运用地球物探、盆地地质演化、环境同位素示踪与水化学分析、河床渗透试验和地下水流场分析等研究方法 ,综合研究了我国西北干旱区第二大内陆河———黑河下游盆地河水与地下水的转化途径、方式及转化量 ,发现在哨马营至古日乃存在地堑式断层 ,断层带为黑河古河道 .通过河水位与地下水位的关系、河床渗透试验 ,估算出黑河鼎新段河水渗漏量约为 1.76 4×10 8m3/a .黑河鼎新段为古日乃盆地地下水的补给区 ,地下水大多通过古河道进入古日乃盆地 ,保证古日乃绿洲的生存 .为黑河流域综合整治提供了科学依据 .
Using the methods of geophysical prospecting, basin geological evolution, environmental isotope tracing and water chemistry analysis, riverbed infiltration test and groundwater flow field analysis, the paper studies the relationship between river water and the second largest inland river in the arid region of northwestern China It is found that there is a graben fault between the Zhimaying and the ancient days and the fault belt is the Heihe ancient river course.Through the relationship between the river water level and the groundwater level and the riverbed infiltration test, The amount of water seepage is about 1.76 4 × 10 8m3 / a. The Dingxin section of Heihe is a recharge area for the ancient Dayai basin groundwater, and most of the groundwater enters the ancient Dayai Basin through the ancient river course to ensure the ancient day is the survival of the oasis. Remediation provides a scientific basis.
