| 摘 要： | 针对四川省作物干旱监测业务服务需求,选择能够充分反映作物不同生育期干旱程度并容易获得的多个因子指标,采用主成分分析法确定各指标的权重,根据工作经验进行细微调整,构建冬小麦干旱综合监测预警指标,并在此基础上建立了四川盆地冬小麦干旱监测预警系统,实现逐日监测预测并输出图形。模型有利于对盆地小麦旱情进行综合判断,检验效果良好,可在业务中逐步完善推广。

| Abstract: | Aiming at the operation and service demands of crop drought in Sichuan Province,multiple factor indices were selected which can reflect crop drought degree at different growth stage adequately and easy to obtain.The Analytic Principal Component method was used to determine the weight of each factor,and the weight could be tiny changed according to work experience.On this basis,the wheat drought monitoring and warning system of Sichuan Basin was established which could be used as drought monitoring day by da... |
