Construction and optimization of ecological security patterns in ecologically fragile areas: a case study of Lanzhou City, China by Jianhong Dong, Lina Li, Wenjin Yang, Benteng Liu, Xinhong Zhang

“…Third, the Minimum Cumulative Resistance (MCR) model, GIS Hydrological Analysis module and Spatial Analysis module were used to divide ecological suitability zones, determine ecological corridors, and identify ecological nodes, so as to construct ESPs and propose optimization strategies.ResultsThe results showed as follows: 1 Spatial differentiation of ecological sources (1388.73 km2, 10.61%) predominantly in northwestern and southern regions, contrasting with urban sources (527.66 km2, 4.03%) concentrated along the Yellow River Valley and Qinwangchuan Basin; 2 According to the MCR difference between ecological sources and urban sources, the study area was divided into ecological core zone (ECZ), ecological buffer zone (EBZ), optimized construction zone (OCZ), and suitable construction zone (SCZ), with the proportions of 37.05%, 25.68%, 18.53% and 18.74%, respectively; 3 Based on the theory of “matrix - patch - corridor - node” in landscape ecology, the ESPs of Lanzhou City was constructed with the framework of “One belt, Two rings, Four screens, Six districts and multiple corridors”.DiscussionThe results can provide reference for ecological environment protection and ecosystem restoration in the upper reaches of the Yellow River Basin in China.…”
