摘　　要：本文就宽滩山对河西走廊南侧酒西盆地与北侧花海盆地的水文地质作用开展研究.根据目标区域面积大、水文地质类型复杂的特点,采用卫星遥感数据判读区域构造,划分水文地质单元的基础上进行相应的地球物理勘探工作;通过宏观大尺度遥感影像与沿线地质-地球物理小尺度地球物理证据分析,表明宽滩山对南侧的酒西盆地补给作用较小,对祁连山北侧山前补给形成阻水构造;同时宽滩山对花海盆地形成南侧高地,宽滩山发育的季节性河、泉为花海盆地补给来源之一,但作用较小,形成了花海盆地南侧阻水构造.通过调查认为宽滩山将酒西盆地与花海盆地分为了2个独立的水文地质单元.The hydrogeological effect of Kuantan mountain on Jiuxi Basin in the south and Huahai Basin in the north of Hexi Corridor is studied in this paper.Based on the large area and complex hydrogeological types of the target area,satellite remote sensing data was used to interpret the regional structure,and then the hydrogeological units was done,and corresponding geophysical exploration work was carried out.Through the analysis of macro large-scale remote sensing images and geological geophysical small-scale evidence along the line,it has shown that the Kuantan mountain has little supply to the Jiuxi Basin in the south,and has formed water blocking structures in the piedmont of the northern side of the Qilian mountains.At the same time,Kuantan mountain,where the seasonal rivers and springs developed are the sources of supply water resources for the Huahai Basin but their role is relatively limited,forms a southern highland in the Huahai Basin and a water blocking structure on the southern side of the Huahai Basin.Through the investigation,it has been believed that Kuantan mountain divides the Jiuxi Basin and Huahai Basin into two independent hydrogeological units.
