• On basis of the research result of stripe rust for 16 years since 1999, the epidemic characteristics and trend of stripe rust in the city were determined. Namely, the earlier the initial stage appeared, the heavier the disease would be. In farmlands, there are one to three epidemic peaks, and the infection area of the first peak plays the key role on the epidemic area of that year. In addition, the accumulated areas of late January was in significantly positive correlation with annually total area, with a correlation coefficient of 0.769. In recent 16 years, the frequency of severe stripe rust was as high as 81.25% which was 50% higher than that before 1995. The slight stripe rust became just in 2013, with a frequency of 6.3%, which indicated that the city has become a region hit by severe stripe rust. Big fluctuation of temperatures in warm winter and spring, foggy and dew days slants much would be the external reason.
