ABSTRACT Ecological networks (ENs) are vital for maintaining regional ecological security and preserving biodiversity. While various methods exist constructing ENs, their effectiveness across different spatial scales, particularly in urban agglomerations, has not been thoroughly investigated. This study focuses on the Yangtze River Delta agglomeration (YRDUA), ENs at three scales: agglomeration, metropolitan area, city. Two were employed each step, outcomes evaluated ranked using specific indicators. The results indicate: (1) For source identification, distribution of sources identified by is consistent same scale, with number scales being around 600, 140, 160, respectively. (2) resistance surface construction, although there differences between two methods, final value shows relatively small changes. (3) Regarding corridors, quantities 1470, 380, 410, indicators, α values 0.71, 0.85, 0.81, respectively; β 2.42, 2.68, 2.61, γ 0.90, 0.88, Cr 0.80, 0.68, Comparing ranking all indicators can yield: MSPA method, surfaces constructed Spatial Principal Component Analysis (SPCA), corridors extracted Linkage Mapper yielded optimal results. At city Analytical Hierarchy Process (AHP), Graphab These findings provide methodological guidance offer new insights landscape planning multiple levels.

The Southwest Alpine Canyon Area (SACA) is a typical ecologically sensitive location in China; therefore, constructing and optimizing an ecological network for this area essential to ensure the regional security of its fragile ecosystems. This study employed InVEST model quantitatively assess habitat quality SACA years 2000, 2010, 2020. sources were determined based on results assessment Morphological Spatial Pattern Analysis (MSPA). Finally, corridors, pinch points, barrier points identified using circuit theory. indicated that SACA’s was relatively good, but experienced slight degradation from 0.87 2000 0.84 Anthropogenic activities have been as primary contributor decline region. Geographically, significantly poorer southeast northwest SACA. A total 319 identified, predominantly located southwest northeast SACA, comprising 43.27% area. Furthermore, 94 corridors delineated, covering 74,015.61 km2 extending over 182.80 km length total. 38 39 distinguished, with noticeable concentration regions undergoing degradation. Overall, while structure complex highly interconnected, it faces challenges relating material cycling circulation.

Existing methods for constructing Landscape Ecological Networks (LEN) either focus on functional attributes or structural and also do not address the dynamic impact of urban development ecological spaces. To these limitations, this paper proposed evaluating maximum connectivity (k) potential LEN, composed existing spaces, using a network fault tolerance index. We then used graph-based networking technology to construct optimal LEN structure based Specifically speaking, first, we identified with highest ecosystem service capacity lowest cost in study area. Using four landscape pattern metrics, comprehensively evaluated index as k determined that = 7. modeled weighted graph transformed optimization problem into k-edge addition problem. This calculation yielded seven schemes, each corresponding different priority orders new corridors value. captures changes space patterns offers diverse solutions. It provides practitioners flexible spatial strategies impacts urbanization.

Abstract Shenzhen, a bustling metropolis in China, is currently grappling with the delicate balance between urban expansion and environmental preservation. This study finds that disintegration of habitats due to development Shenzhen city significantly impacts ecosystem animals plants, detrimentally altering their living conditions. The results reveal construction land China has surged by an impressive 84.39% 2000 2020, which come at cost diminishing wetlands, farmland, woodlands 57.24%, 16.58%, 1.86%, respectively. Between 1980–2020, expanse expanded dramatically, growing from 16.0 square kilometres 850.2 kilometres. transformation was primarily driven rapid conversion forested areas, saw staggering decrease approximately 300% 780 km 2 2020. Additionally, half Shenzhen’s can be attributed agricultural land, additional 40% stemming clearing forests 9% resulting water resources. Furthermore, non-urban green spaces, particularly built-up have expanded, now encompassing 60% 2018. Therefore, based on existing literature authoritative legal texts, this aims examine frameworks government and, along China’s national legislation, make room for wildlife biodiversity conservation like Shenzhen.

The pivotal aspects of enhancing regional ecosystem services and augmenting socioeconomic growth lie in optimizing the land-space development protection strategies, coupled with establishment a robust ecological network (EN). This article examines Poyang Lake area employs MOP model, NSGA-II, PLUS model to determine best sustainable land use strategy. Subsequently, MSPA, InVEST circuit theory, complex network, others are employed construct analyze EN across three time periods. Ultimately, is optimized based on spatial priority, obstacle areas, nodes. results show following: (1) From 2005 2035, more construction will be developed around Greater Nanchang other urban centers. In BAU scenario, expand faster, while cultivated land, forest, grassland, bare continue decline. SD alteration comparable minimal, rate slow, all decline little, water increase slightly; (2) While sources decreased corridors become longer narrower distribution ENs different periods small, quantitative structure essentially unchanged scenario; (3) Based topological ENs, it found that clustering nodes scenario obvious, importance enhanced, efficiency information transmission improved, radiation range wider stable; (4) greatest priority each period concentrated Lake. improves, 7025 km2 restoration identified, 41, 31, 36 breakpoints first, second, third levels. study’s findings can assist shape theoretical practical approaches governance great lake areas.
