| 摘 要： | 在研究河南省小麦锈病发生发展特点的基础上,利用相关分析方法,普查出与锈病关系密切的关键旬降水因子。在对锈病进行小波分析后发现,未来8 a内锈病发生的总体趋势偏重,3 a内锈病发生程度将低于平均水平。同时,对关键旬降水量也利用小波进行了分析。最后,采用多元回归方法建立了河南省锈病发生面积与关键降水单元的关系模型。

| Abstract: | Fully considering the characteristic of Henan wheat rust,using correlation analysis method,the key dekad precipitation factor which is close relationship with rust is found.The wavelet analysis shows the next 8 years rust occurrence will aggravate,and the next 3 years rust occurrence degree will be lower than the average lever.At the same time,the key dekad precipitation has also analyzed by using the wavelet.Finally,the relationship model between rust in area and the key precipitation unit in Henan is established by using the multi-dimensional return method. |
