摘要
基于“格局—过程—影响—可持续性”的研究思路,探究了2000—2018年京津冀都市圈内“三生”空间变化及其驱动力。研究表明:都市圈内“三生”空间变化显著,各用地类型间发生了复杂的土地利用转移,其复杂性体现在不同时期内地类主要的转化方向和速度不同,以及同一时期不同地点的转化方向不同;都市圈内生产空间减少,生态空间和生活空间增加,生产空间大量转为生活空间是土地利用转移的主要趋势;京津冀都市圈“三生”空间分布呈“双轴一主一副”格局且较为稳定;通过主成分分析法得出,人口增加和经济发展、农业技术进步和农业效益低下是推动“三生”空间变化的主要驱动力。制约“三生”空间可持续利用的主要问题分别为耕地严重流失和农村生活用地比重过大,应通过基本农田保护、农业技术革新以及土地整治等政策规划和技术的提升优化“三生”空间利用与布局。
Based on the thinking of“pattern-process-influence-sustainability”,this paper explores the spatial-temporal changes and driving forces of“production-living-ecological”spaces in Beijing-Tianjin-Hebei Metropolitan Area from 2000 to 2018.The research shows that the spatial change of“production-living-ecological”spaces in the metropolitan area is significant,and the complex land use transfer occurs among different land use types.The complexity is reflected in the different transformation directions and speeds of the main land use in different periods,and the different transformation directions of different locations in the same period.The main trend of land use transfer is the decrease of production space,the increase of ecological space and living space,especially,the transformation of production space into living space.The spatial distribution of“production-livingecological”spaces is“two axes,one centre and one sub-centre”and relatively stable.Through principal component analysis,it is concluded that population increase and economic development,agricultural technological progress and low agricultural efficiency are the main driving forces to promote the spatial change of spaces.The main problems that restrict the sustainable use of“production-living-ecological”spaces are the serious loss of cultivated land and the excessive proportion of rural living land,so the utilization and distribution of them should be optimized through the protection of basic farmland,agricultural technological innovation,land consolidation and other policy planning.
