摘要
Urban underground public space has a synergistic effect with its surrounding urban aboveground functions or facilities,which reflects the complementarity between underground functions and urban functions.The research analyses the degree of integration through the case study of urban aboveground space and underground space in China.The research method of this paper will give different evaluation criteria to public transport and public space and the influencing factors of space integration.The indicators of public transport include the number of subway lines and underground parking spaces.The evaluation standard of public space is the area of underground space and the number of floors of underground space.The subway entrance and exits are selected as the evaluation index for the aboveground and underground transition space.Through the specific analysis of 7 selected cases,it provides arguments for the research.The average rent in the case is taken as the dependent variable.Through the regression model,the influencing factors of the integration of aboveground and underground space are determined.The purpose of the study is to explore the influencing factors of the integration of aboveground space and underground space,and how to optimize the integration of aboveground and underground space.
