### Reasons for Changes in Green Visibility Equity
Prioritizing ground-level roads with adequate greenery could address these issues. In terms of overall equity, Gini coefficients vary significantly across different districts, likely due to differences in geographical location and resource allocation. The JA District had the lowest Gini coefficient and broke the pattern of inequality in 2017. Located on the northern bank of the Yangtze River, it is home to Hankou Riverside Park, the largest riverside green plaza in Asia. During the 13 th Five-Year Plan period, driven by preparations for the Military World Games, the district saw a significant increase in green space, with a 5.28% rise in green coverage [61]. In contrast, the HS District, with its concentration of universities and rich educational resources, has seen an increase in population density, putting pressure on urban green spaces and public open areas [62]. This has made it the only district with a substantial disparity in resource distribution. To alleviate these pressures, reducing hardscape in walkways, plazas, and roads is essential to provide more space for tree roots and enable trees to develop full canopies, improving green coverage and environmental quality in high-density areas. In terms of local equity, the spatial distribution of the LQ is influenced by both population density and visibility levels, consistent with [PERSON]'s findings [PERSON] et al., 2024 [33]. Even in residential clusters with many high-visibility streets, the location entropy value may be diluted by a larger population. Our study identifies a certain mismatch between the spatial growth of green spaces and population density, a pattern also observed in many other Chinese cities [63]. Previous researchers would attribute green inequities to the planning system and the market economy [64,65]. Here, we argue that similar market drivers may further exacerbate residential spatial differentiation in Wuhan, ultimately leading to visibility inequality. Although most urban green space in China is provided by the government, it is maintained through local public funding, which is closely tied to the economic conditions of the community [37]. Consequently, economically advantaged communities tend to have more street greenery due to their ability to cover maintenance costs, while lower-income areas with fewer green resources often lack adequate maintenance [33,38]. For instance, in the Jianghan SecondBridge Subdistrict of the HY District, early welfare housing allocated by work units has attracted migrant workers with low rental costs but suffers from poor green services and inadequate provision. To address this disparity, government-led maintenance should replace local community-based systems, ensuring equal access to quality greenery regardless of a community's economic conditions. Additionally, green gentrification has emerged in low-income communities where greening measures were implemented [66]. For instance, the Yangtze River waterfront area launched the New Port Yangtze City project in 2013. Residential types transitioned from traditional villages and neighborhoods to integrated residential, commercial, and office spaces, enhancing green space services. However, this transformation led to a surge in housing prices, forcing many low-income residents affected by demolition to relocate to the urban periphery, further limiting their access to green space benefits [67]. To address this, urban planning should ensure equal green space allocation in both high- and low-income neighborhoods to prevent green gentrification. Additionally, reducing hardscape in dense areas, such as walkways and plazas, can create more opportunities for greenery without triggering surges in house prices.
