摘　　要：根据甘肃省近几十年的水文、气象资料,分析了甘肃省干旱多发的成因。结果表明,甘肃省干旱的发生不仅与其处于青藏高原东北部受季风影响有关,而且与该省的地形地貌、气象、降水、地表、地下和冰川水资源分布及水质,还有省内河川径流有关,尤其与人类社会经济活动有直接关系。According to the hydrological and meteorological data during the recent decades,the causes of drought in Gansu Province were analyzed.The results indicated that the causes of drought not only arose in part from the monsoon due to its location in northeastern Tibetan Plateau,but also related to the province＇s topography,meteorology,rainfall,and surface,underground and glacier water distribution,as well as river runoff,in particular related to the human socio-economic activities directly.
