径流模拟是河西内陆河地区水文研究中最基本、最重要的一个环节,也是研究其它水文问题的基础.目前广泛应用在河西地区的径流模拟模型大致分为系统理论模型、概念模型和分布式模型三类.但是这些模型各自有哪些特点,应用中应注意哪些问题,却缺少宏观的认识.总结了这三类模型在河西内流河区应用的代表性研究成果,并结合当前所应用模型存在的问题,探讨了研究区未来水文模型可能的发展方向.
Runoff simulation is the most basic and important link in the hydrological research of inland river area in Hexi and also the basis for studying other hydrological problems.Currently runoff simulation models widely used in Hexi area can be divided into system theory model, conceptual model and distributed However, what are the characteristics of these models, what problems should be paid attention to in the application, but lack of macroscopic understanding.The paper summarizes the representative research results of the application of these three models in the Hexi River flow area, combined with the current applied model The probable development direction of the future hydrological model in the study area is discussed.
