Optimization Strategy of Underground Space Connectivity in Historical Urban Area
Historical urban areas have the dual characteristics of regional culture and life service core.Rational development and utilization of underground space in historic urban areas can effectively alleviate the contradiction between space limitation in the process of protection and development.In view of the lack of scientific overall planning and development leading to the lack of connection of underground space,enhancing the connectivity of underground space is an important starting point for the comprehensive promotion and play of the value of underground space in historic urban areas.This paper focuses on sorting out the connectivity characteristics of underground space,and proposes the connectivity optimization strategy of underground space in historic urban areas from three dimensions of"functional coupling,morphological cohesion and timing control",in an attempt to provide theoretical guidance for promoting the continuous improvement of underground space in historic urban areas.
