Climate change and land use change caused by human activities have a profound impact on ecological security. Simulating the spatio-temporal changes in ecosystem service value and ecological security patterns under different carbon emission scenarios in the future is of great significance for formulating sustainable development policies. This study quantified the four major ecosystem services (habitat quality, water retention, soil erosion, and carbon storage) in Northeast China (NC), identified ecological source areas, and constructed a stable ecological security pattern. The results show that the spatial patterns of soil erosion, carbon storage, water retention, and habitat quality, the four major ecosystem services in NC, are relatively stable in the next 30 years, and there is no significant difference from the current spatial pattern distribution. The SSP1–2.6 carbon emission scenario is a priority model for the development of NC in the next 30 years. In this carbon emission scenario, the NC has the largest ecological resources (191,177 km2) and the least comprehensive resistance value (850.006 × 10−4). At the same time, the relative resistance of the corridor in this scenario is the smallest, and the area of the mandatory reserve pinch points is the least. The ecological corridors in the SSP1–2.6 scenario form a network distribution among the ecological sources, connecting several large ecological sources as a whole. This study fills the knowledge gap in building a stable ecological security pattern in NC under the background of global change, and provides a scientific basis for the decision-making of regional ecological security and land resource management.

“…Hence, this region should be designated as a strictly protected area. At the edge of this area where it meets urban land, buffer zones should be established, adhering to the avoidance distance and foraging range of small mammals (200-300 m) (Chen et al, 2002;Gao et al, 2021;Luo & Fu, 2023) to reduce human interference with population dispersal. Simultaneously, the core zone within this area should be restricted from access and incorporate a multi-level vertical structure of vegetation communities and serrated forest edge spaces (Fergus, 2019) to provide diverse shelter options for small mammals, thereby achieving ecological nurturing goals.…”

In the context of rapid urbanization, protecting landscape connectivity has become an effective measure to mitigate habitat fragmentation and curb biodiversity decline. However, in the current research on simulating optimization processes, the ecological constraints often set are dispersed, isolated, and fixed. They fail to form a comprehensive protective spatial framework and struggle to align with the multifaceted objectives of future development. This study, taking the main urban area of Hangzhou, China as a case study and employing small mammals as indicator species, utilizes the PLUS model to predict the potential threats to landscape connectivity of biological habitats posed by artificial surface expansion from 2020 to 2035. It constructs a coupled mechanism that integrates multi‐level ecological security patterns (ESPs) and multi‐scenario simulation for landscape connectivity, successfully demonstrating the effectiveness of this mechanism in future landscape connectivity preservation. The results indicate that under the scenarios of business‐as‐usual (BAU), priority given to urban development (PUD), and priority given to ecological protection (PEP), the overall level of landscape connectivity in the main urban area of Hangzhou is projected to decrease by 18.42%, 7.02%, and 4.39% respectively from 2020 to 2035. The reduction in core area is estimated to be 9.08%, 7.85%, and 6.34%, respectively, while highly important patches are expected to decrease by 12.91%, 7.51%, and 5.86%, respectively. Both PEP and PUD scenarios effectively mitigate the degree of landscape connectivity disruption. This study provides valuable insights for the future optimization of landscape connectivity and contributes to biodiversity conservation efforts.

“…However, extensive economic development and outdated concepts of ecological environmental protection have introduced various ecological problems (Bai et al, 2022). Various countries around the world are attempting to improve the quality and function of ecosystems by developing ecological and environmental protection technologies and planning schemes (Zha et al, 2021;Luo and Fu, 2023). However, the problems of landscape fragmentation, biodiversity loss, and ecosystem service degradation have not been effectively contained (De León et al, 2019;Dai, 2022).…”

“…Such efforts are of great significance for the stable improvement of ecosystem services and high-quality economic development on the island. Previous studies on the ecological security of Hainan Island involved only some regions (Han et al, 2022) and certain ecosystem types (Luo and Fu, 2023), or only considered ecological planning from the perspective of biodiversity (Lei et al, 2022). In particular, systematic Frontiers in Environmental Science frontiersin.org research on the whole island is lacking, especially on ESPs coupling multiple ecosystem service functions.…”

The identification and restoration of damaged ecosystems are key to achieving ecological conservation and sustainable. Hainan Island is experiencing a serious crisis of biodiversity and habitat degradation. Therefore, its ecological conservation has become a priority and challenge for China. This study aimed to construct a multi-level ecological security pattern (ESP) based on the synergy of multiple ecosystem service functions and identify important ecological elements and ecological restoration areas. Based on the InVEST model, the circuit theory model, and a series of GIS spatial analysis methods, the importance of ecosystem functions (biodiversity maintenance, water conservation, carbon sequestration, and soil conservation) was evaluated, and ecological sources, ecological corridors, ecological pinch points, and ecological barrier points were identified. The results are as follows: 1) The best habitats in Hainan Island were distributed in the central mountainous area with diverse ecosystems, with an area of 10982.5 km2, accounting for 34.25% of the total suitable habitats. Low-level habitats are mainly distributed on tableland and coastal zones. Human disturbance is the direct cause of landscape patch fragmentation in low-level habitat areas. 2) A total of 65 large ecological sources with a total area of 8238.23 km2 were identified, which were concentrated in the biodiversity and water conservation areas in the central part of the island. 3) Crucial areas in Hainan Island mainly comprised forests and water bodies. Ecological corridors radiated across the entire area in the form of a spider web and connected all important ecological patches, including 138 ecological corridors (73 primary ecological corridors and 65 secondary ecological corridors), 222 ecological pinch points, and 198 ecological barrier points. In addition, the identified areas for restoration are primary areas in urgent need of protection and restoration. In general, the ecological pinch points are natural conservation areas supplemented by anthropogenic restoration, and the ecological barrier points demand equal attention for anthropogenic restoration and nature conservation. The ecosystem protection plan developed in this study will enrich the theoretical achievements of territorial spatial ecological planning in Hainan Island, and provides clear guidance for alleviating the contradiction between land use and economic development in Hainan Island.
