With the acceleration of urbanization, accessibility and equity urban green spaces have become crucial issues in planning public health. In context 15-min living circle, whether residents can conveniently reach parks within a walkable or bikeable time frame directly impacts their quality life social well-being. Traditional park evaluation methods, such as G2SFCA, effectively measure but fail to fully account for diversity travel modes impact regional disparities on equity. This study employs TB-G2SFCA method, integrating concept analyze Dianchi Lake ring area Kunming under different modes. The findings reveal significant walking cycling, particularly suburban communities distant from city center, where many areas cannot 15 min. Although improves driving transit modes, resources remain concentrated well-connected areas, leaving peripheral regions with insufficient access. Compared traditional G2SFCA approach more accurately reflects spatial differences across suggests that future should optimize resource allocation, improve transportation networks, enhance areas—especially cycling—to achieve equitable sustainable distribution spaces.

Improving carbon sink capacity is critical for meeting energy conservation and emission reduction targets, along with low-carbon development goals. Although many researchers have recognized that urban space can significantly influence the of sinks in areas, few studies quantified impact landscape patterns, particularly green (UGS) morphology, on sinks. This study quantitatively investigated UGS morphology using panel data from nine cities Guangdong–Hong Kong–Macao Greater Bay Area (GBA), China, 2000 to 2017. A series metrics land-use was first selected quantify four dimensions UGS: scale, compactness, type diversity, shape complexity. Subsequently, estimated a model. The main findings were as follows. (1) From results, GBA found be an evolutionarily stable state, reflecting relatively limited potential enhancement region. (2) AREA_MD mainly distributed between 0.18 0.27.
