中文摘要:粤港澳大湾区是我国改革开放程度最高,经济活力最强的区域,探究其城市化时空特征对理解区域城市群演变及经济发展关系具有重要意义。本研究利用1992—2012年DMSP/OLS与2012—2021年NPP/VIIRS两套夜间灯光遥感数据,通过对比两种数据整合路径(基于NPP/VIIRS模拟DMSP/OLS与基于DMSP/OLS模拟NPP/VIIRS)的效果,并借助其与国内生产总值(Gross Domestic Product,GDP)的线性回归分析验证数据可靠性,最终遴选出最优的数据融合方案,构建了1992—2021年粤港澳大湾区长时间序列夜间灯光数据集,并探究了大湾区城市化的时空演变规律。结果表明:(1)1992—2021年粤港澳大湾区夜间灯光亮度整体上呈持续增长趋势,且其灯光亮度增长在1992—2001年、2002—2011年和2012—2021年3个时间段有显著的地域差异,首先经历广州、香港、澳门等核心城市辐射带动周围城市核心区灯光亮度快速增长,随后溢出到郊区,并刺激郊区快速增长,当郊区发展饱和后,灯光效应再次溢出至县域乡镇地带;(2)1992—2021年粤港澳大湾区北部、西部城市建成区扩张速率高于东部、南部,且粤港澳大湾区城市建成区向外扩张的主要方向逐渐由“东南—西北”方向转变为“偏东—偏西”方向。
外文摘要:The Guangdong-Hong Kong-Macao Greater Bay Area(GBA)stands as a paramount symbol of China's reform and opening-up,characterized by its exceptional economic vitality.Understanding its spatiotemporal urbanization patterns is crucial for deciphering the evolution of mega-city clusters and their interplay with economic development.To address the inconsistencies between DMSP/OLS(1992—2012)and NPP/VIIRS(2012—2021)nighttime light data,this study constructed a continuous,long-term dataset by evaluating two integration approaches:simulating DMSP/OLS from NPP/VIIRS and vice versa.The optimal method was selected based on the performance of linear regression models with Gross Domestic Product(GDP),resulting in a consistent nighttime light dataset(1992—2021)for the GBA that shows a higher consistency with socioeconomic indicators.Our analysis revealed that:(1)From 1992 to 2021,the nighttime light intensity in the GBA showed a continuous increasing trend,with distinct spatial dynamics across three periods:initial rapid growth was concentrated in the core urban areas of Guangzhou,Hong Kong,and Macao(1992—2001);subsequently,the growth hotspot diffused into the suburbs(2002—2011);and finally,it expanded further into county-level towns and rural areas(2012—2021).(2)The expansion rate of urban built-up areas was higher in the northern and western parts of the GBA than in the eastern and southern parts.Moreover,the primary direction of urban expansion underwent a notable shift,transitioning from a“southeast-northwest”orientation to a predominantly“east-west”orientation.
