基于AEZ模型的我国马铃薯产量潜力的农作制区划分析

Analyses of Potato Yield Potential by Chinese Farming System Zoning Based on AEZ Model

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平台计算了中国41个农作制亚区的马铃薯生产潜力,并指出了单产最高潜力分布区域。研究结果表明:我国马铃薯的最高产量潜力大约将是目前产量的2～3倍。这对我国马铃薯高产育种及栽培具有重要参考意义。

In this paper, potato yield potentials by 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 potato yield potential on Chinese GIS map was pointed out. The results showed that maximum yield potential of potato will be about two to three times of its present level, which is valuable to potato high yield breeding and cultivation.
