摘 要: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1961~1997年的统计资料(经多方校正)共同开发的AEZ模型,运用GIS平台研究了中国41个农作制亚区的大豆生产潜力,以及单产和总产最高潜力分布区域。研究结果表明:我国大豆的最高单产潜力大约是目前产量的2~3倍。单产潜力主要分布在鲁西平原鲁中丘陵、黄淮平原南阳盆地及汾渭谷地,总产潜力主要分布在三江平原、黄淮平原南阳盆地及松辽平原。In this paper, soybean yield potentials in 41 Chinese farming system sub - zones were calculated on the bases of AEZ model that was developed by FAO and IIASA according to checked statistical data from 1961 to 1997 in China. The distribution of maximum potentials for soybean yield and output was pointed out on Chinese GIS map. The yield potential mainly distributed over some areas in Shandong, Henan and Shanxi, while the output potential mainly distributed over some areas in Heilongjiang, Henan and Jilin. The results showed that maximum yield potential of soybean could be two to three times of its present level.
