In order to study the effect of climate change on wheat growth season and effective accumulated temperature of Chaoyang, the rational response to climate change, to provide the basis for the impact of regional climate change on agricultural production and agricultural disaster prevention and mitigation system construction and improvement. Use of Chaoyang and Jianping from March to July from 1961 to 2011, the daily average temperature data, through the use of climate statistical analysis method, analyzes the Jixiaomai effective accumulated temperature change rule and characteristics of growth arid region of Chaoyang. The results showed that: Jianping and Chaoyang effective accumulated temperature climate mean showed increasing trend, Chaoyang spring, summer and annual effective accumulated temperature was higher than the mean climate of Jianping, increase rate was high in Jianping; the worst heat condition was in 1970 to1979, and the best heat condition was near 2001; Chaoyang and Jianping summer and annual effective accumulated temperature warming trend was basically consistent, point mutation was in 1996 to1997; 1980 to1989 in Jianping become warming, rising from 2000 to 2009 warming, warming faster than Jianping; annual effective temperature increased Chaoyang more apparent than in Jianping, the summer temperature increasing tendency in Jianping than in Chaoyang significantly.
