摘要: 为了揭示祁连山不同高度带的气候差异性规律,选择了祁连山自然保护区的森林、草原和荒漠建立气象站,气象站分别位于不同的高度带,进行长期定位监测。气象站分人工和自动两种,人工监测从1985年开始,自动监测从2003年开始。基于22 a气象监测数据,利用平均值法、Excel电子图表等方法对监测数据进行深入分析。结果表明,平均气温有逐年升高趋势,降水有逐年下降趋势;年平均气温和年降水量呈负相关关系,年日照时数和年蒸发量呈正相关关系;荒漠、草原和森林带气温变化曲线一次性方程斜率都为正,分别为0.0182、0.0427和0.01167,3个带的年平均气温都是上升的;地温、日照和蒸发均为荒漠>草原>森林。

Abstract: A long-term observation was conducted to analyze the climate variation of different elevation zones in Qilian Mountains. The automatic observation started in 1958, and the manual observation started in 2003. Observation stations are set up in the forest, steppe and desert belts respectively. Analyzing results showed that the mean temperature increased year by year, but the precipitation decreased year after year. The annual mean temperature was negatively correlated with annual precipitation, and the annual sunshine hours was positively correlated with annual evaporation. Linear equations of annual mean temperature in three elevation zones all had positive slope, being 0.0182, 0.0427 and 0.01167 respectively from desert to steppe and to forest belt. The ground temperature, sunshine hours and evaporation fall into variation order of desert>grassland>forest.

Key words: climate, variation, elevation zone, Qilian Mountains
