城市湖泊水质优化管理技术研究

根据湖泊水质管理技术的需要，建立了城市浅水湖泊水动力生态水质模型，模型模拟的状态变量包括温度、悬浮物、等。模型率定有较好的精确度，已经为南京市玄武在清淤、截污和引水等工程共同运行的条件下做了水质模拟和预测。共结果为玄武湖水质优化管理技术的最终决策提供了科学依据。

Optimum Management Techniques of Water Quality for Urban Lakes

According to the needs for management techniques of water quality for lakes, the water quality models of hydrodynamics and ecology for urban shallow lakes are developed. The state variables simulated of models include temperature, suspended sediment, phosphorus, nitrogen, phytoplankton, transparency, dissolved oxygen and biochemical oxygen demand etc. Calibration of models has a fairly good degree of accuracy. The simulation and prediction of water quality on the condition for the joint operation of dredging, nutrient diversion and water diversion for Lake Xuanwu have been done. The results provide scientific basis for final strategic decision on the water quality management techniques for Lake Xuanwu.
