| 摘 要： | 以石家庄市正定湖为例，基于EFDC水环境数学模型确定引水规模，分析风场因素对人工湖调水置换效果的影响，并根据不同风向、风速的风场叠加后湖区水龄模拟结果，探明最有利于调水的外部环境条件：正定湖最佳引水风向为偏北风，风速为5m／s时，实现80％水体交换需要2～3d。

| Abstract: | Taking Zhengding Lake in Shijiangzhuang City as a case study, the EFDC model was used to determine the scale of water diversion, and the influence of the wind field on the water exchange of the artificial lakes was analyzed. According to the simulation results of the water age of the lake with different wind directions and at different wind velocities, the most favorable environmental conditions for water diversion were found as follows： when the wind direction that was most favorable for water diversion was slightly northerly and the wind velocity was 5 m/s, the exchange of 80% water took two to three days. |
