本文根据联合国粮农组织(FAO)和国际应用系统分析研究所(IIASA)基于中国1961年以来的统计资料共同开发的AEZ模型,运用GIS平台计算了中国41个农作制亚区6大主要作物(水稻、小麦、玉米、马铃薯、油菜、大豆)的单产潜力.指出以上作物单产最高潜力分布为:水稻在江淮江汉平原,小麦在秦巴山区,玉米在黄淮平原南阳盆地,马铃薯在秦巴山区,油菜在秦巴山区,大豆在鲁西平原鲁中丘陵.研究结果表明:我国以上主要作物的最高单产潜力是目前全国平均单产的1.2-2.9倍.这对指导我国农作物高产育种及栽培具有重要参考意义.
Based on the AEZ model jointly developed by FAO and IIASA based on the statistical data of China since 1961, this paper calculated six major crops in 41 sub-regions of China with 41 agricultural systems (GIS) Rice, wheat, corn, potato, rapeseed and soybean) .It is pointed out that the highest potential yield of the above crop yields is as follows: paddy in the Hanjiang Plain, wheat in the Qinba Mountains, corn in the Huangyang-Huaihe Plain in the Nanyang Basin and potatoes in the Qinba Mountains , Rapeseed in Qinba mountain area and soybean in Luzhong hills in the Luxi plain.The results showed that the highest yield potential of above major crops in our country is 1.2-2.9 times of the average yield of the whole country at present.This is important to guide the high yield breeding and cultivation of crops in our country D.
