【摘要】：基于1993~2012年长时间序列夜光遥感数据,利用空间统计、空间标准差椭圆和位序-规模分布方法研究"一带一路"(the Belt and Road Initiative,BR)沿线国家的城市体系空间结构和时空演化趋势。结果表明:"一带一路"沿线各国城市夜间灯光增长最快的是进行经济改革的发展中国家和战后重建的国家,城市夜间灯光锐减主要发生在社会经济动荡地区。"一带一路"区域内城市夜间灯光的规模分布总体呈现空间扩张趋势,夜间灯光重心向东南亚方向移动。"一带一路"区域内城市夜光规模前2 000位的城市夜间灯光符合位序-规模准则,高位序城市夜间灯光规模不够突出而中小城市发育相对较好,集中趋势大于分散趋势。
[Abstract]:Based on the long time series of night light remote sensing data from 1993 to 2012, spatial statistics, spatial standard deviation ellipse and location-scale distribution method are used to study the spatial structure and space-time evolution trend of urban system in the countries along the "Belt and Road" and the Belt and Road Initiative. The results show that the cities along Belt and Road have the fastest night lighting growth in the developing countries and the post-war reconstruction countries, and the sharp decrease of the urban night lighting mainly occurs in the areas of social and economic instability. " Belt and Road, "the size distribution of urban nighttime lighting in the region shows a general trend of spatial expansion, and the center of gravity of nighttime lighting moves to Southeast Asia." In Belt and Road region, the urban night lighting in the top 2 000 places accords with the order scale criterion. The high order city night light scale is not prominent enough, but the small and medium-sized cities are relatively well developed, and the concentration trend is larger than the dispersion trend.
