摘要:
文中通过潮流和污染物扩散方程的嵌套计算，模拟分析了唐山湾国际旅游岛月岛度假区项目考虑取沙与否两种方案下，月岛规划区内的水题交换能力。原控规方案水体交换能力和原控规取沙后方案相当，取沙后交换能力稍微优于取沙前。总体来说人工岛实施后两个方案水体交换能力很好，约72小时后，两个方案岛内主要水域的水体交换率均大于60%。
By nested calculation of tidal flow and
pollutant diffusion equation, and under the consideration of whether dredging
sand or not of Moon Island Tourist Resort project in the Gulf of Tangshan international
tourism island, this paper simulates and analyzes the water exchange capacity
of this area. The water exchange ability of the original planning scheme agrees
well with the dredging sand scheme, the exchange ability with the Dredging Sand
Scheme is a bit better than before. In general, the water exchange ability of the
two schemes after the artificial island putting into effect is very good, and about
72 hours later, the water exchange rates of the island’s main water area in two
schemes are both greater than 60%.
