Using meteorological data of Laiyang during winter wheat growth stage from 1952 to 2007, the characteristics of climatic change and the impact on wheat production were studied. The influence of meteorological factors change on the yield of wheat in Laiyang were analyzed , and the agro-meteorological suggestions and countermeasures , such as the adjustment of sowing period were proposed which could provide references for wheat production of Laiyang to adapt to climate change. The results showed that the temperature is rising during the growth period of winter wheat, and precipitation is dropping at a rate of 2.56 mm per 10 years, sunshine hours is decreasing at a rate of 21.02 hours per 10 years. The climate warming put off the seeding date, shorten the growth season, increased drought degree, and the climatic yields were declined. Climate change was not conducive to wheat growth.%利用莱阳市1952～2007年冬小麦生育期内的气象资料,对该期的气候变化特点以及气候变化对小麦生产的影响进行研究.分析了气象要素变化对莱阳市小麦产量的影响,提出了调整播种期等农业气象建议和措施,为莱阳小麦生产适应气候变化提供依据.结果表明,在小麦生育期间,气温上升,降水量以每10年2.56 mm的幅度下降,日照时数以每10年21.02 h的速率减少;气候变暖使小麦播种期推迟,全生育期缩短,干旱程度加重,气候产量下降,气候变化不利于小麦生长.
