| 摘 要： | 为研究全球变化背景下中亚河流源区气候水文变化,基于中亚跨境河流瓦赫什河上游源区1955—2017年气象水文数据,分析了流域内气候水文要素演变特征及流量变化主要控制因子。结果表明:瓦赫什河上游源区近1955—2017年气候呈现暖湿化趋势;瓦赫什河上游源区气温在1994年发生突变现象,降水在2007年与2012年发生突变现象,流量则在2003年发生突变现象;小波分析显示瓦赫什河上游流域气温、降水、流量的第一主周期分别为28 a、20 a、28 a,周期性振荡明显;瓦赫什河上游源区在气候水文要素关联上,气温与流量变化相较于降水紧密,但受全球升温停滞影响,温度对于流量作用并没有持续增强。

| Abstract: | In order to study the climatic and hydrological changes in the source area of Central Asian rivers under the background of global climate changes, the evolution characteristics of climatic and hydrological elements and the main controlling factors of discharge variation in the basin were analyzed based on the meteorological and hydrological datas of the upper source area of the Vakhsh River from 1955 to 2017. The results show that the warming-wetting trend occurred in the upper source area of the Vakhsh River from 1955 to 2017. Abrupt changes of temperature, precipitation and discharge in the upper source area of the Vakhsh River occurred at 1994, 2007 and 2012 as well as 2003, respectively. Wavelet analysis shows that the first main cycles of temperature, precipitation and discharge in the upper Vakhsh River basin are 28 a, 20 a and 28 a, respectively with obvious periodic oscillations. With regard to the correlation of climate and hydrological elements in the upper source area of the Vakhsh River, the correlation of temperature and discharge variation was closer than precipitation. However, due to global warming hiatus, the influence of temperature on discharge did not continue to enhance. |
