土地作为经济活动的承载体,其开发利用水平关系经济高质量发展.该研究借助趋势分析法、变异系数法分析土地集约利用与城市化协调作用空间差异性,通过ArcGIS与GeoDa探讨协调作用空间自相关性,并分析协调作用的障碍因素.结果表明:2010年中度失调集中在中部,轻度失调集中在东南沿海与西部,濒临失调和勉强协调集中在京津冀地区;2021年轻度失调集中在西部,濒临失调和勉强协调集中在中部,初级协调、中级协调在东部.协调作用变异程度较稳定,全局莫兰指数(Moran's I)表明协调作用在空间上存在显著稳定的正向关联特征.2010年京津冀地区为明显的高高集聚类型,广东为明显的高低集聚类型;2021年上海与江苏为新增的高高集聚类型,新疆、青海、四川与云南为新增的低低集聚类型.京津冀地区、东南沿海协调作用的障碍因素集中在经济水平、产业结构与建设用地面积,但影响程度不同.
Analysis on spatio-temporal changes and obstacle factors of the coordination between land intensive use and urbanization
As the carrier of economic activities,the development and utilization level of land is related to the high-quality development of economy.In this study,the spatial differences between land intensive use and urbanization coordination were analyzed by trend analysis and coefficient of variation method.The spatial autocorrelation of coordination was discussed by ArcGIS and GeoDa,and the obstacle factors of coordination were analyzed.The results showed that in 2010,the moderate disorder was concentrated in the central region,the mild disorder was concentrated in the southeast coast and the west,and the borderline disorder and the reluctant coordination were concentrated in the Beijing-Tianjin-Hebei region.In 2021,the mild disorder was concentrated in the west,borderline disorder and reluctant coordination were concentrated in the middle,and primary and intermediate coordination were concentrated in the east.The degree of variation of coordination effect was stable,and the global Moran's index showed that coordination effect has a significant and stable positive correlation feature in space.In 2010,the Beijing-Tianjin-Hebei region had an obvious high and high cluster type,while Guangdong had an obvious high and low cluster type.In 2021,Shanghai and Jiangsu were the new types of high and high cluster type,and Xinjiang,Qinghai,Sichuan and Yunnan were the new low and low cluster type.The hindrance factors of coordination in Beijing-Tianjin-Hebei region and southeast coastal area are concentrated in economic level,industrial structure and construction land area,but the impact degree is different.
