摘　　要：为保障大兴区水资源的可持续利用,研究了大兴区GEF真实节水示范区的节水方法并预测未来节水效果。以真实节水理念为指导,基于遥感ET和目标ET,制定了机井取水量定额和取水量消减计划。结果表明,示范区现状机井取水量为119.2万m3,机井取水定额累计为107.0万m3,消减的机井取水量为12.1万m3,占现状取水量的10.2%;根据消减计划,到第五年基本实现消减任务。该研究对于提高水资源利用效率,开展区域农业节水管理,提供了一种有效的方法和示范推广作用。To guarantee the sustainable using of water resources in Daxing district,this paper studies the water-saving methods for the Daxing GEF real water-saving demonstration area and predicts the future water-saving effect.According to the real water-saving principle and based on the remote sensing ETand target ET,this paper makes the water-intake quota plan and cutting plan.The results show that the current water-intake quantity of the demonstration area is 1.192 million m3,the accumulated water-intake quotas is 1.07 million m3,the water quantity needed to be cut is 121 000m3 and accounts for 10.2% of the current water-intake quantity.According to the water saving plan,the plan will be finished on the fifth year.Therefore,this research provides an effective method for enhancing water use efficiency and carrying out regional water-saving managements.
