Anthropogenic activities amplify spatiotemporal variations in regional ecological security patterns dominated by natural factors: Evidence from the West Liaohe River Basin, China
Randomized trial explores ecological security patterns, emphasizing anthropogenic influences in a regional context.
Key Points
This study aims to investigate the spatiotemporal variations in ecological security patterns influenced by both natural and anthropogenic factors in the West Liaohe River Basin.
Analyzed five key ecosystem services from 2000 to 2020 in the West Liaohe River Basin.
Employed the Geodetector model to measure explanatory rates of factors affecting ecological sources and corridors.
Utilized the Geographically and Temporally Weighted Regression model to examine driving mechanisms.
Natural factors explained 23.86% of the spatial distribution of ecological sources and corridors.
Anthropogenic activities accounted for 13.29% but amplified spatiotemporal variations.
An ecological security protection strategy was proposed focusing on regional priority, suitability analysis, and risk regulation.
