【摘要】 文章通过对安徽省20世纪90年代以来各城市货运量变动情况的分析,运用地域非均衡系数、位势商及地理联系率指标,总结得出近十五年来安徽省货流运输联系的基本特征及其时空演化趋势。自1990年以来,安徽省货流运输能力显著增强、运输结构不断优化、货运强度和货物生成密度持续下降,地区间运输联系逐步加强。在时间序列上,货运量分布表现出均衡化趋势,地域分布非均衡系数不断减小,同时,货运量分布区域位势高低悬殊,而且各城市的波动比较明显。在空间演化方面,货运量分布与生产地分离的趋势已经显现。更多还原

【Abstract】 With analyzing into changes of goods transportation volume in Anhui province 1990′s and using indexes of Coefficient of non-balanced and Coefficient of geographic association,the author summarizes essential features and space-time evolution trend of Anhui freight transportation connection in fifteen years.From the 1990′s,freight transportation capacity is notable strengthened,transportation structure is continuously optimized,freight transportation intensity and goods generation density is steady declined,and regional transportation connection is progressively strengthened.In time series,the distribution of goods transportation showing balanced trend,coefficient of non-balanced is increasingly declined,at the same time,regional geo-potential of freight distribution differs widely and fluctuates obviously.In the aspect of spatial evolution,the separative trend between distribution of goods volume and production location is appeared.更多还原
