摘要
采用关注比重变化的强度分析方法识别1990-2020年的广佛都市圈土地利用变化,该方法具有极强的信息挖掘能力,能够弥补传统方法的不足。同时采用PLUS模型分析该区域土地利用变化的驱动力。结果表明:1990-2020年广佛都市圈土地利用变化经历了缓慢-快速-缓慢的过程,2000-2010年是其他时间间隔变化强度的两倍。建设用地的转入强度稳定活跃;耕地的转出强度稳定活跃;水域面积在2000年后出现大幅减少。对于建设用地的增加,耕地稳定趋向于转为建设用地,水域由避免转为趋向,林地却是稳定避免的。根据驱动力分析结果显示,广佛都市圈的土地利用变化主要受到社会经济因素的驱动。研究对都市圈规划和土地利用政策制定具有借鉴意义。
This study employs an intensity analysis method focusing on proportional change to identify land-use conversion in the Guangzhou-Foshan metropolitan area from 1990 to 2020.This approach demonstrates strong information extraction capabilities and can compensate for the limitations of traditional methods.Meanwhile,the PLUS model is used to analyze the driving force of LUCC in this region.The results indicate that land-use conversion in the Guangzhou-Foshan metropolitan region from 1990 to 2020 underwent a slow-fast-slow transition process,with the change intensity during 2000-2010 being twice that of other periods.Construction land exhibited consistently high intensity in land gain;cultivated land showed stable and active intensity in land loss;Water bodies experienced a sharp decline after 2000.Regarding the expansion of construction land:cultivated land consistently tended to be converted into construction land;water bodies shifted from avoidance to a tendency for conversion;forest land,however,remained consistently avoided.Driving force analysis reveals that land-use conversion in the Guangzhou-Foshan metropolitan region were primarily driven by socioeconomic factors.This study provides valuable insights for metropolitan planning and land-use policy formulation.
