摘　　要：流域水平衡分析是进行水资源科学评价与合理配置的基础,传统的流域水平衡分析大多是基于有限的站点观测资料和简单的集总式模型,很难适应考虑水循环空间变异性的复杂大流域水资源综合管理的需求。本文基于分布式水文模拟技术,探讨了一种能够考虑流域内部上、下游关系的水平衡分析方法。并以海河流域为例,构建分布式SWAT模型,对海河流域及水资源三级分区的水平衡状况进行分析,在此基础上探讨海河流域维持健康水平衡关系,降低流域蒸发,进行农业真实节水的必要性和有关对策。Basin level water analysis is the base for scientific water assessment and rational allocation. Traditional basin level water balance analysis mainly adopted simple lumped models based on bruited station data. It is hard to meet complicated basin water resource management when consider spatial changes of water cycle. This paper probed into one water balance analysis way with relationship of upstream and downstream considered based on distributed hydrologic simulation technique and take Haihe River Basin for example. Haihe River Basin is located in North China, which spatio-temporal variability of precipitation and evaporation is relatively great. So we built distributed hydrological model using SWAT, base on hydrological process the water balance of the Haihe River basin and the third-level water resource regions is analyzed. According to analysis results, the article also discussed the necessity and countermeasures for maintaining healthy water balance and reducing basin evaportransprition to carry on real water saving in agriculture.
