基于NPP/VIIRS的山东省经济发展时空演化研究
Study on the Spatio-temporal Evolution of Economic Development in Shandong Province Based on NPP/VIIRS
摘要
Abstract
Shandong Province has an important strategic position in the national economic construction and industri-al development.The analysis of the economic development law and the spatio-temporal evolution characteristics of Shandong Province is of far-reaching significance to the promotion of the north-south linkage and the implementa-tion of the"the Belt and Road".Based on the NPP/VIIRS nighttime light data from 2014 to 2022,the nightlight statistical index and weighted standard deviation ellipse were calculated to monitor the development trend and di-rectional changes in the province.Considering the correlation between the covered degree and the intensity of night light,the principal component analysis method combined with the NDVI(Normalized Difference Vegetation Index)was used to establish an economic development evaluation model,to analyze the spatial economic pattern of Shan-dong Province.The results show the following three aspects.1)The total intensity of night light in the province is steadily increasing,with Jinan,Qingdao,Weifang,and Linyi growing significantly,and Taian,Dezhou,and Heze growing rapidly,with growth rates of more than 190%.2)The main direction of economic development re-mains"Southwest-Northeast",with dispersion in both primary and secondary directions,and the standard deviation ellipse flatness stabilizes at 0.43～0.44,making the economic center of gravity relatively stable.3)The nighttime lighting indicator model combined with NDVI has a better correlation with socio-economic indicators,with Qingdao occupying the first place in terms of development among prefecture-level cities,Jinan,Linyi,Weifang,and Yantai in good condition,the rest of the regions lagging comparatively.The research results further reveal the economic development law of Shandong Province,which can provide data support and a reference basis for future decision-making planning and pattern cognition.关键词
