Short summary
In order to organize water for drought resistance reasonably, We chose eight typical irrigation districts in Yellow River basin as research area. The results showed that the reconnaissance drought index (RDI) can be applied to evaluate the meteorological drought in the typical irrigation districts. There is significant correlation between the irrigation water demand and RDI, and the grey correlation degree and correlation coefficient increased with increasing crops available effective rainfall.
