Spatio-temporal evolution analysis of land use and ecological risk in southern Taihang Mountains from 2010 to 2023
摘要
Abstract
As a critical ecological barrier zone in the North China Plain,the land use changes in the southern Taihang Mountains have significant impacts on regional ecological security and coordinated development.Using methods such as the land use dynamic degree and land use transfer matrix,this study analyzed the spatiotemporal characteristics of land use changes in the southern Taihang Mountains.A 5 km×5 km grid was employed to establish ecological risk assessment units,and an ecological risk evaluation system was con-structed by integrating landscape vulnerability,disturbance,and loss indices to analyze its spatiotemporal evolution.Moran's I index was used to examine spatial autocorrelation.The results show that from 2010 to 2023,the southern Taihang Mountains region primarily exhibited a structural transformation of ecological land into construction land.The total area converted to construction land was 984.61 km²,of which farmland conversion accounted for 940.63 km²,representing 95.53%of the total conversion.Meanwhile,farmland was supplemented by forests,grasslands,and water bodies,but the scale of such replenishment was small and far below the converted area,resulting in a net reduction trend.Overall,ecological risk displayed a pattern of"high-risk areas shrinking and medium-high-risk areas expanding".The"high-high"risk clusters were mainly concentrated in the transitional zone between the central-eastern plains and hills,where frequent human disturbances led to contiguous diffusion.In contrast,"low-low"risk areas remained stably distributed in the forested and well-shrub-covered mountainous regions of the west.关键词
