| 摘要：利用库尔勒垦区29团气象站2000-2009年气象资料，分别对垦区近10a稳定通过10℃、15℃、20℃界限温度的初、终日期，持续日数，积温及无霜期变化进行了分析。结果表明：近10a库尔勒垦区各界限温度的初日偏早、终日偏晚；稳定通过各界限温度的持续日数均多与历年；各界限温度积温均呈上升趋势；无霜期日数呈略下降趋势且近10a平均初霜日偏早，终霜日明显偏晚。棉花是喜温喜光作物，在棉花播种期、苗期、蕾期及花铃期对热量资源都有一定的需求，通过对热量资源与相应年份棉花单产的相关分析，得出热量资源丰富的年份棉花单产较高。 |

| Abstract：Make use of the meteorological data during 2000-2009 from 29 corps of korla weather station,the heat index was analyseed for the first day,the last day,the day number of duration,the active cumulative temperature and the frostless season of three boundary temperature(10℃,15℃,20℃) respectively.The results show the first day of boundary temperature has become earlier,while the last day be come later; Stability through three boundary temperature of the day numbers of duration are more than calendar year . Three boundary temperature of the cumulative temperature has increased. The frostless season has been declined slightly and the first-frost period become earlier, the final frost be come later. Cotton is a kind of crop of thermophilic and light-preferring, it has a requirement of heat resources during its sowing time, seeding stage, floral bud emergence as well as blossoming and boll-forming stages. Through correlative analysis of heat resource information and corresponding years' cottons' per unit area yield, the conclusion that cottons' per unit area yield is higher in years that has a richer heat resource can be drawn. |
