摘　　要：依据西北各省 (自治区 )的有关资料 ,对西北内陆河流域的水资源特点进行了综合分析 ,提出了西北内陆河流域水资源的四大特点 :①内陆河流域径流主要形成于山区 ,散失于山前平原盆地 ,径流的补给源主要是降水、冰雪与地下水 ;②冰雪资源对内陆河地表水资源有较大的调节作用 ;③降水、地表水与地下水转化关系特征明显 ;④内陆河区水平衡状态 。Water resources is considered as a key of the development in Northwest China, so its characteristic must be thought enough and accurately The water resource data in Northwest China is analyzed, which indicate that: (1) the runoff of endorheic drainage is mainly formed in mountain regions, dissipated at basin or plain front of mountain, and supplied by the rainfall, snowfall, glacier and groundwater; (2) Glacier and snowfall play an important part in adjustment of surface water; (3)transformation relationship between rainfall, surface water and groundwater is notable,and (4) The water resources balance of endorheic drainage is easily influenced by the human actions
