The ecological security of karst basins is receiving increased attention as a result intense human activity and climate change. However, how evolves in spacetime the optimization patterns still remain unclear. This study developed methodological framework for evaluating optimizing Lijiang River Basin (LRB). 3S technology was used to analyze current status evolution characteristics landscape LRB from 1990 2020. identified optimized by adhering basic paradigm “source identification–resistance surface construction–corridor extraction–node determination”. results showed that overall at medium high level, with an index showing initial increase followed decrease. exhibited 24 pinch points, 74 corridors, 30 sources, 6 barrier points. predominant types found within these points encompass forests, cultivated land, urban areas. A scheme “three cores, two belts, six zones” proposed optimize pattern LRB. provides theoretical basis technical references integrated management rivers, grasslands, farmlands, mountains, lakes, sands LRB, well restoration other regions.

This study focuses on the Xiaoxing’an Mountains, examining evolution of ecological security patterns and suggesting optimization strategies by integrating carbon storage landscape connectivity, using multi-source data from 2000, 2010, 2020. The provides a comprehensive assessment region’s estimating stocks InVEST model, analyzing connectivity through MSPA, spatially extracting corridors nodes circuit theory. key findings are as follows: (1) High-value areas for primarily concentrated in southeastern northwestern forested mountain regions; (2) Ecological source predominantly southeast dispersed north, with total area peaking 2010 at 47,054.10 km2; (3) Northern dense, radiating spider-web pattern, pinch points corridor termini; sparse, mainly short, fewer points; (4) barriers increased 280% over past 20 years. Four major barrier zones were identified, all located junction forest farmland northwest, composed wetlands, drylands, rural residential areas; (5) Based evolutionary characteristics Security Pattern years, an “axis, two belts, four zones, multiple cores” planning framework was proposed, along corresponding strategies. theoretical support practical guidance enhancing regional network stability, optimizing strengthening sink functions.

Urbanization has significantly impacted ecological connectivity, making the optimization of networks (ENs) crucial. However, many existing strategies focus on overall network structure and overlook spatial concentration local processes flow (EPF), limiting effectiveness planning. This study proposes a novel EN framework based urban–rural gradient zoning to enhance connectivity from perspective EPF. The divides areas outside core urban zone (CUZ) into fringe (UFZ), interface (UIZ), natural rural (NRZ), applying tailored in each zone. These include increasing corridor redundancy, reducing resistance, expanding width alleviate EPF concentration. Using Jinan, mega-city China’s Yellow River Basin, as case study, this simulated changes over 20 years validated framework’s effectiveness. Optimization validation showed that land low-flow corridors 65% UIZ NRZ 5 km improved by 6.3%, addressing seven pinch points three barrier points. highlights importance optimizing ENs via support sustainable development protection policies.

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. And offers new insights aiming “patch–corridor–matrix” paradigms “patch–stepping stone–matrix” framework. It also provides feasible suggestions for balancing protection resource sustainability

The National Park of Hainan Tropical Rainforest (NPHTR) plays the crucial role an ecological barrier for Island. It also serves as a valuable repository tropical biological heritage world. scientific establishment security pattern (ESP) NPHTR is therefore essential ensuring robustness and stability this regional ecosystem, safeguarding biodiversity, promoting sustainable development. This study integrates ecosystem service functions (ESFs) sensitivity to identify sources (ESs) so that integrity promoted ensured. Ecological corridors (ECs) are established on basis minimum cumulative resistance (MCR) model circuit theory. We integrate ESs, nodes, construct ESP NPHTR. areas extreme importance in account 25.17% 25.47% its overall area, respectively, predominantly situated higher elevations eastern central regions. Further, ESs mainly distributed western region, specifically Ba Wangling (BWL), Jian Fengling (JFL), Ying Geling (YGL), covering area 1624.67 km2 (38.06% total area) After correction, 47 ECs with distance 870.9 km have been established, BWL YGL serving core areas. pinch- points cover 11.49 16.35 km2, primarily consisting man-made landscapes such farmlands buildings.
