摘　　要：干旱区生态用水的水质与水量具有较大的变幅范围 ,用水的方式比较灵活 ,水分的供给状况影响生物的生产力。生态用水受制于SPAC中水分循环与转化的效率 ,并与植被特征、土壤理化性状、地形特点、水资源利用水平具有密切的相关性。生态用水量的估算有许多参数与模型需要率定 ;干旱区内陆河流域生态用水观念的确立 ,对于完善生态水文学的学科体系 ,指导水资源的科学管理和生态实践 。The quality and quantity of water for ecological use have a large variable range in arid zone. Meanwhile, water use style is flexible and has diversified forms. Water supply has influence on organism productivity. Water for ecological use is under the control of water circulation and transfer efficiency of GSPAC, which has close relation with vegetation characteristics, soil physical and chemical features, and terrain condition as well as water use level. Estimation of water quality for ecological use is based on some parameters and models. The ideas of water for ecological use have significances for improving eco-hydrology and water resource management , ecological practice and sustainable development of ecological industry in continental river basin in arid zone.
