“…Currently, China promulgated a series of policies on urban planning and construction (Several Opinions of the CPC Central Committee and the State Council on Further Strengthening the Administration of Urban Planning and Construction, 2016 ), the construction of new types of urbanization and integrated development of urban and rural areas (Key tasks for the new type of urbanization and the integrated development of urban and rural areas by 2020, 2020 ), the construction of regional integration in the Yangtze River Delta (The Outline of the Regional Integration Development Plan for the Yangtze River Delta, 2019 ), and the construction of digital transportation (Outline of digital transportation Development Plan, 2019 ). Many researches provide design recommendations for different situations, such as urban traffic ( Shen et al, 2020 ), office building ( Shan et al, 2020 ), urban underground ( Yuan et al, 2020 ), courtyard ( Leng, Wang, & Liu, 2020 ) and ventilation system ( Han et al, 2020 ). Current design codes for cities and buildings can provide specific design recommendations based on the types of hazards, which are basically limited to human defense, earthquakes, fires, floods, etc.…”

“…Per capita ownership of UUS construction area is an important indicator to measure the level of UUS construction. [4,7,8,11,20,21] Parking underground rate (D 13 ) e ratio of urban underground parking spaces to the city's actual total parking spaces is an important indicator to measure the functional structure of UUSs and the rational allocation of infrastructure.…”

“…e research on the measurement of UUS development has a long history, including UUS construction planning, spatial planning, ecological planning, and so on. For example, the density ratio model of UUS is used to measure the density of UUS [7], the low-carbon effect of UUS [8], the sustainability evaluation of UUS [9], the geological environment analysis of UUS [10], the assessment of underground space resources [11], the vitality measurement of UUS [12], the capacity measurement of underground space [13], the accessibility measurement of UUS [14], and so on; we can see that the measurement and design of UUS include all aspects of the whole life cycle from planning to planning, from design to construction, and from management to operation and maintenance. Furthermore, since underground space does not exist independently and is often built under urban roads or urban plots, its development is related to geological characteristics [15], the land price [16], location of development projects [17], urban economic development level [11], advantage degree of UUS construction [18], connection degree with urban planning [19,20], and the development potential of UUS [21].…”

Underground space development has gradually become an organic part of China’s urban development and construction. Comprehensively developing underground space scientifically and rationally to give full play to its comprehensive benefits is the main problem faced by China’s underground space development at this stage. This research starts with the measurement of the level of urban underground space (UUS) development. This paper constructs a UUS development level measurement indicator system, which is composed of Construction of UUS (D1), urban economic development indicators (D2), and urban population development indicators (D3), which has 12 secondary indicators, and then we use entropy-TOPSIS method to quantitatively evaluate the development level of underground public space in 39 prefecture-level cities and above in my country and analyze its spatial differentiation. The results show that the urban agglomeration has the characteristics of “high-high” cluster distribution with the development level of underground space. However, the overall level of underground space development in China’s major cities is not high and there are apparent differences in the level of UUS development. In terms of spatial distribution, the sustainable development level of cities in the eastern coastal regions of China is relatively high, with towns in the central and northeastern areas ranking second and western towns and northeastern cities ranking the lowest. At the same time, we found that there is a mismatch between the underground space development index and the economic population development index in the evaluation index. Finally, some suggestions are put forward to realize the balanced development of UUS development in our country.

Transit-oriented development (TOD) is among the most feasible strategies for relieving urban issues caused by the unbalanced development of transportation and land use. This study proposes a multiobjective TOD land use design framework for the optimization of the land use layout in station catchments. Given the high density and diverse development in Chinese megacities, a planning model that considers nonlinear impacts on ridership, land use efficiency, quality of life, and the environment is constructed. The model applies fine-grained geo-big data to fill gaps in the empirical and statistical data and improve practicability. A genetic multiobjective optimization approach without reliance on objective weighting is used to generate alternative land use schemes. A metro station in Shanghai is applied as a case study. The results indicate that the proposed ridership objective outperforms the commonly used linear function, and the optimization method has superior extreme optima and convergence to baseline models. We also discuss the consistencies and conflicts in the objectives and provide a balanced land use scheme considering local policies. This work provides suggestions for sustainable urban design with coordinated land use and transportation.
