摘要
获取长时间序列的城市发展状况对于合理规划城市、解决城市化问题具有重要意义。美国国防部气象卫星DMSP上搭载的线性扫描业务系统传感器OLS可以获取一个城市多年的夜间灯光数据。基于DMSP/OLS夜间灯光数据,本研究以山西省典型城市(太原市、大同市和运城市)为研究区,按照5年为1个时期,分析了典型城市在1992-2013年期间不同时期的夜间灯光亮度变化状况,并与GDP变化进行对比,从而获取3个城市在过去20多年的发展状况。研究结果表明:太原市经济基础最强,在发展速度上呈现持续快速发展态势,是整体实力最强和发展态势最好的城市;大同市经济基础次之,在前3个时期发展速度缓慢,后2个时期开始快速发展;运城市经济基础最差,但呈现持续高速发展态势,是3个城市中整体发展速度最快的城市。
Acquiring city development situations at long time series is meaningful for rational planning of the city and resolving urbanization issues.The Operational Line Scan System(OLS)sensor aboard on the Defence Meteorological Satellite Program(DMSP)can acquire night time light image at long time series.Taking typical cities of Shanxi Province(Taiyuan City,Datong City,and Yuncheng City)as the research regions,this research analysed the spatial distribution change of brightness value for DMSP/OLS data at five years period from 1992 to 2013,so as to understand the development progress during the past 20 years for the three cities.Research results show:Taiyuan City has the strongest economic foundation,and presents continuous quick developing speed,so it is the city with the strongest and best developing trend city;Datong City has less economic foundation,which develops slowly in the previous three periods,but starts fast development in the latter two periods;Yuncheng City has the least economic foundation,but presents a developing tendency with continuous fast speed,and thus has the quickest development speed in the three cities.
