摘要
运用统计诊断方法分析了齐齐哈尔地区近 4 0年平均气温的年、季变化特征。结果表明 ,齐齐哈尔地区的年平均气温呈上升趋势 ,上升率为每 10年 0 4 4℃ ;齐齐哈尔的增暖幅度远远大于我国的气温增暖幅度 ;四季气温增暖幅度在不同年代差异很大。通过分析齐齐哈尔地区气温变化规律 ,为短期气候预测和农业生产提供了一定的理论依据。
Annual, winter, spring, summer and autumn air temperatures changes over Qiqihar during the last 40 years were analyzed by the statistical diagnosis method. The results show that the annual mean temperature over Qiqihar had an increasing trend and the increase rate was 0 44 ℃ per 10 years, far more higher than that over China. The warming argument was very different for four seasons. The regularities of temperature variations in Qiqihar were analyzed and it provides some certain theoretical bases for short-term climate prediction and agricultural production.
