基于DMSP/OLS夜光遥感的山东半岛城市经济参量时空模拟分析

夜间灯光亮度与夜间人类活动程度具有密切的关系,夜间灯光遥感数据能够在一定程度上反映地区社会经济发展现状。文中基于2000-2012年21期DMSP/OLS夜间灯光数据对山东半岛蓝色经济区社会经济参量开展研究分析。首先,利用夜光总量统计方法和标准差椭圆法分别在时间和空间上对研究区夜间灯光亮度进行分析;其次,分别构建夜间灯光与GDP等4种社会经济参量的线性回归模型,进行相关性的分析;最后,采用GDP等2种社会经济参量对研究区进行时空模拟分析。结果表明:夜光数据与地区的社会经济参量具有明显的线性相关性,能够在时间和空间上客观地反映地区城市经济的发展现状和空间分布特征。

Spatial and Temporal Simulation Analysis of Urban Economic Parameters of the Shandong Peninsula Based on DMSP/OLS Night-Time Light Remote Sensing

The brightness of nighttime lights is closely related to the human activities at night.The remote sensing data of night-time light can reflect the status of regional social and economic development to a certain extent.Based on the DMSP/OLS night-time light images from 2000 to 2012,this paper studies and analyzes the social and economic parameters of the Shandong Peninsula Blue Economic Zone.Firstly,the night-time light intensity of the study area is analyzed in time and space by using the night-time light total statistical method and the standard deviation ellipse method.Secondly,the linear regression models of four kinds of socio-economic parameters,such as nighttime lighting and GDP,are constructed separately for correlation analysis.Finally,the spatial and temporal simulation analysis of the study area is carried out using two kinds of socio-economic parameters including GDP.The results show that the luminous data has obvious linear correlation with the socio-economic parameters of the region,and can objectively reflect the development status and spatial distribution characteristics of the regional urban economy in time and space.
