Information Diffusion Interpolation Model Based on the PSO-CV Algorithm and Its Application on Source Regions of the Yellow River by HUANG Huaping, YIN Kaixia, JIN Gaoyang

“…The spatial interpolation based on the limited observation data of precipitation stations is an effective means to explore the spatial characteristics of precipitation.This paper briefly introduces a spatial interpolation model based on the information diffusion theory,proposes an optimal information diffusion interpolation model based on particle swarm optimization (PSO) and cross-validation (CV) with consideration of the disadvantages on key parameter estimation of existing experience information diffusion interpolation model,and evaluates the interpolation effect of the information diffusion interpolation model in terms of four time scales of year,quarter,month and day with inverse distance weighting,ordinary kriging method,universal kriging method and co-kriging method considering the elevation as comparison,taking the source regions of the Yellow River as an example.The results show that overall,the optimal information diffusion interpolation model has the highest accuracy,while the inverse distance weighting has the lowest accuracy.The accuracy of experience information diffusion interpolation model does not differ much from the other three spatial interpolation methods,and the accuracy differences between different methods decrease as the time scale decreases.…”

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.…”
