Abstract
The development and utilization of underground space is an effective way to solve the shortage of urban space capacity. It is also an inevitable choice for the sustainable development of urban underground space. The development and utilization of underground space in small and medium-sized cities in China started relatively late and lacked practical basis. This paper selects three representative small and medium-sized cities in east China to study the status quo, contents and achievements of underground space development and utilization, makes a comparative analysis, and puts forward the overall characteristics of underground space development and utilization in small and medium-sized cities, hoping to provide reference for the development and utilization of underground space in small and medium-sized cities in the future.
Highlights
By the beginning of 2017, China's urbanization rate had reached 57.35 percent, while the urbanization levels of Shanghai, Jiangsu, Zhejiang, Fujian and Shandong in eastern China were 87.6 percent, 67.7 percent, 67 percent, 63.60 percent and 59.02 percent, respectively, all higher than the Chinese average
Zhangjiagang city and Shaoxing city are representative cities of small and medium-sized cities in east China that have achieved some achievements in underground space development relatively early, so they are selected as cases
Through the content and analysis of underground space development and utilization in Kunshan, Zhangjiagang and Shaoxing, this paper summarizes the following characteristics of underground space development and utilization in small and medium-sized cities in east China
Summary
By the beginning of 2017, China's urbanization rate had reached 57.35 percent, while the urbanization levels of Shanghai, Jiangsu, Zhejiang, Fujian and Shandong in eastern China were 87.6 percent, 67.7 percent, 67 percent, 63.60 percent and 59.02 percent, respectively, all higher than the Chinese average. With the acceleration of the pace of urban construction, the air and ground space tend to be saturated, which makes a series of "urban diseases" such as resource shortage, environmental quality decline and traffic congestion in east China become increasingly serious. Rational development and utilization of underground space will be an effective measure to solve the problems of "human-land contradiction" and "urban disease" in the process of urban development. As the main force to promote urban development in China, small and medium-sized cities play an increasingly prominent role in China's economic and social development and urbanization process. Rational development and utilization of its underground space is the basis of promoting sustainable urban development in China. Based on the research on the development and utilization of underground space in typical small and medium-sized cities in east China, it is of great significance to solve the problems in urban development, such as traffic congestion, insufficient parking space, and difficulties in infrastructure maintenance and transformation, and to the development and utilization of underground space in small and medium-sized cities in China
