摘　　要：黄河流域所属的诸省区均为粮食主产区和粮食平衡区,沿黄省区粮食生产事关流域乃至全国的粮食安全。从国家对黄河流域粮食安全定位出发,分别分析了现状和人口高峰时期流域粮食生产情况,研究了粮食安全存在的问题及解决粮食缺口的对策,提出了保障流域粮食安全必须立足流域自身解决的结论。从气候条件、水土资源条件等多个方面分析了黄河流域后备耕地资源潜力,并利用遥感、GIS解疑与现状典型调查等技术方法,研究确定了不同高程条件下可新增耕地规模,为黄河流域未来一定时期土地资源开发和保障流域粮食安全提供了技术依据。The regions of the provinces belong to Yellow River basin are the main food-producing areas and food-balance areas,of which the food production matters to food safety of Yellow River basin and even of China.Based on food safety of Yellow River basin targeted by China,this paper analyses food production situation at present and in the period of population peak,respectively,and studies food-safety problems and the strategy to solve the food gap.Thus,the conclusion that to ensure food safety of Yellow River basin must stand on the way solved by the basin itself is proposed in the paper.Furthermore,this paper analyses the potential of uncultivated arable land resources of Yellow River basin from the multiple aspects including climate conditions,water-land resources conditions and so on,and the remote sensing,GIS disambiguation and current-typical investigation are employed to determine the respective size of additional arable lands available under the conditions of different height,thereby providing the technical foundation for land resources development and food-safety assurance of Yellow River basin in the future.
