Based on the fact that the ratio of actual evapotranspiration to potential evapotranspiration depends on the availability of soil moiture and crop growth stages, Crop Water Stress Index ( CWSI ) is submitted to express the crop drought. The CWSI by ten days interval during 11(1980-1991) winter wheat growth years of 60 stations in Huang Huai Hai Plain were calculated in this paper. Then we analyzed the characteristics of CWSI in time and space scale. And the CWSI on the conditions of rain feed and that of irrigation are compared. By contrast of the CWSI and soil moisture index, the CWSI is more sensitive to the deficiency of crop water. Some conclusions are: (1) According to the result of PCA (principal component analysis), the plain is divided into three parts, which are different in the CWSI change process from each other. The southern plain shows drought in March, and the northern plain in the first ten days of February, the before the first ten days of January. (2) Under rain feed the CWSI of the winter wheat in the plain keeps rising from the middle ten days of October to the last ten days of May, while the irrigation can mitigate the drought. (3) In the year with less precipitation the CWSI in the plain is larger and the time of CWSI less than 0.5 is earlier.
