today,public open space plays a more and more important role in public daily life.However,in big cities,especially in high-density central urban areas,the number and scale of public open space are extremely scarce.On the premise of not increasing construction land,the new open space needs to tap the potential from all kinds of ancillary land.Therefore,how to scientifically and efficiently identify the supply and demand characteristics of ancillary space and screen the public ancillary space has gradually aroused the thinking of urban builders.This study selects the high-density central urban area of Guangzhou as the research object of typical high-density urban area.Since the 1990 s,the central urban area of Guangzhou has carried out management and control construction under the guidance of urban design guidance.In this process,many ancillary open spaces have been produced.However,due to insufficient management and control,the level of publicity of such spaces is uneven.This thesis summarizes the excellent experience at home and abroad.Taking the core area of Zhujiang New Town in CBD as an example,this thesis puts forward a set of open space supply and demand matching method to adapt to the information age,and then applies it to the whole high-density central urban area to identify the publicity potential of each plot,and establish a potential tapping method of affiliated open space suitable for domestic high-density cities,so as to provide reference for the relevant research of other cities or regions in China.This thesis is mainly divided into four parts.The first part is the first and second chapters.Based on the theoretical and practical background and relevant research,it expounds the definition and related terms and concepts of open space,and summarizes the publicity strategies of open space at home and abroad;The second part is the third and fourth chapters.Taking the core area of Zhujiang New Town as an example,collect multi-source big data and identify the supply and demand matching of its open space from the two levels of spatial distribution and site construction;The third part is the fifth chapter,which identifies the distribution characteristics of the affiliated open space in the high-density central urban area of Guangzhou based on various indicators,and identifies the potential of land mass publicity based on the supply-demand matching of index data;The fourth part is the sixth chapter,which puts forward the publicity strategy of affiliated open space for high-density urban areas,in order to provide reference for the planning and research of high-density urban open space in major cities in China.
