摘　　要：城市景观人工湖规划设计时,需在湖体水质恶化到一定程度引入新的水体进行调水置换,以确保湖区水环境质量,合理确定的引水条件将有效节约引水资源量。以石家庄市正定湖为例,基于EFDC水环境数学模型,分析了不同调水方案下湖区示踪粒子追踪模拟情况,根据示踪粒子追踪模拟结果,确定了湖区最优调水规模,并探明了湖区潜在的重污染区域和富营养化高发区,为切实保障湖区水环境质量提供了技术参考。During the design of artificial lake, the water quality is deteriorated to a certain degree so that water diversion must be applied to exchange the old water to ensure the water quality. If the design is not scientific, it will cause a great waste of water resource. Taking Zhengding Lake for example, based on EFDC, the paper analyzed the simulation state of tracer particles in the lake in different schemes of water diversion, determined the optimum scale of water transfer according to the simulative results of tracer particles, and ascertained the potential region of heavy pollution and the region of eutrophication, which supplied technical support for the guarantee of water environmental quality in the lake area.
