【摘要】 <正> 广西沿岸位于北部湾的东北部,东起广东省的英罗港,西至东兴的北仑河口,海岸线全长约1475公里。沿岸分布有河流、港湾、岛屿等,岸线曲折,地形独特,湾内有湾,流系较为复杂。一九六○年全国海洋综合普查,对北纬21°00′以南海区的流系作过分析,但北纬21°00′以北的广西沿岸海区至今研究甚少。本文基于近期的调查资料,从计算余流入手,对广西沿岸海区的余流特性进行初步分析,以期了解基本分布状况和变化规律,为北部湾的余流研究和海洋资源开发等提供参考。更多还原

【Abstract】 Based on the data obtained from the recent coastal zone survey and the discussion on the calculations, this paper analyses the distributions and contributing factors of the residual currents in the coastal region of Guangxi Province. Results show that the coastal residual current speed in the west is larger than that in the east, the current speed in summer is larger than that in winter,and the current speed on the surface is larger than that at the bottom. The maximum residual current speed is 34.0cm/s, the minimum is 1.9 cm/s. The residual currents are closely related to the coastal topography, runoffs and monsoons.更多还原
