Abstract: Through detailed analysis on climate change in the period of 1981￣1994 in Hubei Province, it was found that the yearly mean temperature in this province was getting lower gradually which was different from the results of study on the globe and other palces of China. The climate getting warmer in winter and getting cooler in summer was the main features in Hubei Province. There was a demarcation line of air temperature change near 111°E. Air temperature was getting warmer in winter and is getting cooler in summer on the east of the line. Air temperature dropped at all seasons on the west of the line. The yields of wheat and oil rape were affected by the climate change. The effects of climate change were more obvious in east than in west. It was favourable for high yield of wheat in the 1980’s when the precipitation and the rain days were reduced in April and May.
