Accelerated urbanization and the excessive exploitation of tourism industry are leading to a diminution ecological spaces in tourist cities. Ecological networks an effective method for improving patch connectivity maximizing space. However, previous research on predominantly focuses static snapshots, ignoring fact that landscape entities with considerable spatiotemporal structural dynamics changes. To fill this gap, we first constructed Guilin 1990, 2000, 2010, 2020, employing integrated valuation ecosystem services tradeoffs (InVEST) model, morphological spatial pattern analysis (MSPA) method, circuit theory. Subsequently, analyzed evolution proposed strategies territorial space management.

Climate change and human activities are seriously affecting the ecological level economic development of county-level cities. Mianzhu City is a typical city located within Chengdu-Chongqing Economic Circle Yangtze River Belt. The study selected primary sources by analyzing high-level ecosystem service functions over time, using Morphological Spatial Pattern Analysis (MSPA). Ecological resistance surfaces were constructed natural factors to address risks associated with future urbanization. construction security pattern (ESP) followed source–corridor–node paradigm, incorporating changes in risks. From 2010 2020, values declined overall, significant spatial variations. Human increased ecologically fragile areas, aggravating exposure from climate urban expansion. protection restoration zones identified, nature reserves north southern center as core. In 19 46 corridors distribution “more length short north, less long south”. Additionally, 41 pinch points 16 barrier determined. Considering core areas services lands human-intensive activities, setting up general idea centered on forests, river corridors, artificial landscapes. provides new insights into constructing optimizing ESP, offering crucial references for rapid urbanization planning regions.

Abstract The scientific establishment of the Ecological Security Pattern (ESP) is crucial for fostering synergistic development ecological and recreational functions, thereby enhancing urban protection, development, sustainable growth. This study aimed to propose a novel method constructing ESP considering both reconstruct by weighing relationship between protection development. Utilizing Fuzhou City as case study, comprehensive application methodologies including Morphological Spatial Analysis (MSPA), landscape connectivity analysis, ArcGIS spatial social network analysis (SNA), circuit theory employed develop Recreational (RSP). A trade-off matrix created facilitate reconstruction ESP, delineate functional zones, identify strategic points, followed thorough optimization strategy. revealed 36 source areas (ESAs) within City, encompassing total area 5807.90 km², predominantly situated in western northern regions. Additionally, 98 corridors (ECs) were identified, extending over 2500.55 km, alongside 100 pinch points (EPPs) 146 barrier (EBPs). city also contains 57 nodes (RNs),, which display distribution characterized “dense east, sparse west” pattern. Furthermore, 165 (RCs) extracted, covering distance 3795.21 km. Based on matrix, was categorized into eight zones: core zone, important eco-recreation key secondary elastic zone.The identified 95 475 sub-strategic. multifunctional complex constructed, “one core, five districts, six corridors, seven wedges”, tailored planning strategy proposed. research contributes theoretical framework construction supports coordinated high-quality activities environments.

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.
