摘  要：
温度是影响棉花生长的重要因子。选择山西省运城市1971—2010年地面气象观测站的年气温资料,运用线性回归分析法研究运城市棉花生育期气温变化的特点。结果表明,运城市最近40 a,年平均气温逐步上升,呈暖干化趋势,气温变化倾向率为0.30℃/10 a;春、冬季变暖趋势明显,夏季气温有所下降;≥10℃有效积温增长速度为41.3℃/10 a;棉花播种季节温度升高趋势为0.52℃/10 a。气温升高对提高棉花产量有一定的积极意义,但也要注意低温冷害对棉花造成的伤害。

摘  要：
Temperature is one important factor for cotton. With linear regression analysis methods, the air temperature was analyzed in cotton production area in Yuncheng city during cotton growth stages, general changing patterns of temperature in Yuncheng were assessed from the aspects of all surface meteorological stations, on the basis of temperature series(1971-2010)from the stations in the city. The results indicated that, in the past 40 years, the annual temperature series exhibited a significant increase trend(0.30 ℃/10 a)over the city. Trend of warming spring and winter showed obviously, also with a temperature decrease in summer. The effective accumulated temperature increased(41.3 ℃ /10 a). The plantting season temperature increased(0.52 ℃ /10 a). Certainly, rising temperature will have positive meaning for increasing crop yield, but we should also pay attention to the damage caused by chilling injury on cotton.
