摘　　要：采用因子分析将公路运输枢纽载体城市的14项统计指标简化为3类综合因子,构建Koho-nen网络模型并输入综合因子变量得到公路运输枢纽的初步分类方案,通过F-统计量检验分类效果发现将所选44个公路运输枢纽分为4类最佳.结果表明,因子分析与Kohonen网络结合是一种有效的公路运输枢纽分类方法,公路运输枢纽具有较明显的4个层级结构.Three synthetic factors were synthesized from 14 indices of highway transportation hubs by factors analysis, and were regarded as input indices of Kohonen network model. Authors acquired preliminary classifications of 44 Chinese highway transportation hubs with neural network model. After F -statistical was used to test the preliminary classifications, 44 Chinese highway transportation hubs were divided into four levels. The paper concludes that it is effective categorization method of highway transportation hubs combining factors analysis with Kohonen network, Chinese highway transportation hubs are 4 levels hierarchical system.
