为评价2000年至2010年海岸带开发活动对葫芦山湾水交换能力的影响,本文通过数值模拟方法计算2000年、2005年和2010年葫芦山湾海域潮流场、纳湖量和海湾水交抉率的情况。研究表明,2000年至2010年葫芦山湾岸线减少2.1km,海域面积减少约14.8km2s2000年至2005年纳湖量平均减少了0.21×108m3,水交换率平均增大了3.15%;2005年至2010年纳潮量平均减小了0.11×108m3,水交换率平均减小了0.05%,说明葫芦山湾海岸带开发活动速成海湾纳潮量减小,导致环境容量的逐年减少,是海湾污染日益加剧的主要原因之一。

To evaluate the coastal exploitations to the water exchange in Hulushan Bay from 2000 to 2010,this paper analyzed the variation in the indexes of tidal current,storage capacity of tidal water and water exchange,through the methods of the numerical simulation in 2000,2005 and 2010.The results indicated the coastline decreased 2.1km,the area of Hulushan Bay of 14.8km2.The storage capacity of tidal water decreased 21,33×10^8m2,The rate of the water exchange increased 3,15% from 2000 to 2005,The storage capacity of tidal water decreased 10.75×10^8m3.The rate of the water exchange decreased 0.05% from 2005 to 2010.It is indicated that the coastal exploitations results to the storage capacity of tidal water decreasing and the environmental capacity is decreasing.The effects of coastal exploitations are the main reasons for the environmental pollution increasingly serious in Hulushan Bay.
