旱区城市雨水资源化系统调控过程分析

Analysis on Regulation Process of Arid Urban Rainwater Utilization System

为了解决现代化城市水资源问题,笔者结合自然水循环和人类活动二元驱动力共同作用的水循环理念,通过城市雨水资源化与水循环调控,构建了城市降雨径流及传输调控系统模型框架,包括资料输入模块、单元水文模块、城市管网及沟渠汇流传输模块、河网汇流模块和雨水资源化模块5个部分,探讨了模型中各子模块的计算方法,为建立更加准确和实用的城市降雨-径流模拟模型提供参考。

In order to solve the problem of water resources in modem cities,the author combines the concept of water cycle with the dual driving force of natural water cycle and human activities,and constructs the model framework of urban rainfall-runoff and transmission control system through urban rainwater utilization and water cycle regulation,including data input module,unit hydrological module,urban pipe network and ditch confluence transmission module,river network confluence module and rainwater resource utilization module,and the calculation method of each sub-module in the model is also discussed,which provides a reference for establishing a more accurate and practical urban rainfall-runoff simulation model.
