摘要
贫困县经济发展与物流POI(Point of interest)空间耦合性关系研究对优化贫困县物流设施布局、平衡地区经济发展要素、助推“减贫摘帽”攻坚战具有重要意义.该文以中央苏区的4个国家级贫困县为研究对象,利用NPP-VIIRS夜间灯光和POI数据,从时空演化差异、空间自相关及相关因素分析等角度分析了研究区经济发展与物流POI空间分布的耦合协调机制.结果表明:研究区夜间灯光与物流POI数据的空间分布总体趋势相一致,耦合协调由“零散型”逐渐发展为“U型带状”分布特征;研究区2018年经济与物流发展空间耦合协调度较2016年整体提高0.296,局部地区动态演变差异明显;中央苏区耦合协调呈现“盆地塌陷式”发展特征,4个国家级贫困县处于盆地中心地带;空间耦合协调发展水平与交通路网、地形地貌、人口分布等多方面因素联系紧密,“脱贫攻坚”需要全方位考虑地区差异性.
Research on the coupling relationship between economic development and logistics space in poor counties is of great significance in optimizing the layout of logistics facilities,balancing the elements of regional economic development,and boosting the fight against poverty alleviation for poverty-stricken counties.Taking the four existing poverty-stricken counties in the Central Soviet Area as the research object,utilizing NPP-VIIRS Luminous remote sensing data and POI(Point of interest)data,the coupling and coordination mechanism of economic development and logistics POI spatial distribution in the study area is analyzed from the perspective of spatial and temporal evolution,spatial autocorrelation and related factors analysis.The results show that the night light remote sensing in the study area is consistent with the overall trend of spatial distribution of logistics POI data,coupling coordination gradually evolved from"fragmented type"to"U-shaped strip"distribution.The spatial coupling coordination degree of economic and logistics development in the study area in 2018 is 0.296 higher than that in 2016,and the dynamic evolution of local areas is obviously different.The coupling coordination of the Central Soviet Area presents the development characteristics of"basin collapse".The level of spatial coupling and coordinated development is closely related to various factors such as traffic road network,topography and population distribution,and"peace for poverty"needs to consider regional differences in all aspects.
