摘要
长江中游城市群是中国高质量发展的重要增长极,识别该区域不同经济发展梯度下国土空间格局演变的时空特征及驱动力,对于优化国土空间格局、推动区域协调发展具有重要意义。借助国土空间转移矩阵、标准差椭圆、核密度分析、空间计量模型等方法,揭示1990~2020年长江中游城市群不同经济发展阶段下国土空间格局演变特征及驱动机制。主要结论如下:(1)长江中游城市群国土空间类型主要占比从高到低依次为生态空间、农业空间、城镇空间;不同发展阶段下国土空间格局变化特征存在显著差异。(2)城镇-农业-生态空间互竞形成了“一增双减”的国土空间格局,且随着经济发展阶段的提升,不同国土空间类型间呈现出更加繁杂多样的转换模式,耕地、绿地也越容易流失。(3)城镇空间由主核数量较少且集聚特征不明显转变为多核扩散且高值区增加,重心变化较为剧烈;农业空间次核数量增加,高值区域明显减少,空间破碎化程度较高,重心变动较为稳定;生态空间的核密度由空间集中转变为空间破碎,西北地区变化较为明显。(4)国土空间格局形成受到自然、人口、经济等多重因素驱动,各因素对不同空间的影响程度及方向存在差异。应充分考虑长江中游城市群未来发展定位,加强国土空间分类管理,协调国土空间格局各驱动因素,以期为新时代长江中游城市群“三区”空间协调健康可持续发展提供理论依据和决策参考。
The Yangtze River Midstream Urban Agglomeration is an important growth pole for China's high-quality development.Identifying the spatiotemporal characteristics and driving forces of land spatial pattern evolution under different economic development gradients in this region is of great significance for optimizing the land spatial pattern and promoting regional coordinated development.This study utilized methods of land spatial transfer matrix,standard deviation ellipse,kernel density analysis,and spatial econometric models to reveal the characteristics and driving mechanisms of land spatial pattern evolution in the study area,during the period of 1990-2020.The main conclusions were as follows:(1)The proportions of different land spatial types in the study area were ranked from high to low in terms of ecological space,agricultural space,and urban space.The changes in land spatial pattern varied significantly under different development stages.(2)The competition among urban,agricultural,and ecological spaces formed a land spatial pattern of"increase in one,decrease in two".The improvement of economic development stages,the transformation patterns among different land spatial types became more complex and diverse.The farmland and green space were more prone to loss.(3)The urban space changed from a small number of main cores and unclear agglomeration characteristics to multiple core diffusion and an increase in high-value areas,with more drastic changes in the center of gravity;The agricultural space demonstrated an increase in the number of sub-cores,a significant decrease in high-value areas,a higher degree of spatial fragmentation,and a relatively stable change in the center of gravity;The kernel density of ecological space changed from spatial concentration to spatial fragmentation,especially in the northwest region.(4)The formation of land spatial pattern was driven by multiple factors including nature,population,and economy.The degree and direction of these factors'influence on different spaces varied.According to this study,it was necessary to fully consider the future development orientation of the Yangtze River Midstream Urban Agglomeration,strengthen land spatial classification management,and coordinate the driving factors of land spatial pattern,in an attempt to provide theoretical basis and decision-making reference for the coordinated,healthy,and sustainable development of the"three zones"in the study area in the new era.
