摘要:

快速城市化改变了下垫面物理性质和地气相互作用,影响了气候及环境变化,如何通过合理的时空尺度对我国城市过程进行监测与认知是我国城市化发展战略的迫切需求。以京津冀城市群为研究区,利用改进的夜晚灯光指数(VANUI)对京津冀城市群2001~2012年的城市化发展过程进行了监测,对比了VANUI指数与传统夜间灯光指数对城市区域的监测能力差异及其优势所在,为京津冀地区未来城市化发展战略规划服务。结果表明,VANUI城市指数能很好地弥补夜晚灯光指数在城市区域饱和的缺陷,并能够较好地反映城市区域的空间格局及相应的细节信息。根据VANUI结果,2001~2012年间京津冀城市群扩张了约一倍,其中城市扩张速度最快的为河北省唐山市。从整个研究区域来看,在此10年间,VANUI以接近线性的发展趋势增加,从统计结果来看,2004~2007年及2009~2012年为研究区域VANUI普遍增长的时期。

Abstract:

Rapid urbanization has changed land surface properties and land-atmosphere interaction,which further may impact on the climate and environment.It is important for urban sustainability to timely and accurate monitor regional or global urbanization process.Currently,urban area in large scale could be derived from satellite images,and DMSP/OLS has already been widely used to detect global urbanization due to its time series.However,its saturation in urban area largely limited its further application.Therefore,an improved urban index (VANUI) was used to detect urbanization process in JING-JIN-JI area from 2001-2012 to examine its fitness in mega-city area,further provide reasonable information for urban planning and urban sustainability.Compared with the traditional night lights index,VANUI is indeed to improve the monitoring ability for urban center and reduce the influence of signal saturation on parameters derivation.The results showed that VANUI could catch the urbanization process that happened in JING-JIN-JI area during last decades.Spatial pattern of urban expansion from 2001-2012 indicated that the urban area of JING-JIN-JI was doubled from 2001-2012,and the fasted region about urbanization happened in Tangshan,Hebei Province.Linear trend was also detected in urban development by VANUI index from 2001-2012,and the most important increasing period showed in 2004-2007 and 2009-2012.
