摘　　要：粮食安全不仅取决于粮食生产的量和自给率,还取决于可获性,包括"买得起"和"买得到"。当前中国粮食总量安全,但粮食生产的区域结构性矛盾突出,粮食生产日渐向优势区域集中,主销区的粮食消费日益依赖于主产区的粮食调运,粮食运达的及时性对于粮食安全愈发重要。粮食调运必然面临长距离运输问题,这其中尤以在粮食运输网络中起枢纽作用的关键节点的平稳有序运行最为关键。当前实现粮食调运的运输方式主要依靠铁路、水路以及铁水联运,但是这一运输网络存在运力不足、物流方式落后、基础设施建设不足等风险因素,与粮食运输量的增长速度以及运输的顺畅性、及时性要求不相匹配,因此亟待通过加快铁路、水路基础设施建设、推动粮食物流方式变革和健全粮食物流应急响应机制等措施,保障粮食的稳定供给和粮食安全。Food security depends not only on the quantity and self-sufficiency of food production, but also on its availability, including “affordable” and “available”. At present, China’s total grain output is secure, but the regional structural contradiction of grain production is prominent. Grain production is increasingly concentrated in advantageous regions, and the grain consumption in main marketing areas is increasingly dependent on the grain transportation from main production areas. The transportation of grain is bound to face the problem of long-distance transportation especially the stable operation of the key nodes in the grain transportation network. There are risk factors in railway transportation network and water transportation network such as insufficient transport capacity, backward logistics mode and inadequate infrastructure construction. Therefore, it is urgent to accelerate the construction of railway and waterway infrastructure, promote the reform of grain logistics mode and improve the emergency response mechanism of grain logistics so as to guarantee the stable supply of grain and food security.
