摘　　要：节水会改变灌区原有水循环状态,进而影响水循环伴生的生态与环境过程,节水力度越强、规模越大、范围越广,对生态环境系统的影响也就越大。节水必须保证区域生态稳定。针对我国西北地区水资源紧缺、生态环境脆弱的现状,综合深度节水控水与保护生态环境两方面,提出灌区实施深度节水的生态发展模式,为缓解西北干旱区的缺水形势提供参考。Water conservation will change the original state of the water cycle in the irrigation area,which in turn affects the ecological and environmental processes associated with the water cycle,the stronger the water conservation efforts,the larger the scale,the wider the scope,the greater the impact on the ecological environment system,and water conservation must ensure the regional ecological stability.In view of the shortage of water resources and the fragile ecological environment in northwest China,combining the two aspects of deep water saving and water control and ecological environment protection,puts forward the ecological development model of deep water saving in irrigated areas,which provides a reference for alleviating the water shortage situation in the arid area of Northwest China.
