As modern society increasingly emphasizes quality of life, historic districts face the challenge of balancing the preservation of traditional culture with the integration of urban development. Many historic districts today struggle with low vitality and limited visitor engagement. By adopting sustainable development strategies, such as promoting tourism, these districts have the potential to enhance economic vitality. This study explores the spatial morphological characteristics of the ShuiXiLin Historic District (SHD) in Fuzhou, using spatial syntax theory and tools within the framework of sustainable urban renewal. The study proposes three strategies for the district: (1) enhancing connectivity positively influences the public experience within the SHD; (2) strengthening the district’s primary axis amplifies its influence across the area; (3) implementing protective reuse of historical buildings and improving service facilities can significantly enhance the district’s vitality. Through theoretical analysis and a review of existing research, this study proposes revitalization strategies aimed at formulating sustainable development plans for the district. These recommendations are intended to offer valuable insights for urban renewal projects and provide theoretical support for planning decisions related to the vitality of historic districts. This research illustrates the effective use of spatial syntax in historic districts, offering a robust method to evaluate and enhance the spatial structure and vitality of heritage areas. It supports sustainable development by integrating preservation with modern needs, ensuring a balance between conservation and urban growth.

The effect of urban green spaces on traffic noise reduction has been extensively studied at the level of single vegetation, hedges, etc., but there is a lack of corresponding studies at the scale of spatial patterns of urban green spaces. Therefore, this study aims to analyze the relationship between the spatial pattern of urban green space and the change in green space’s noise reduction capacity. Through the morphology spatial pattern analysis method, this analysis divides the urban green space in the Fuzhou high-tech zone into seven types of elements with different ecological definitions and simulates the noise condition of the urban environment with the presence of green space as well as without the presence of green space by computer simulation, calculates the distribution map of the noise reduction produced by the urban green space, and analyzes the correlation between the seven types of green space elements and the noise reduction with the geographically weighted regression modeling analysis. The study finds that (1) Urban green space patterns can significantly affect the net noise reduction of green space. Areas with high green coverage can produce a stronger green space noise reduction effect. (2) More complex green space shapes and more fragmented urban green space can produce higher noise reduction. (3) The green space close to the source of noise can exert a stronger noise reduction effect. Therefore, in the process of planning and design, from the perspective of improving the urban acoustic environment, the configuration of high-quality green spaces in areas with higher levels of noise pollution should be given priority, which may have better noise reduction effects.

With the increasing frequency of extreme disasters, effectively utilizing park green spaces in both daily life and disaster scenarios has emerged as a new challenge, particularly in county-level cities. In this context, the core planning area of Anxi County in Quanzhou was selected as the study site. By adjusting the layout and scale of park green spaces, this research investigates how such modifications influence the quality of the urban wind environment and green space accessibility in county-level cities. The results show the following: (1) Under the vegetation ratio of trees–shrubs–herbaceous plants, the ventilation performance of the urban wind environment improved at a daily wind speed of 5 m/s. The wind speed increased from the current low base speed (0–1 m/s) to a moderate speed (2–5 m/s), significantly enhancing the comfort of the population. (2) Under the vegetation ratio of trees–shrubs–herbaceous plants, the overall disaster-prevention performance of the county improved. During typhoon wind speeds (50 m/s), the wind speed gradually decreased from partially higher speeds (40–50 m/s) to lower speeds (10–20 m/s), resulting in a significant improvement in the wind environment. (3) After optimizing the layout of park green spaces, accessibility was greatly enhanced, better meeting the needs of the population in the developed area.

The discrepancy between the physical accessibility and perceived accessibility of public service facilities in coastal towns and villages of Fujian, China, was investigated in this study. Through a spatial distribution analysis of education and medical service facilities in Liushui Town and Xingchen Town, the equity and coverage levels of various facilities were evaluated based on the residents’ physical travel costs and perceptions. The results show pronounced spatial heterogeneity between the physical and perceived accessibility across different regions. Our findings suggest that, while certain areas boast a lot of physical access to facilities, the residents’ perceived access is significantly influenced by factors such as the terrain, transportation conditions, and the types of available travel tools. The findings of this study provide a scientific basis for optimizing the allocation of rural public service facilities, aiming to bridge the foundational service gap between urban and rural areas and promote the equitable development of rural living environments.
