摘要
粮食安全是国家安全的重要组成部分。随着经济的发展,我国粮食产销格局由"南粮北运"演变为"北粮南运"。在此背景下,本文从粮食单产、人均粮食产量和粮食贡献度角度分析了我国粮食生产的空间差异。尽管我国粮食安全的总体特征呈现出供需基本平衡、丰年有余的态势,粮食生产的持续发展还面临着诸多问题。在单产跃进的基础上实现总产提升,在产销区的衔接与平衡、"断线"品种的协调与调配的基础上,完善粮食储备,构建预警体系是我国粮食安全问题的重大战略举措。
Grain security forms an important part of state security. Along with economic development, the direction of food transportation changed transporting cereals to north from south into south from north in China. Taking the point of view of per unit area yield of grain, per - capita share of grain and contribution degree of grain as breakthrough point, this paper researched the spatial differences of grain production. Through general characteristics of grain security shows overall balance with surpluses during good years, the sustainable development of grain production faces many problems. Therefore, on the basis of making per unit area yield leap, the promotion of grain total output should be realized. Based on join and balance between production areas and marketing areas, and the coordination and coordination of grain in short supply, the perfection of grain reserves and construction of forewarning system are the significant strategy moves of grain security in China.
