Sustainable Development and Construction of Urban Underground Space Based on Complex Network Theory: The Case of Hongshan District, Wuhan City

Based on the prerequisites of regional development in Hongshan District, the complex network theory was applied to evaluate the development functions. The evaluation results show that the above-ground space in Hongshan District needs to meet the high demand development of residential space on the one hand and focus on improving the functions of urban green land and municipal public service land on the other. Based on determining the development direction of the above-ground space, the site selection strategy and development direction of the underground space is proposed based on the suitable parcel D1 and parcel D2 respectively. The underground space of parcel D1 is suitable for the development of a municipal public facilities system, and the underground space of parcel D2 is suitable for the development of a transportation system and underground commercial complex.
