Twenty-six cities in the Yangtze River Delta urban agglomeration were taken as research object, and this study comprehensively evaluated urbanization quality ecological resilience from 2005 to 2020. On basis, spatiotemporal evolution characteristics main influencing factors of coupling relationship between systematically explored using a coordination model panel Tobit regression model. The results can be summarized follows: (1) 2020, continued grow, level grew slowly fluctuated, development among municipalities tended balanced. (2) overall degree showed continuous increasing trend, type changed basic good coordination. number with lagging decreased significantly; spatially, gap narrowed, gradually clustered. (3) that differences spatial mainly resulted interaction drivers such real utilized foreign capital, per capita GDP, carbon emission intensity, proportion science technology expenditure fiscal expenditure, ratio disposable income rural residents, fixed asset investment municipal utility construction, index land area ratio. In future, should improved based on according local conditions, seven carefully examined accelerate high-quality integrated Delta.

Scientific planning of landscape ecological networks can promote the overall improvement urban ecosystems, but current basis on single index and simple network extraction is not enough to support sustainable development. Comprehensively understanding mechanism ecosystem operation, this study firstly constructed an health (LEH) assessment model integrating pattern, process, function. Taking Harbin central city as area, conducting a LEH practical provide scientific for its planning. Secondly, principal component analysis (PCA), minimum cumulative resistance (MCR) model, hydrological were applied extract network. Finally, introducing complex theory optimize determine key nodes. The results indicated that (1) decreased from 0.481 0.446 2011 2020, with significant spatial differentiation. (2) 50 source landscapes 8 sink identified, fewer corridors, source-type nodes 28 weak-type selected. (3) Based LDF strategy theory, there 14 additional connectivity resilience greatly enhanced, eight identified. (4) plan presented pattern consisting "three rings, four pieces, cores, multiple corridors", which maintain development ecosystem. In addition, aims propose more efficient framework new ideas construction areas, are most profoundly urbanized in world.

In the context of accelerating ecological fragmentation, it is urgent to enhance interconnectivity urban patches form a resilient network (EN). The construction Natural Protected Area (NPA) system proposed in 2019 latest strategy implemented by China protecting spaces. However, effectiveness this has not been adequately demonstrated. This study specifically analyzes concrete impacts natural protected area on resilience networks (ENs). economically developed Urban Agglomeration around Hangzhou Bay (UAHB) was chosen as an example for argumentation. Firstly, we utilized circuit theory construct EN consisting 173 sources and 401 corridors. Secondly, were categorized into three levels based their connectivity values. Finally, dynamic disturbance scenario simulation framework constructed evaluate impact NPA EN. results indicated that: (1) preceding 47% are crucial maintaining EN; (2) Compared with other spaces, NPAs have 38% 1100% greater effect first second-level sources, respectively, while its third-level 118% lower. innovatively investigates differential hierarchical areas unprotected environment.

Rural areas in ecologically fragile regions face obstacles of underdeveloped social economies and poor natural conditions. Existing studies on the optimization rural settlements have mainly focused regional ecological protection paid inadequate attention to social-economic dimensions their interaction with dimensions. We propose an analytical framework for spatial from a social-ecological perspective. Using Kaitong Town, located western Jilin Province, China, as case study, we analysed development capacity different villages evaluated ecosystem resilience. Based combinations resilience, divided study area into four zones: relocation merger; aggregation promotion; key development; stabilization improvement. within merger zone were identified requiring resettlement. Two directions are suggested: one adjacent village other promotion same administrative village. The proposed provides scientific basis optimizing layout can play important role realizing sustainable areas.

With the emphasis of modern societal development on ecological environment, urban environmental issues have been lessened. However, green space occupies a significant amount land resources, leading to more prominent human-land conflicts in some areas, thus creating serious social that urgently require solutions. As result, and factors must be integrated into sustainability planning. Using Chinese city Fuzhou as an example, this study constructed adaptive cycle model framework for sustainable based theory by coordinating three core characteristic attributes development: potential (urban potential), connectedness (conflicting use), resilience (suitability development). This was used identify stages (exploitation, conservation, release, reorganization) different areas city. Finally, value landscape created verified through multi-scenario simulation. The results were follows: 1) expansion under constraints had higher could effectively mitigate use while balancing socio-ecological contradictions during development; 2) effects varied across 3) our proposed planning pathway divided eight categories targeted measures zoning characteristics. can alleviate contradiction between development. It policy tool managing assessment future use.

The conflict between socio-economic development and ecological environmental protection presents a significant challenge to achieving regional urban sustainable development. In Zhaotong City, Yunnan Province, China, this arises from the interplay expansion land, creating fundamental tension built-up non-built-up ecosystems. This study focuses on investigating spatial characteristics of expansion, constructing an security pattern based ecosystem service functions sensitivity, utilizing integrated models simulate paths analyze their formation mechanisms. results highlight that City has undergone rapid characterized by linear growth surrounding central city, specifically in east, north, west directions. areas exhibits discontinuous dotted-star distribution, with concentrated urbanization distinct boundary observed Zhaoyang District. contrast, other experience scattered indicative random land encroachment. Through simulation, three primary axes are identified: western town sprawl belt, axis, resource-rich corridor. Ecological conflicts primarily arise District, Zhenxiong County, Yanjin County. By combining these findings, analyzes scenario evolution revealing transition spreading spillover single center (Zhaoyang Ludian) during circle phase polycentric centered around District along axial radial paths. conclusion, contributes our understanding challenges posed City. findings underscore importance integrating considerations into planning processes need for practices achieve harmonious coexistence security. insights gained research offer guidance fostering beyond.

ABSTRACT Anthropogenic interference causes ecological fragmentation and vulnerability, weakening urban ecosystems' adaptive capacity. The network is based on the principles of landscape ecology, connecting resource patches through linear corridors to protect biodiversity integrity, enhance environmental carrying capacity, improve ecosystem resilience. However, current research resilience often relies single methods scales, overlooking potential discrepancies between different approaches scales. This study uses Zhejiang construct networks with structural, functional, integrated at provincial, agglomeration, city levels. performance these in protecting structure, maintaining function, ensuring overall was compared, yielding following results: First, spatial output consistency source areas across scales for three ranged from 50.48% 97.81%. Second, approach not optimal all goals. structure‐oriented method demonstrated cross‐scale applicability structural goal, while function‐oriented strategy performed well functional Third, scale analysis showed results provincial agglomeration levels when meeting same objectives, but level. By expanding methodologies perspectives field resilience, this assesses It found that do always effectively coordinate multiple protection objectives; thus, large‐scale strategies cannot be directly applied smaller practical applications. proposes validates a multi‐scale, multi‐method framework assessing networks. reveals differences methods, providing valuable theoretical insights guidance future particularly regarding
