【 摘 要 】

After the construction of artificial island group, the good water exchange ability is beneficial to improve the water environment quality and improve the landscape effect of the island group. In order to solve the water exchange in the island group, a numerical model based on solving the hydrodynamic and advection-diffusion equations was used to calculate the water exchange of artificial island group in Weifang, China. The water exchange rate was obtained by calculating the concentration variation of dissolved conservative tracer. Based on the analysis of water exchange and influence factors, the suggestion of optimization was proposed. Fist the narrow waterways should be avoided and the most effective way to enhance the hydrodynamics for weak flow region is increasing exchange of channel.
