Effects of Climate Change on Yield of Maize in Northeast China

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.
