摘　　要：以福建某人工岛为例,进行了内河道换水计算研究。为兼顾景观和环境,人工岛内设置内河道,河道两端设闸门。根据外海潮位和内河保证水位等水文条件,进行人工岛内河道换水计算研究。得到开闸时机、换水时间、不同情况下水体交换量和内河道水体流态图,并推荐了合理的换水方案。In this paper, water exchange in the inner river course for an artificial island in Fujian was studied. To build an artificial island, a river course was set taking into account of the landscape and the environment, with two sluices at the end of the river course. According to the hydrological conditions such as the tidal level of open sea and the guaranteed water level in the inner river, water exchange of the inner river course was analyzed. The occasion of sluice opening, the time of water exchange, the exchange capacity and the flow state figures of river course were obtained, and the reasonable scheme for water exchange was proposed.
