摘　　要：运用统计学方法，对1960-2008年辽宁东部产粮区5个气象站的气温、降水量及积温、日照、冻土、无霜期等资料进行分析。结果表明，近49年辽宁东部产粮区气候变化特点为气温和无霜期呈上升趋势，降水、日照和冻土深度呈下降趋势。积温初日提前，终日延后；初霜日延后，终霜日提前。The air temperature, precipitation, accumulative temperature, sunshine duration, frozen soil and frost-free season data in 5 weather stations in grain production area of the eastern Liaoning from 1960 to 2008 were analyzed by statistic method. The results indicated that air temperature and frost-free season showed an increasing trend, while precipitation, sunshine duration and frozen soil depth decreased during recent 49 years. The first accumulated temperature date was ahead and the last day was delayed. The first frost date was delayed and the last frost date was ahead.
