| 摘 要： | 本文用拉朗日插值法推算江苏省淮北地区冬小麦在无农业气象灾害条件下从1960－2000年41年的期望产量，并用用S软件建立气象灾害对冬小麦产量影响的逐步回归模型，分析了各类农业气象灾害对产量的影响。对指导淮北地区有针对性地防御农业气象灾害，降低其对冬小麦产量的 影响有重要的实际意义。

| Abstract: | The expected yield of winter wheat without agrometeorological disasters in the past 41 years from 1996 to 2000 in Huibei district of Jiangsu province is calculated with the method of Lagrange interpolation A stepwise regression model of influence of agrometeorological disasters on winter wheat is made by use of SAS The influence of different agrometeorological disasters on yield of winter wheat is analyzed This research is of guiding significance to the prevention of agrometeorological disasters and mitigation of their influence on yield of winter wheat |
