| 摘 要： | 用新疆阿勒泰地区7个气象站1964～2001年暖季(5～9月)20 cm口径蒸发皿蒸发量资料,运用线性趋势法、相关法分析发现,就整个地区平均而言,暖季蒸发皿蒸发量呈较明显的下降趋势;在区域内富蕴站呈显著上升趋势,吉木乃和布尔津站变化不显著,与全区不同步.完全相关系数法分析表明,整个地区平均而言,低云量、平均风速、气温日较差与蒸发皿蒸发量有显著的相关性,是影响蒸发量的主要因子,但各站有所不同.低云量及气溶胶等污染物的增加导致太阳辐射量减少,而引起气温日较差减少,最终导致蒸发量减少;平均风速减小则主要与全球变暖背景下亚洲冬季风和夏季风减弱导致我国平均风速减小有关.

| Abstract: | Based on 20 cm pan evaporation data of 7 weather stations in warm seaon from 1964 to 2001(May-September) in Xinjiang Aletai area,the feature of evaporation change was analyzed using the linear trend and correlation analysis methods.On average in this area,the pan evaporation in warm season presented remarkable decreasing trend,while it was increasing in Fuyun,and was no obvious change in Jimunai and Buerjing.Analysis on the complete correlation coefficients of climate factors with pan evaporation on regiona... |
