宁夏开发区土地集约利用时空分布特征与驱动因素分析
Spatial and temporal distribution characteristics and driving factors of land intensive utilization in development zones of Ningxia
摘要
Abstract
The intensive utilization of land within development zones is crucial for the region's high-quality de-velopment in the new era,with its dynamics emerging as a prominent research area.This study,focusing on the development zones of Ningxia,China,investigates the spatio-temporal distribution of land use intensification from 2018 to 2021.It identifies key influencing factors such as economic quality,innovation drive,open environ-ment,green transformation,and structural optimization,employing the geographically and temporally weighted re-gression(GTWR)model to delineate the underlying drivers of intensive land use.The findings reveal that:(1)Land use intensification in Ningxia's development zones exhibits a distribution pattern where the northern Yellow Riv-er irrigation area surpasses the central arid area,which in turn surpasses the southern mountainous area,with the disparity between these areas decreasing over the study period.(2)The GTWR model proficiently captures spa-tial and temporal variations in the driving mechanism,highlighting green transformation and structural optimiza-tion as primary influencers,followed by innovation drive and economic quality.(3)The impact of each factor on land use intensification exhibits significant spatial and temporal heterogeneity;for instance,the growth rate of fixed asset investment exerts a more pronounced influence in the northern Yellow River irrigation area,while the growth rate of industrial enterprises'total income is more influential in the central and southern regions.More-over,the effect of land consumption per unit of industrial income on intensification levels slightly diminishes,with the influence of other factors gradually intensifying.This study elucidates the dynamic mechanisms of inten-sive land use across different development zones,aiming to inform land use policy and support the development of high-quality zones in the western Yellow River Basin.关键词
