气候变化对东北地区玉米产量的影响

Effects of Climate Change on Yield of Maize in Northeast China

利用对东北三省局地气候特征具有代表性的9站点1961~2006的气象资料和玉米产量资料,采用贝尔产量模式思路的方法研究影响不同区域玉米产量的气候因子。结果表明黑龙江省和吉林省玉米气候产量主要受温度因子的影响,随着气候变暖玉米气候产量逐渐增加;辽宁省玉米气候产量主要受降水和日照时数的影响,不同地区影响效果不同。

Based on the meteorological data and production data of maize of 9 stations in Northeast China from 1961 to 2006,the primary climatic factors influencing maize yield in different region were studied by the method of Baier yields models.The result showed that the yield of maize in Heilongjiang and Jilin Province were mainly affected by temperatures,with air temperature increased,the meteorological yield of maize increased.The meteorological yield of maize in Liaoning Province was mainly affected by precipitation and sunshine duration,and different regions had different effects.
