Abstract: The development and utilization of urban underground space resources is an inevitable choice of China's urbanization strategy. In this report, we first discussed various factors that affect urban underground space development in China, and analyzed the effects of these factors and the domestic demand of urban underground space resources based on current developmental status. Then we identified the influential factors using analytic hierarchy process (AHP) method from the perspective of demand for per capita underground space in different developmental stages. Through determination of future demand levels and population capacity by city size, we calculated the total population and per capita demand by city size and predicted the scales of China's underground space developments in 2030 and 2050.
