摘要： 利用1961-2000年的逐月气候资料，分析了松嫩平原农业气候因子的变化特征与趋势。结果表明，在全球变暖的大气候背景下，过去40年中松嫩平原地区年平均气温显著升高，增温速率在0.4℃/10a以上，进入20世纪80年代以后，年平均气温上升趋势更加明显。各个季节及作物生长季平均气温与时间序列的回归趋势均达到显著水平，冬季增温速率最大。年平均最高气温和冬季平均最高气温增加显著。年平均最低气温、四季平均最低气温和作物生长季最低气温增加均较显著，冬季和春季平均最低气温增加速率较大。对降水量的分析结果表明，除1961-1980年作物生长季降水呈明显减少趋势外，年总降水量和各季节降水量变化趋势不明显，在过去40年中并无明显的增加或减少趋势。此项研究结果可以为松嫩平原农作物布局、种植结构调整等农业生产管理决策提供借鉴。

Abstract: Based on monthly climatic data from 1961 to 2000, the changing characteristics and trend of agroclimatic elements in Songnen Plain were studied. Results showed that, under the circumstances of global warming, during the past 40 years, the average annual temperature increased obviously and the warming speed was above 0.4℃/10a. After 1980, the warming trend was more obvious. The average air temperature in every season and in cropping season increased significantly. The average temperature in winter increased with the biggest ratio. The annual and winterly average maximum temperature increased with obvious trend. The annual, seasonal, and cropping average minimum temperature added significantly. Among which, the increasing ratio of average minimum temperature in winter and in spring were larger. For annual rainfall and the rainfall in 4 seasons, there was no obvious trend to increase or to decrease. However, during the period 1961-1980, rainfall in cropping season decreased significantly. The study results could be of interest for crop planning and cropping structure adjustment in Songnen Plain.
