## 4 Conclusions  
1. We created a thorough evaluation mechanism for the viability of project construction in Xiongan New Area. Eight second-level evaluation indices of foundation bearing capacity at different depths, soil compressibility, groundwater depth, water and soil corrosivity, and land stability are screened out after the engineering geological \begin{table}

A thorough assessment of the appropriateness of engineering construction in Xiongan New Area was carried out. The suitability assessment grade standard was developed using a cloud model to assess the appropriateness of Xiongan New Area, and the index weight was determined using the analytical hierarchy process and the entropy weight technique. This study's findings indicate that Xiongan New Area's engineering construction conditions are generally good, that the suitable and more suitable areas make up more than 80% of the new area's total area, and that both the generally suitable area and the poorly suitable area have significant environmental geological problems like land subsidence, sand liquefaction, and flood inundation. 3. Comparisons were made between the outcomes of the cloud model's evaluation and those of the conventional suitability evaluation model. Despite some discrepancies between the two, the general conclusions are the same, proving the viability and efficacy of the cloud model in the evaluation of engineering construction's appropriateness. 4. The conceptual model of the evaluation index system must be established before the evaluation method based on cloud theory can be implemented. Through the cloud generator, this method realizes the organic combination of uncertainty and ambiguity among the multi-factor indicators of the suitability evaluation of urban engineering construction in comparison to the conventional assessment technique. The assessment index system is a crucial element in engineering practice that influences site selection for engineering projects as well as disaster prevention and mitigation. The choice of assessment indices in this work is mostly based on the most recent technical requirements of engineering and geological exploration. The consideration is not thorough enough, and the actual problems outside the framework are less complicated. It must be reinforced in a follow-up study to increase the research findings' maturity and applicability. 5. This research was conducted for the Xiongan New Area's general planning, and as such, its evaluation accuracy does not satisfy the standards of regulatory detailed planning.
