摘要： 为了揭示宿州地区气候变化规律，科学利用农业气候资源，促进冬小麦稳产增产。利用1954—2008年的气候资料和冬小麦单产资料，分析了宿州地区气候变化特征以及对冬小麦产量的影响。结果表明：宿州地区年平均温度呈波动上升趋势，其变化倾向率为0.36℃/10年，气温突变时间点为1994年，并且大于10℃积温平均以94.7℃?d/10年的速度增加；平均年降水量为880.5 mm；日照时数总体呈波动下降趋势，年日照时数的倾向率为-52 h/10年；冬小麦气候产量呈现呈“w”型，1960—1969产量较低，而2000年以后气候产量相对较高，气候产量最低的年份为1998年，并且1998年以后，气象产量均为正值。

Abstract: In order to reveal the law of climate change in Suzhou, use scientifically the agro-climatic resources , and promote the high and stable yield of winter wheat, based on yield of winter wheat and climate date from 1954 to 2008, climate change and the impacts on yield of winter wheat were analyzed in Suzhou. The results showed that, the average annual temperature had fluctuantly increased, the change rate was 0.36℃ per 10 years, the time of temperature change suddenly was 1994, the accumulative temperature above 10℃ increased by 94.7℃ per 10 years. The average annual precipitation was 880.5 mm. The duration of sunshine had fluctuantly decreased, the change rate was -52 per 10 years. The climate yield of winter wheat was “w” curve, it was lower from 1960 to 1969 and higher in later 2000, the lowest year was 1998, and the climate yield was positive later 1998.
