BAI Ming-qi et al (School of Atmospheric Science,Lanzhou University,Lanzhou,Gansu 730000)  
[Objective] The study aimed to provide the basis for the adaptation of agriculture production to temperature change in Heilongjiang Province.[Method] With daily meteorological data in 1961-2003 in Heilongjiang Province,the influence of temperature changing trend on rice yield changing trend was analyzed by using the world food study model WOFOST and mathematical method for analyzing the climate changing trend.[Result] In rice growing area of middle, eastern and northern of Heilongjiang Province,the effect of temperature increasing trend on rice simulated yield increasing trend was the most significant,in Qiqihar,Daqing,western of Harbin with abundant heat resource in western of Songnei plain and the local warm and cool region in northern of Yili area,while the effect of temperature increasing trend on simulated yield increasing trend was the following.Only in local area with abundant heat resource in borderland of 3 counties of Tailai,Taikang and Zhaoyuan in southwest of Songnei plain,the effect showed the small decreasing trend.[Conclusion] The average value of percentage of change trend of rice simulated yield in 10a in Heilongjiang Province was 6.37%,and temperature rising was the main reason of climate change.
