摘要
利用天山北坡中段呼图壁河流域石门水文站1956—2011年径流量数据,以及2013年9月—2014年10月逐月呼图壁河地表径流和地下水的δD和δ18O数据,研究了呼图壁河流域地表径流和地下水位变化,并结合同位素和水化学方法探讨了地表径流和地下水之间的转化关系。结果表明,近55 a呼图壁河流域出山口径流量有明显增加趋势,在20世纪90年代之后增加了13.36%,而地下水位呈持续下降趋势。流域地表水与地下水水化学特征差异显著,地表径流受岩石风化作用影响,而地下水受蒸发—结晶沉降作用控制。该流域地表水与地下水出现了两次转化关系,上游地区地下水对地表径流的补给占到18.45%,而中下游区域地下水的补给占到92.31%。
Based on the annual runoff data over the Hutubi River basin during 1956-2011,and the stable isotope(δD andδ18O)of river water and groundwater from 2013 to 2014,we investigated the surface runoff variation,and discussed the transformation relationship between the river water and groundwater in the Hutubi River basin.We found that the annual runoff showed a significant rising trend(P<0.001)and step change points in 1990s(P<0.05).Runoff has increased by 13.36%after 1990s.The underground water levels steadily decreased in this basin.The chemical characteristics had significant difference between the river water and groundwater,and the river water is controlled by rock weathering,but the groundwater is controlled by evaporation-crystallization sedimentation.The water had occurred the twice transformations,the groundwater recharge accounted for 18.45%in the upstream of river water,and accounted for 92.31%in the middle and lower stream.
