分层水资源网络及其应用

Layered water resources network and its application

以水资源系统概化方法为基础,提出分层水资源网络的理论和方法,以不同水源运动过程为中心对实际中各类水源运动过程进行划分,分割出包括地表供弃水、河网输水、污水排放、外调水传输和地下水等多层水源网络。通过分层网络系统可以描述不同物理意义的水力联系和水量平衡关系,量化表达不同网络水源之间的相互转换和影响关系,从而明晰不同水源运动转化过程,以便于从方法上简化计算过程,并以该方法为基础构建了水资源模拟模型并应用于海河流域的水量平衡模拟,检验了其有效性。

The theory and method of layered water resources network is introduced based on the method of conceptualizing water resources system. The movement process of varied water sources is divided according to actual situation and multi-layer water resources network that separates the surface water waste, river network transportation, effluent discharge, outside water transportation and underground water etc. is worked out. It demonstrates the inter-transaction and influence of varied water sources in the network quantitatively by means of describing hydraulic connections of various physical meanings and relationship of water balance. It presents a clear transformation process of varied water sources that may simplify calculation process, which provide a base for establishing and testing water balance simulation model applied in the Hal River Basin.
