摘要:
为探讨流域极端气候事件的演变规律,基于疏勒河流域瓜州站、玉门站和敦煌站1951—2018年月气温极值数据,采用线性倾向、滑动平均等方法分析了疏勒河流域气温年、季极值变化特征、突变特征以及周期特征。结果表明:(1)年极值气温变化均呈上升趋势,年最高和最低气温分别以0.06℃/10 a和0.27℃/10 a的速率上升,但年最低气温上升趋势较年最高气温显著;(2)季最高气温变化均呈上升趋势,倾向率排序表现为冬季(0.36℃/10 a)>春季(0.23℃/10 a)>夏季(0.07℃/10 a)>秋季(0.01℃/10 a),且各季呈现不同波动变化趋势;(3)季最低气温均呈现上升变暖趋势,倾向率排序表现为秋季(0.53℃/10 a)>春季(0.39℃/10 a)>冬季(0.24℃/10 a)>夏季(0.19℃/10 a),且各季呈现不同的波动变化趋势;(4)流域年最高气温和年最低气温突变时间分别为2011年和1961年。(5)年最高气温和年最低气温的第一主周期均为58 a。总的来说,疏勒河流域的气温在未来几年还会持续升高。研究成果对于全面认识疏勒河流域气候变化特征、合理开发利用水资源具有一定的现实意义。
Abstract:
In order to explore the evolution pattern of extreme climatic events in the basin, based on the monthly temperature extreme data at Guazhou Station, Yumen Station and Dunhuang Station in the Shule River Basin from 1951 to 2018, the linear trend and moving average methods were used to analyze the characteristics of annual and seasonal extreme temperature changes, sudden changes and periodic characteristics in the Shule River Basin. The results show that:(1)the annual changes of extreme temperature showed an upward trend; the annual maximum and minimum temperatures increased at a rate of 0.06℃/decade and 0.27℃/decade, respectively, but the annual minimum temperature increase trend was more significant than the annual maximum temperature;(2)seasonal changes of maximum temperature showed an upward trend, the tendency rate was in order: winter(0.36℃/decade)>spring(0.23℃/decade)>summer(0.07℃/decade)>autumn(0.01℃decade), and different seasons showed different fluctuating trends;(3)seasonal changes of minimum temperatures all showed a rising and warming trend, and the order of trend rate were autumn(0.53℃/decade>spring(0.39℃/decade)>winter(0.24℃/decade)> summer(0.19℃/decade), and different seasons presented different fluctuating trends;(4)the mutation times of the annual maximum temperature and the annual minimum temperature in the basin occurred in 2011 and 1961, respectively;(5)the first major cycle of the annual maximum temperature and the annual minimum temperature were both 58 years. On the whole, the temperature in the Shule River Basin will continue to rise in the next few years. These research results have certain practical significance for the comprehensive understanding of the characteristics of climate change and the rational development and utilization of water resources in the Shule River Basin.
