General Architecture of Sustainable Urban Spatial Development Model Based on Smart Cities

With the rapid growth of China's national economy and urbanization, the use of urban space in China has developed greatly. At the same time, there are also many problems, the relationship between urban space planning and ground planning is not coordinated enough, and there are certain contradictions in the development of different levels of space, which will inevitably affect the sustainable development of urban space in China in the long run. The fuzzy comprehensive evaluation method is adopted as the evaluation method for the sustainability of urban space development. Firstly, the AHP method is applied to determine the weights of each specific indicator in the index layer. The sustainability of the current status of underground space development reflected by each indicator is determined by the expert scoring method. Finally, the evaluation results of "sustainable urban spatial development"were obtained using the spatial sustainability model for the example of the cities. In summary, the sustainable urban spatial development model based on smart cities can reflect the development status, development trend, and coordination with the comprehensive external environment of urban space in a comprehensive manner, and can measure and evaluate the degree of sustainable development, thus helping to identify problems that limit sustainable development. © 2023 Xiaolei Ma, published by Sciendo.
