Research on the Open Space Design of Public Buildings under the Background of ‘High-density City’:Reporting from Beijing,Shanghai,GuangZhou,Shenzhen,Hongkong

The'high-density problem'that caused by the expansion of population has been an important social issue,and it must consider the basic environmental quality while appealing for space for survival.As one of the means for alleviating urban problems,opening architectural space has very promising prospects.Therefore,on the background of the rapid developmental typical domestic cities,selecting public buildings that are easy to innovate as the starting point,by means of collecting and collating a large amount of data,comparing and summarizing case studies of open spaces,analyze their practical significance,current status issues and spatial types.In the future,it will provide a theoretical basis for researching the new architectural open space model in the high-density environment and looking forward to the future city.
