摘要： 为了研究通辽市极端温度对农作物生长的影响，为其粮食稳产高产提供气候依据，利用境内7个测站1959—2010年连续52年逐日温度资料，进行作物生长季（5—9月）平均最高气温、平均最低气温、气温日较差的气候特征分析。结果表明，通辽市平均最高气温和平均最低气温均为上升趋势，日较差为减小趋势，均在0.01显著性水平以上，三要素均符合赫斯特现象，H指数>0.5，分别为0.7946、0.9024和0.9751。未来短时间内平均最高气温和平均最低气温将维持上升趋势，日较差将维持减小趋势。

Abstract: In order to study the Tongliao extreme temperature for the growth of crops, and the influence of the stable grain production for high yield and provide basis for climate, the use of domestic seven station 52 years (1959-2010) daily temperature data of crop growth season (May - September) average highest temperature, average minimum temperature, daily range of temperature the climate characteristics of analysis. The results showed that, the highest temperature and the average Tongliao City average minimum temperatures were rising trend, all at 0.01 significant level above, three elements were in line with Hurst phenomenon, H index which was more than 0.5, were 0.7946, 0.9024 and 0.9751. Future short time average highest temperature and average minimum temperature would keep rising trend, daily range will remain trend of decrease.
