利用内蒙古通辽市库伦旗气象站1961-2014年54年的逐月日照时数资料,运用简单的平均值、一元线性回归、曼-肯德尔(Mann-Kendall)等气候趋势分析方法,比较其变化特征,分析日照时数的历史演变,年际、季节际、月际的变化特点。结果表明:日照时数呈现减少趋势,气候倾向率每10年为-46.525 h;日照时数的季节变化表现为冬季呈现缓慢增多的发展趋势,春季、夏季、秋季呈现下降减少趋势;雨季对日照时数影响较大。
利用內矇古通遼市庫倫旂氣象站1961-2014年54年的逐月日照時數資料,運用簡單的平均值、一元線性迴歸、曼-肯德爾(Mann-Kendall)等氣候趨勢分析方法,比較其變化特徵,分析日照時數的歷史縯變,年際、季節際、月際的變化特點。結果錶明:日照時數呈現減少趨勢,氣候傾嚮率每10年為-46.525 h;日照時數的季節變化錶現為鼕季呈現緩慢增多的髮展趨勢,春季、夏季、鞦季呈現下降減少趨勢;雨季對日照時數影響較大。

By analyzing the monthly sunshine duration of Kulun in Tongliao Inner Mongolia during 1961 and 2014, we compared with their variation characteristic and analyzed the historical evolution of sunshine duration and the interannual and inter-season and inter-monthly variation characteristics using simply mean value, monadic linear regression and Mann-Kendall methods. The results showed that the sunshine duration showed a trend of decrease and the climate tendency rate was -46.525h/10a. The performance of seasonal change of sunshine duration in winter presented the increasing trend slowly but the decreasing trend in spring, summer, autumn. The rainy season had a greater impact on sunshine duration.
