摘要：利用博格达山北麓6个气象站35年来的降水量及气温记录,对季、年的水热组合状况及其变化进行统计分析,探讨气温、降水在垂直方向上的变化特征。得到的基本结论为:①从变化趋势看,35年来基本以暖湿气候为主,也有暖干和冷湿气候出现;②该区气候垂直变化特征显著,20世纪90年代以来(1991-2006年)与前20年(1971-1990年)相比,平原绿洲区的增温(湿)幅度大于海拔较高的山区,且不论在哪个高度上,冬季增湿幅度均大于夏季;③气温垂直变化率因季节而异,冬季出现明显逆温现象;降水垂直梯度季节差异显著。
This paper analyzes mainly the long-term （1971 -2006） data of seasonal and annual temperature and precipitation observed at 6 meteorological stations in northern piedmont of the Bogda Mountain based on the statistical methods, and discusses the vertical change of temperature and precipitation with altitude. The results are as follows： （ 1 ） Viewing from the change trend, it was dominated by warming-wetting climate with rare warming-drying and cold-wetting climate ; （2） The vertical change of climate was obvious ： both temperature increase and precipitation increase in the plain oases were higher than that in the regions with high altitudes since the 1990s compared with that in previous 20 years （ 1971 - 1990）, and the precipitation increase in winter was higher than that in summer wherever at any altitudes ; （ 3 ） The vertical change rate of temperature was different from different seasons, and there was an obvious temperature inversion in winter. Vertical gradient of precipitation was significantly different from different seasons.
