## 1 Introduction  
Urban environmental geological issues have gradually garnered attention as China's urbanization process has accelerated in recent years. Urban development is reliant on the geological environment, which has a direct impact on city planning and development. At the same time, urban development responds to the geological environment. Numerous engineering, geological, and environmental issues with urban development include surface deformation, groundwater contamination, the instability of the rock surrounding subsurface caves, harm to neighboring structures, and the degradation of the ecological environment. Therefore, it is crucial to use the geological environment in urban design and construction in a scientifically sound manner in order to change it and make it compatible with the geological environment [1]. The development and construction of Xiongan New Area as a new ecological metropolis will inevitably face constraints from engineering geology and environmental geology. The suitability study of urban construction can mitigate or even prevent various geological problems caused by engineering construction. It can also facilitate and maintain the coordination between the urban environment and development to the greatest extent possible, based on a comprehensive understanding of the engineering geology and environmental geological conditions in the new area [2, 3, 4, 5, 6, 7]. Although there is currently no scientifically unified understanding of the application of engineering construction suitability evaluation methods among academics at home and abroad, the mathematical models and analytical theories of various widely used methods can be roughly categorized into five main categories. Through the use of the spatial data superposition analysis method in geographic information systems (GIS), the artificial neural network method, and the analytic hierarchy process, [PERSON] [8] developed an assessment system to evaluate the suitability of engineering construction in Minneapolis, Minnesota based on topography, engineering geological circumstances, hydrogeological conditions, and other indicators. He then utilized a complete index model for evaluation purposes. Professor [PERSON] [9; 10] devised a geological disaster risk assessment system for the Glenwood Springs area on a GIS platform. The system evaluated the region's geological disaster risk and provided a framework for regional urban planning and construction. Based on the fuzzy comprehensive assessment approach, [PERSON] and coworkers [11] conducted a zoning evaluation study on the acceptability of site engineering construction of various building kinds in a plain area. A waste treatment plant in Israel's Kurdistan Province is used by [PERSON] [12] as the research object. He employs the analytic hierarchy approach to systematically analyze and assess the site suitability of the plant. German academic [PERSON] and others [13] included elements like topography, geological conditions, and environmental geological issues into their analytic hierarchy approach to thoroughly assess the viability of future urban development regions. [PERSON] et al. [14] conducted a systematic and comprehensive evaluation of the suitability of the composite foundation of construction land in their study area through in-depth analysis and research on the engineering geological conditions of the construction land in a certain city. With the aid of the MapGIS spatial analysis function and the unit multi-factor grading weighted index method, [PERSON] [15] and others investigated the suitability of urban construction land in the Yellow River alluvial plain. They used the geological environment and other elements to evaluate the suitability of construction land development in the plain area. Due to differences in their mathematical models and analytical logic, each of these traditional methods has its own advantages and limitations (Table 1). However, the factors affecting the suitability of engineering construction are often complex, fuzzy, and random.
