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.

The construction of an ecological security pattern (ESP) is important undertaking in ensuring the stability ecosystem and long-term growth humanity. Existing research, However, existing research often overlooks quantification policy implications ESP development. objective this paper was to bridge gap by integrating analysis (PQA) with nature, society into providing targeted management recommendations. texts were quantified reusable data, which served as a foundation for selection indicators optimization patterns, using machine learning techniques. methodology "Patch-matrix-corridor" used create spatially correlated pattern. Through factor Random Forest (RF), impact each indicator on thoroughly examined, offering substantial support development planning. Guangdong-Hong Kong-Macao Greater Bay Area(GBA) selected study area, found that: (1) proposed framework PQA based-ESP could provide useful eco-management tools. (2) Policy adaptability had environmental GBA, but service index has highest impact. (3) Applying framework, we identified total 1,993 km2 sources, 23 key corridors, 58 general 31 nodes. An improved ESP, characterized "one circle, two bays, three rivers, multiple areas, nodes," constructed GBA. (4) Given multi-scale analysis, tailored recommendations city study's findings offer actionable solutions international community facing growing challenges.

The global ecological decline resulting from urban development presents a significant challenge for numerous regions striving to reconcile conservation efforts with developmental needs. This study explores the relationship between ecosystem service value (ESV) and habitat quality (HQ) under various scenarios elucidate prospective trajectories. utilized PLUS model simulate land use patterns in Chengdu metropolitan area across four distinct scenarios. Furthermore, it employed equivalent factor method Invest quantify ESV HQ values, investigated coupling coordination each city using (CCM). findings are as follows: (1) Between 2000 2020, primarily expanded through of construction land. (2) Concurrently, demonstrated fluctuating trend characterized by an initial succeeded upsurge, culminating Development–Ecological Balance Scenario. Likewise, displayed similar pattern increase, reaching its zenith Ecological Dominance (3) exhibited variability cities Ultimately, this offers distinctive perspective on evaluating interplay conservation, providing valuable insights promoting sustainable other regions.

Studying the spatiotemporal trends and influencing factors of vegetation coverage is essential for assessing ecological quality monitoring regional ecosystem dynamics. The existing research on variations their driving predominantly focused inland ecologically vulnerable regions, while coastal areas received relatively little attention. However, with unique geographical, ecological, anthropogenic activity characteristics, may exhibit distinct distribution patterns mechanisms. To address this gap, we selected Shandong Province (SDP), a representative province in China significant natural socioeconomic heterogeneity, as our study area. investigate coastal–inland differentiation dynamics its underlying mechanisms, SDP was stratified into four geographic sub-regions: coastal, eastern, central, western. Fractional cover (FVC) derived from MOD13A3 v061 NDVI data served key indicator, integrated multi-source datasets (2000–2023) encompassing climatic, topographic, variables. We analyzed characteristics dominant across these sub-regions. results indicated that (1) FVC displayed complex notable gradient where decreased towards coast. (2) influence various significantly varied sub-regions, dominating an east–west polarity, i.e., explanatory power intensified westward resurging zones. (3) intricate interaction multiple influenced spatial FVC, particularly dual-factor synergies interactions between other were crucial determining coverage. Notably, zone exhibited high sensitivity to drivers, highlighting exceptional ecosystems human activities. This provides insights different geographical zones well factors. These findings can help understand challenges faced protecting vegetation, facilitating deeper insight responses enabling formulation effective tailored strategies promote sustainable development areas.

Protecting ecological sources and restoring stepping stones (ESSs) are key to constructing security patterns (ESPs) in small-scale rural areas. Ecosystem services (ESs) associated with Water–Energy–Food (W-E-F) influence the of However, how construct ESPs enhance synergy connectivity W-E-F systems remains unclear. This study thus proposes a framework ESP construction optimization based on coupling coordination analysis ESs related W-E-F, including Water yield, Carbon storage, Food production. Using Changsha–Zhuzhou–Xiangtan Green Heart region as case, it identifies corridors through degree (CCD) model circuit theory. Moreover, optimizes by incorporating optimal ESS plan improve source connectivity. The results show 14 patches covering total area 86.73 km2 117.21 km corridors. Three plans evaluated, Option II proving optimal, increasing corridor length 31.02% 57.10%, which is high CCD three ESs. “One Core, Zones, Four Corridors, Multiple Points” scheme was defined ESP. underscores significance restoration advocates shift from “single ES” “coupled ESs” perspective.
