## 5 Conclusions  
This paper focuses on the wind resilience of Yazhou arcade districts in Sanya, analyzing the influencing factors from four key aspects: block level, building level, typhoon characteristics, and emergency management. A system analysis model for the influencing factors of wind resilience in China's coastal historical districts is constructed. The key findings of this paper are as follows. 1. The causal factors that rank high in centrality are primarily causal factors, with most falling under the categories of building level and typhoon characteristics. The centrality of windproof design (\(S_{6}\)) ranks first, indicating that this factor occupies a core position at the building level and exerts significant influence on the entire system. Therefore, the internal structure of the building should be periodically inspected and reinforced on a daily basis, and building materials with wind-resistant properties should be used when reinforcing and repairing the exterior of the building. The centrality of hazard investigation (\(S_{11}\)) ranks second, belonging to the emergency management level, which highlights its significant influence on the wind resilience influencing factor system of China's coastal historical districts. Therefore, it is particularly important to establish a special patrol system for hidden dangers in historical districts. The centrality rankings of typhoon direction (\(S_{8}\)) and architectural composition (\(S_{4}\)) are third and fourth, respectively, indicating that both factors are significant influencers of the wind resilience in China's coastal historical districts, with typhoon direction (\(S_{8}\)) belonging to typhoon characteristics and architectural composition (\(S_{4}\)) to the building level. The causal factors primarily include typhoon level (\(S_{7}\)), emergency plan (\(S_{10}\)), block direction (\(S_{3}\)), architectural composition (\(S_{4}\)), block form (\(S_{2}\)), block density (\(S_{1}\)), typhoon wind speed (\(S_{9}\)), and safety education (\(S_{12}\)). Among these, block direction (\(S_{3}\)), block form (\(S_{2}\)), and block density (\(S_{1}\)) fall under the block level, indicating that the block level significantly influences the wind resilience influencing factor system of China's coastal historical districts. Therefore, wind tunnel experiments can be conducted for simulation at the block level, and the density and layout of the block can be optimized based on the simulation results to improve the wind resistance of the district. 2. The 12 influencing factors affecting the wind resilience of China's coastal historical districts are categorized into five distinct layers. The lower-level influencing factors are typically independent factors, the middle-level factors are mainly spontaneous and linkage factors, while the upper-level factors are generally dependent factors. The influencing factors in the fifth layer are block form (\(S_{2}\)), typhoon level (\(S_{7}\)), and emergency plan (\(S_{10}\)). The three factors in the fifth layer exhibit greater driving force and are the most fundamental and important influencing factors in the system. The influencing factors in the fourth layer include architectural composition (\(S_{4}\)), typhoon wind speed (\(S_{9}\)), and safety education (\(S_{12}\)). The driving force of the factors in the fourth layer is slightly greater than their dependence, indicating their strong connecting role. The influencing factors in the third layer are block direction (\(S_{3}\)) and hazard investigation (\(S_{11}\)). The driving force of the factors in the third layer is slightly greater than their dependence, positioning them in the middle of the multi-layer hierarchical structure model. This allows them to effectively connect the relationships between the lower and upper influencing factors. The influencing factors in the second layer are block density (\(S_{1}\)), building structure (\(S_{5}\)), and typhoon direction (\(S_{8}\)).
