中文摘要	运用河西走廊3大内陆河流（疏勒河、黑河和石羊河）1955~2006年河流流量、冰川、地质水文和气象实测资料，系统分析了区域内水资源的分布规律及其循环转化关系等。结果表明，河西走廊水资源主要以冰雪水资源、地表水资源与地下水资源的形式存在，分布于3大相对独立的流域水系中；南部祁连山区发育大小河流共计57条，多年平均出山径流量72.410~8m~3。总体而言，近56a出山径流变化比较稳定；走廊盆地主要由8个大型的构造地貌盆地组成，盆地地下水主要接受出山河水及引灌河水的入渗补给，是地表水资源的重复表现形式，多年平均地下水补给量为42.510~8m3/a;20世纪50~90年代，走廊地区地下水补给量减少了约30%，平均每10a减少近3.5*10~8m~3。受构造地貌的制约，自南部山区至北部盆地，地下水与河水之间经过5个不同地带有规律和重复的转化过程，形成完整统一的山区地下水一地表水一南盆地地下水一地表水一北盆地地下水的水资源循环系统。
英文摘要	The runoff, glacier, hydrological geology and climatological observed data of three inland rivers (Shule River, Hei River and Shiyang River) basins in Hexi corridor from 1955 ~ 2006 were used to analyse systematicaly the law of distribution and its cyclic transformation relations of water resources in these basins. The results indicated that water resources of Hexi Corridor mainly exist with ice-snow, surface and groundwater resources, distributed around the three relatively independent river basins. All together 57 rivers develop in southern Qilian Mountains, and the average annual runoff from the mountain areas totals 72.4 x 10~8m~3. On the whole, the runoff from the mountain areas is very stable in recent 56 years. Hexi corridor is mainly composed of egiht basins in structural landform, and the ground water of these basins mainly receive river-water from mountain areas and the vertical ground water recharge in the area, these are the repeated manifestation of earth’ s surface water resources. The average annual recharge of ground water is 42.5 X 10~8m~3. In the years of 1950s ~ 1990s, the ground water recharge in the area reduces by 30%, about 3.5 x 10~8 m~3 every 10 years. Subject to the structural landform, from southern mountain to northern basin, groundwater and river-water form a complete and unified circulatory system of water resources as "ground water in the mountain surface waterr ground water of southern basin surface water ground water of northren basin" after undergoing regular and repeated conversion process in 5 different zones.
