摘　　要：本文通过对1992—2013年全国夜间灯光数据的校正和处理,获得全国及流域夜间灯光数据影像,进行经济空间聚合分析,以及与相关因子进行对比分析。研究结果表明:经济空间聚合高的区域分布在黄河河道附近,从黄河上游到下游,热力强度逐渐增强,并且以省会城市为核心区向外扩散,即呈现为在旧聚合点聚合度加剧的情况下,聚合区域有向周边分散的趋势;夜间灯光数据的变化趋势与GDP的变化趋势具有一定的相似性,并且与城镇化率、人口数量、第三产比例、人均公园绿地面积、流域发展指数(BDI)具有一定的相关性;流域9省(自治区)的夜间灯光数据整体变化趋势与全国灯光数据的变化趋势基本一致,呈稳定上升的趋势,但整体值均低于全国的夜间灯光数据,并且差距有所扩大,黄河流域高质量发展迫在眉睫。Through the correction and processing of the national nightlight data from 1992 to 2013, this paper obtains the national and watershed nightlight data images, conducts economic spatial aggregation analysis, compares and analyzes the relevant factors. The results show that the areas with high economic spatial aggregation are distributed near the Yellow River channel, from the upper reaches to the lower reaches of the Yellow River, the heat intensity is gradually increasing, and the provincial capital city is the core area, spreading outwards, showing the tendency of the polymerization area to disperse to the surrounding area under the condition that the polymerization of the old polymerization point is intensified. The basin development index BDI has a certain correlation, the overall trend of nightlight data in 9 provinces of the basin is basically consistent with the change trend of the national nightlight data, showing a steady upward trend, but the overall value is lower than the national nightlight data, the high-quality development of the Yellow River Basin is imminent.
