摘　　要：通过对甘肃冬小麦生物特征的探讨,运用统计学方法分析了气象因子对冬小麦产量的影响,建立了气候产量预测及种植风险决策模式,评估了甘肃省冬小麦种植风险程度,确立了冬小麦生态气候综合区划指标体系,作出生态气候适生种植区划,并提出提高生态气候资源利用途径。Through discusssing phenological characteristic of winter wheat , the influence of meteorological factors during wheat growth period to the output has been analysed by means of statistical methods, the model to forecast the climatic yield of wheat has been given and the degree of risk of planting winter wheat has been estimated, the winter wheat ecoclimate compatibility has been discussed and the index system to delimit ecology climatic region of wheat has been established. The wheat ecoclimatic regions have been delimited according to the index system and the methods to promote the degree of utilizing ecoclimtic resource have also been given.
