摘要
全球气候变暖正改变着全球水汽,进而深刻影响人类的生存与发展。祁连山是中国西部重要的生态安全屏障和生物多样性保护区域,也是地质灾害的多发区。因此,为了明确祁连山地区气温的时空变化特征,针对祁连山及其周边地区21个气象站点的1960—2019年的气温数据,利用Anusplin气温插值法对祁连山区域的气温进行插值,并借助滑动平均方法、一元线性回归分析、累计距平法等对祁连山地区的气温变化进行详细分析。结果表明:祁连山地区年及四季平均气温呈波动式变化,但总体变暖趋势明显,年均气温倾向率为0.319℃/a;各季节气温变化差异明显,其中冬季气温转暖较早,且升温趋势高于其他季节,升温贡献率最大;气温增温幅度自东南向西北呈逐渐增加的趋势。研究结果可为祁连山地区的生态保护和地质灾害的防治提供一定的理论支撑。
Global warming is changing the global water vapor cycle,thus profoundly affecting human survival and development.Qilian Mountain is an important ecological safety barrier and biodiversity protection area in western China.Therefore,in order to clarify the characteristics of spatial-temporal change in the Qilian Mountains,the Anusplin interpolation method was used to interpolate the temperature data of 21 meteorological stations in the Qilian Mountains and its surrounding areas from 1960 to 2019.With the help of the moving average method,linear regression analysis,accumulated anomaly method and so on,the temperature change in Qilian Mountain area was analyzed in detail.The results show that the annual and seasonal mean temperature in the Qilian Mountains fluctuate,but the overall warming trend is obvious,and the average annual temperature trend rate is 0.319℃/a.There are significant differences in temperature variation among different seasons,and the warming in winter is earlier and the warming trend is higher than that in other seasons,and the contribution rate of warming was the largest.The increased range of temperature increases gradually from southeast to northwest.The research results can provide theoretical support for ecological protection and geological disaster prevention in Qilian Mountain area.
