Study On The Design Strategy Of The Underground Commercial Space Landscape In The Mega City

In recent years,the exploitation of underground space in mega-cities has become an inevitable trend of land expansion.Meanwhile,the landscape gradually changes from outdoor to indoor,so more and more attention has been paid to living environment.The landscape of underground commercial space can promote three-dimensional development of mega-cities.It can combine landscape techniques and emerging technologies to improve the environment of underground commercial space,optimize the comfort and attractiveness of underground commercial space,meet the diverse needs of customers and staff,improve the popularity of underground commercial space and help the city to develop downward.This paper studies the underground commercial space of mega-cities.Firstly,through the analysis of related concepts and research of mega-cities and underground commercial space landscape,the necessity and feasibility of underground commercial space landscape are affirmed.Then,it summarizes the current research both domestic and abroad and refines the latest research viewpoints in order to provides theoretical basis for later practice.Besides,this paper studies the present situation and existing problems of underground commercial space landscape in Deji Plaza through case analysis.Finally,the corresponding strategies and design methods are put forward,the landscape design content suitable for a variety of underground commercial space types is summarized,and the landscape reconstruction design of Deji Plaza underground commercial space in Nanjing is carried out,which will provide a expansion for future landscape design of underground commercial space in mega-cities.The results show that the integration of urban ecological concept,cultural characteristics and activities into the landscape of underground commercial space can improve the landscape environment of underground commercial space,create a comfortable shopping experience for the public,expand the functional scope of underground commercial space,enrich the types of activitiesof people,and make underground commercial space a place that people are willing to accept and enjoy,and make its environment conditions more pleasant than outdoors.Under the background of the upsurge of underground space development,through the research,we found and summarized the related problems of the underground commercial space landscape of mega city and put forward the related strategies,design methods and contents,so as to provide theoretical reference for the integration of the underground commercial space into the landscape in the future,change the previous impression of the underground commercial space occlusion,poor air quality and strong commercial,and then improve the quality of the underground commercial space.At the same time,it provides landscape basis for the undeveloped underground commercial space,and finally effectively helps the mega city to achieve vertical development.
