摘　　要：文中以运输成本、中转成本、环境成本、拥堵成本总和最小构建港口-腹地集疏运网络货流分配模型,并以福建省沿海港口集疏运网络为例进行实例分析.结果表明:考虑了拥堵与环境因素的货流分配方案能使网络的综合成本降低34.3%.当部分集装箱的运输方式由公路转为铁路时,拥堵情况有所改善,碳排放量也大幅减少.Taking the sum of transportation cost, transit cost, environmental cost and congestion cost as the minimum, the cargo flow distribution model of port-hinterland collection and distribution network was constructed, and the coastal port collection and distribution network in Fujian Province was taken as an example for analysis. The results show that the logistics distribution scheme considering congestion and environmental factors can reduce the comprehensive cost of the network by 34.3%. And when the transportation mode of some containers is changed from highway to railway, the congestion situation is improved and the carbon emissions are greatly reduced.
