摘要: 利用2006年夏季祁连山七一冰川野外观测资料,计算了2006年七一冰川的冰川融水径流模数,为119.85 L·s-1·km-2,是20世纪70年代七一冰川径流模数的2.23倍;依据径流模数估算出2006年冰川融水径流在黑河4条支流出山径流量中的比重为9.6%,大于1991年8.2%的统计值。黑河流域东部河流出山口径流量中冰川融水所占比重变化不大,西部河流冰川融水补给比重显著增大,强烈反映了在全球气候变暖背景下,祁连山冰川对气候变化过程的响应。

Abstract:

Surface ablation, meteorological factors and hydrological regimes of Qiyi Glacier had been monitored in 2006, by which the glacial meltwater runoff modulus in 2006 was calculated by 119.85 L·s-1·km-2, 2.23 times as that in the 1970s. The proportion of glacial meltwater runoff in the four typical river basins of the Heihe River water system to the mountainous runoff in 2006 was estimated to 9.6%, larger than the value of 8.2% in 1991. The change of proportion suggested sensitive response of Qilian Mountains Glacier to global warming.

Key words: glacial meltwater runoff, runoff modulus, mountainous runoff, Heihe river basin
