中文摘要:
      近年来,黄河源区水资源状况发生了较大变化,为探究黄河源区径流变化特征及影响因素,基于1961-2018年共58 a的径流和气象资料,采用Mann-Kendall检验和小波分析等方法对其进行了分析。结果表明:黄河源区径流量整体上呈现出不显著减少趋势,递减速率为-0.63×108 m3/a,夏、秋季减少幅度大,冬、春季减少幅度较小;1990年前后径流量均呈现不显著增加趋势,且1990年后增加趋势明显加速,后者增幅是前者的3.09倍;1990年后,降水量和气温递增高值区高度重合,且降水量是影响径流量变化的最重要因素。说明暖湿化加速和空间迁移过程导致了黄河源区冰川的加速消融,这也是1990年后径流快速增加的主要原因。
英文摘要:
      In recent years, the water resources conditions in the source area of the Yellow River have changed considerably, based on 58 years of runoff and meteorological data from 1961-2018, Mann-Kendall test and wavelet analysis were used to analyze the characteristics and influencing factors of these runoff changes. The results show that the runoff showed a non-significant decreasing trend as a whole by the rate of -0.63×108 m3/a, with a larger decrease in summer and autumn, but a smaller decrease in winter and spring; however, it presented a non-significant increasing trend both before and after 1990, and the increasing trend accelerated significantly after 1990, the latter was 3.09 times of the former. Meanwhile, the increasing high value area of precipitation overlapped with that of temperature after 1990, and precipitation was the most important factor affecting runoff changes. These findings indicate that the accelerated warming and humidification, as well as its spatial migration directly led to the accelerated melting of glaciers, which was also the reason for the rapid increase of runoff after 1990 in the source region of the Yellow River.
