Ecological Indicators, Journal Year: 2024, Volume and Issue: 159, P. 111647 - 111647

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

Linking endangered species protection to construct and optimize ecological security patterns in the National ecological Civilization construction Demonstration Zone: A case study of Yichang, China

Ecological Indicators, Journal Year: 2024, Volume and Issue: 158, P. 111579 - 111579

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.
