中原城市群城乡建设用地时空变化及其驱动力分析

Analysis of the Spatiotemporal Changes and Driving Forces of Urban and Rural Construction Land in the Central Plains Urban Agglomeration

以中原城市群的新乡、鹤壁和安阳为研究区域,利用ENVI5.3和ArcGIS 10.2软件,结合Landsat 8 OLI_TIRS卫星遥感数据,分析2013年、2017年和2021年这3个时间节点的城乡建设用地变化。经研究发现,2013—2021年间,研究区域建设用地面积显著增长,其中,2017—2021年的增长速度尤为显著。通过对比分析和转移矩阵方法,揭示了建设用地扩张与区域经济发展、人口增长、城市化进程等因素的密切关联。研究结果可为区域土地资源管理和城乡规划提供参考。

Taking Xinxiang,Hebi and Anyang of the Central Plains urban agglomeration as the research area,using ENVI5.3 and ArcGIS 10.2 software along with Landsat 8 OLI_TIRS satellite remote sensing data,this article ana⁃lyzes the changes in urban and rural construction land at three time points in 2013,2017,and 2021.The study re⁃veals a significant increase in construction land area from 2013 to 2021,with the growth rate between 2017 and 2021 being particularly noteworthy.Through Comparative Analysis and Transition Matrix methods,the close con⁃nection between the expansion of construction land and regional economic growth,population increase,and urban⁃ization processes,and other factors has been revealed.These study results can provide reference for regional land re⁃source management and urban-rural planning.
