| 摘 要： | 通过计算得出了陕西关中地区年、四季实际蒸散发量和气候因子的空间分布特征及实际蒸散发量与其影响因素的偏相关系数,分析了实际蒸散发量和气候因子的突变和周期性质。结果表明,关中地区年和四季实际蒸散发量的空间分布是一致的,而与其影响因素的偏相关系数却不同。关中地区年实际蒸散发量在1974年发生了突变性的减小且存在9a的振荡周期。

| Abstract: | The space distributions of the annual and seasonal areal evapotranspiration and the climate factors have been analyzed in this article.The partial correlations between the areal evapotranspiration and the climate factors have been calculated.The jump and anomaly and the cycle characteristics of the areal evapotranspiration and the climate factors have been analyzed.The results show that： the spatial distributions of the annual and seasonal areal evapotranspiration are similar while the partial correlations between the areal evapotranspiration and the climate factors are different.The areal evapotranspiration in the Guanzhong region reduced jumpily when it was in 1974,and it exists nine years＇ cycle. |
