摘　　要：近年来,沿海各地通过填海造地的方式向海洋要地,建设港口及旅游业,导致填海工程对所在海域水体交换能力发生变化,影响水环境。本研究针对北戴河新区拟建人工岛,对不同功能建设方案进行研究,运用MIKE21 flow model模块探讨研究人工岛后在不同开口条件下所在海域的水体交换、污染物扩散及污染物存留率的变化规律,进而评价人工岛对水环境的影响。在考虑人工岛景观与自身净化能力达到要求的前提下,综合考虑人工岛和水环境的诸多因素,给出了可供规划参考的人工岛推荐方案。Recently, many sea reclamation projects have been carried out along China coastal line in order to construct port and develop tourism, which results in the change of water exchange capacity and impacts local water environment. Based on the proposed artificial island in Beidaihe new district, the schemes that consider different functions are compared and analyzed, MIKE21 flow module is used to study the variation of water exchange, pollutants diffusion and retention rate under the condition of different entrances of artificial island. In addition, an evaluation is made for the effect of artificial island on local water environment. At last, a suitable layout plan of artificial island is put forward by considering relevant factors, and the artificial island layout must meet the landscaping and self-purifying requirements.
