| Abstract: | The north China region is one of the most important agricultural regions in China.Based on winter wheat growth and yield data and daily precipitation data obtained from 56 stations in north China,the level of drought indicators and periodic variation characteristics of the disaster area with different levels of drought are analyzed.Firstly,the correlations between anomaly of winter wheat drought indices and relative meteorological yield are analyzed.Secondly,the distribution map of the degree of correlation... |
| Keywords: | anomaly of winter wheat drought indices relative meteorological yield disaster rate of drought wavelet analysis north China |
