我国是世界上人口最多的国家,是粮食产量最大的国家,也是世界粮食贸易中的重要一员。自新中国成立以来,我国粮食产量及生产能力增长较快,虽然在1959~1961年和2000~2003年间粮食产量出现了较大幅度的下降,但整体上仍呈上升趋势。长远来看,粮食生产受资源、气候、技术、市场等因素的制约,并受种粮比较效益影响,产量大幅度增长的难度较大。当前影响我国粮食生产的主要因素是粮食播种面积和单产水平。由于人口增长、工业化和城镇化进程加快等,我国粮食总播种面积呈下降趋势,但随着科技进步加快和农业投入加大等因素的影响,我国粮食作物单产水平呈不断上升的态势。

China has the largest population in the world;it is the largest country of grain yield;and it is an important member of the world trade.Since the founding of new China,total yield and productivity grew rapidly.Although during the period 1959-1961 and 2000-2003,grain production substantially dropped,the general trend of grain yield was upward.In the long run,because grain production will be subject to the restriction of resource,climate,technology and market and it will also be influenced by the comparable benefit of grain growing,it is more difficult for us to substantially increase the grain yield.The main factors influencing grain production are the main grain sowing area and the yield per unit area.Due to the acceleration of population growth,industrialization and urbanization,the total sowing area in China shows a downward trend;but with the help of the progress of science and technology,the increasing agricultural investment and other factors,China＇s grain yield per unit area is rising.
