摘　　要：为加深对山东半岛东部养殖区的海流、海温变化特征,及其与该地区生态特征分布之间关系的认识,应用短期资料的潮流准调和分析方法,计算了烟墩角海域两个测站的O1,K1,M2,S2,M4,MS46个主要分潮的北、东分量潮流调和常数,并给出了各测站在各层的潮流椭圆要素。结果表明:该海区水温呈现层化结构,在1天内呈现两个波动,与N-S向潮流变化关系密切。海区除湾内表层外属日潮性质外,潮流属于正规半日潮流性质,半日分潮流的北分量大于东分量,呈现典型往复流特征,最大流流向多为南北向。分析结果也反映出表层、中层的浅水分潮在观测海流中所占的份额高于底层的浅水分潮。We analyzed water characteristics based on water temperatures and tidal current at Yandunjiao. To col- lect these data, we observed the surface and bottom water layers for 25 hours. Using the tidal current quasi-harmonic method for short term data, we calculated the harmonic coefficients of O1, K1, M2, S2, M4 and MS4 tidal current constituents in north and east components, along with the tidal current elliptic factors. The sea water showed stratification with two fluctuations, which was closely related with the N-S tidal currents. The tidal current in the studied area was classified as regular semidiurnal current, except the surface layer in the Yandunjiao Bay. The north component of semidiurnal current was generally stronger than the east one from our result. The semidi- urnal current was reversing current in our observed area with the N-S direction. The ratio of shallow water tidal current constituent to observed current in surface layer was greater than that of the bottom one.
