| 摘 要： | 目的]研究近47年环青海湖地区气候变化特征。方法]利用1961~2007年环湖地区5个气象观测站的气温、降水和日照等气候要素资料,分析各气象要素的年、季、年代变化。结果]近47年来,环湖地区气温上升趋势明显,其中年平均气温以≥0.30℃/10 a的倾向率上升,年平均最低气温比年平均最高气温上升显著;年平均降水量呈减少趋势,其气候倾向率为-3.67 mm/10 a,春、秋季降水量的减少趋势明显,而夏、冬季呈增加趋势,但不明显;年日照时数也呈减少趋势,其气候倾向率为-1.79 h/10 a,夏季日照时数的减少趋势最明显,冬季次之,春、秋季节增加不明显。结论]该研究为环湖地区气象灾害的有效防御提供了理论参考。
