优化调度模型在城市景观水体中的应用研究

Optimal water dispatching model for urban landscape and its application

为满足城市景观水体水量水质的要求,实现合理经济高效的景观水体运行维护,建立了城市景观水体水量–水质耦合的优化调度模型,并应用该模型对天津市滨海新区某景观水域进行了实例研究。研究表明:在合理确定运行参数如补水方式、补水周期、循环周期等的基础上,通过优化调度,可最大限度地降低景观水体的日均运行维护费用。研究成果可为城市景观水体治理技术方案优化决策、水质管理和运行维护提供科学依据。

An optimal water dispatching model for landscape water quantity and quality has been developed and applied to Tianjin Coastal New Area, as a case study, to meet the demand on maintain urban landscape water quantity and quality and achieve high economical efficiency of water operation and maintenance. The present study shows that this model is able to minimize the daily cost of urban landscape water operation and maintenance under the condition of reasonable operation parameters such as the volume of water replenishment and the periods of replenishment and circulation. The results are helpful to optimization decision on the technical schemes of urban landscape water treatment, water quality management, and water operation and maintenance.
