Introduction In the context of escalating public health crises in megacities, promoting green and healthy urban spatial development is crucial. It not only contributes to economic growth environmental sustainability but also significantly impacts residents. Methods This study utilized land use data from 2000 2021 Chongqing, China, investigate characteristics patterns change space distribution. Spatial analysis methods were employed, an econometric model was constructed analyze mechanisms these changes, considering factors such as drivers, governmental regulation, social dynamics. Results The results reveal that spaces Chongqing metropolitan area are primarily concentrated inner suburbs with limited distribution central areas, exhibiting a distinct gradient. overall size has been decreasing, particularly suburbs. primary this reduction include edge erosion suburbs, inward contraction minor perforation new towns. Discussion indicates industrial growth, dominant contributing spaces. impact dynamics, demand, appears be relatively insignificant. Conversely, government planning policies investments play crucial role protection These findings emphasize need for effective strategies prioritize conservation expansion enhance megacities.

The establishment of ecological security patterns (ESPs) has emerged as a significant approach to address the inherent conflict between preservation and economic advancement. Existing studies commonly only focus on supply ecosystem services (ESs) but pay little attention demand for ESs less service flow (ESF), which leads limited satisfaction space planning with needs human society. This study takes West Liao River basin an example design comprehensive pattern construction optimization method. quantified soil conservation (SC), carbon fixation (CF), water purification (WP), windbreak sand (WS) provision (FW) five key in area from 2000 2020, discussed strategy ESPs perspective “supply-flow-demand”. results indicated that total 25 source areas have been identified, optimized 3.57×104km2, 53 corridors, including 15 primary 38 secondary 31 checkpoints, 16 obstacle points. Based spatial distribution sources, “four zones, three belts, multiple branches” constructed. sources watershed is mainly forest grassland northern, central, eastern, southwestern regions, pinch points predominantly observed central western first-class corridors are located region. Research shown there mismatch within area. use “supply-flow-demand” framework can more accurately identify traditional methods not able identify. research finding will contribute enhancing comprehension ecosystems basin. aims explore optimize ESPs, certain universality reference value, provide new paths decision support future regional patterns.

Ecological Security Patterns (ESPs) are important nature-based solutions for ecological problems caused by urbanization and industrialization. Previous studies on ESPs focus natural conditions only, yet do not incorporate the need social equity. This study aims to address this quandary area of Wuhan identifying extracting sources corridors, followed an sensitivity assessment, minimum cumulative resistance model buffer analysis, in order construct optimize security patterns. The optimization construction most suitable patterns relies equity aspects, including quality urban services improvement well-being residents. results demonstrate: (1) There 19 51 corridors with a total length 840.10 km. (2) To cater needs, it was necessary add one additional amendment source, 14.89 km2, 25 new 287.8 (3) Optimizing is possible through derivation restoration area, control shield area. indicate feasibility simultaneously protecting realizing

During the COVID-19 pandemic, people have seen precious value of park green space for health. In post-COVID-19 Era, it is essential to understand different needs and expectations communities use space. A myriad previous studies focused on whole city’s demand space, while few examined spatial equity from a supply-demand perspective. This paper aims investigate differences in accessibility among ages at community scale. Specifically, better evaluate account travel choice, we compared effects two-step floating catchment area (2SFCA) method containing distance decay functions (i.e., improved 2SFCA methods) by considering traffic network scale addition, methods with traditional 2SFCA. study investigated 1184 total population 6,468,612 central urban districts Wuhan. The results showed that high accessible were concentrated center along Yangtze River. outperformed 2SFCA, presented smoother gradient information. It was revealed over half communities’ levels did not match their density. Inequality found ages, especially youth (Gini coefficient as 0.83). difference age structures implies need integrate planning into Era.
