摘要
海冰的大规模开采和淡化会导致周围水体的盐分增加。本文基于ECOMSED模式,建立了渤海潮流驱动下的盐分扩散模式,来定量的分析渤海淡化期增量盐分的扩散情况。结果表明,环渤海沿岸利用海冰的城市中,黄骅和鲅鱼圈的水交换能力最弱,盐分不易扩散;其次是曹妃甸和葫芦岛;长兴岛邻近外海,且水深较深,水交换能力最强,盐分容易被稀释。
The salinity in seawater will increase when the sea ice are exploited and desalinated extensively. Based on the ECOMSED model, a salinity diffusion model driven by tides was constructed to analyze the diffusion of the increased salinity quantitatively during the ice desalination period in the Bohai Sea. The results showed that among the cities which utilized the sea ice around the Bohai Sea, the water exchange in Huanghua and Bayuquan is the weakest with the salinity not easy to diffuse; the water exchange in Caofeidian and Huludao is stronger than those mentioned above. The outer sea of Changxingdao is deep, so the water exchange is strong and the salinity is easy to diffuse.
