【摘要】 本文介绍了灰色系统理论GM建模机理及方法,并以广西忻城县蔗区1991/92～1995/96榨季的甘蔗单产数据,建立了甘蔗单产GM(1,1)预测模型,统计结果表明,关联度r=0.7167>0.6,说明灰色系统理论的GM(1,1)模型应用于甘蔗单产的预测,模型精度高、方法简便、结果可信,与人工神经网络等其他方法相比更为准确可靠,不失为一理想的预测方法。更多还原

【Abstract】 The GM of gray system was introdu ced in this paper the data of sugarcane yield which obtained from 1991/92～1995/96 campaign of Xincheng county Guangxi the stat istical results shown that r=0.7167>0.6the GM1,1 of gray system can apply to predict the yield of sugarcane the models have high degree of accuracy the method is feasi ble and the operation i s convenient.更多还原
