Ecological security pattern (ESP) represents a sound spatial arrangement of ecosystem occurring in landscape. The research on the optimization ESP aims to improve and restore functions by rationally allocating optimizing ecological elements based key issues. Constructing can enhance connectivity regional habitat patches, which is great significance for protecting restoring biodiversity, improving stability resilience, achieving sustainable development. However, it challenging task systematically resilience networks under attacks. Little has been done enhancing edge-based Based morphological analysis (MSPA), minimum cumulative resistance (MCR) greedy algorithm (GA) models, this study presents new method construct optimize ESP. Dongting Lake Basin China, typical region with rich complex landscape patterns, intensive human activities, taken as an example. results indicate that network improved its 51.62%, robustness against random attacks 41.13%, targeted 43.41%, relative initial network. Monte Carlo test verifies reliability solution. proposed be used finding structure best specific attacks, provides valuable decision-making reference land planning biodiversity conservation.

Constructing ecological security patterns (ESP) effectively maintains ecosystems' green, healthy, and sustainable development. The InVEST model Conefor software were utilized in this study to pinpoint sources (eco-sources) through a blend of landscape connectivity the importance ecosystem services (IES); resistance surface was constructed by synthesizing gravity minimum cumulative (MCRM), extracted corridors (eco-corridors) nodes. Ultimately, research built ESP for Xinjiang. findings showed that: (1) 14 eco-sources identified Xinjiang, spanning an area 2.13 × 105 km2; 32 eco-corridors extracted, including 9 important 23 general eco-corridors, comprising total length 1.26 104 km; 46 nodes(eco-nodes); (2) size more patches Xinjiang 2.82 km2, which accounted relatively small size, value generally average. overall level primary high, but spatial distribution uneven; (3) values vary significantly, with high-level surfaces primarily located Junggar Basin Tarim low-level covering most Xinjiang's natural reserves other areas. study's can provide some references constructing at provincial scale arid semiarid regions planning restoration

Constructing an ecological security pattern (ESP) is effective measure to ensure environmental safety and urban development. With the establishment of national civilization construction demonstration zone in China, higher requirements are put forward for biodiversity conservation. Previous studies have focused on identification ESPs, while few optimized ESPs based endangered species protection. This study took Yichang as research object, used geospatial data construct optimize ESPs. We identified sources through sensitivity assessment extracted corridors minimum cumulative resistance model. On this basis, innovatively introduced information, ESP discussed function zones order play a greater role The results showed that: (1) includes 12 with total area 2,186.34 km2, 30 length 1120.44 km 15 nodes. (2) optimization connects important nature reserves scenic tourist areas, bringing into corridor network. importance evaluation delineated 8 Level I focusing biological protection 22 II landscape construction. (3) divided conservation zone, control restoration spatial principles each clearly defined. can provide reference species-rich cities.

Accurate identification of key areas for ecological restoration is an important foundation orderly promotion territorial space. This study identified the in Kangbao County according to research paradigm “source – resistance surface construction corridor extraction”. First, source sites were and screened based on habitat quality modeling, morphological spatial pattern analysis landscape connectivity analysis. Then, base was constructed using ArcGIS software nighttime light data. Thereafter, corridors extracted pinch points barrier with Linkage Mapper plug-in. Forty a total area 68.06 km 2 County. These dominated by woodland grassland, integrity these still needed be improved. The 96 (total length 743.81 km) identified, which densely distributed south east parts area, there much room improvement connectivity. Additionally, 75 31.72 ) 69 obstacles 16.42 identified. restored mainly Yan Yufang, Har Chimega, Tuchengzi, Zhangji, Danchenghe Townships. can lay firm
