【摘要】 本文采用1981年8月和10月浙江近海上升流调查中一条断面的调查资料,研究分析了管水母、水螅水母种类组成和优势种——双生水母、拟细浅室水母、五角水母等的垂直分布,以及一些重要种类的昼夜垂直移动。研究结果显示,在调查海区水母类及其优势种在数量和分布上的变化与浙江沿岸上升流和台湾暖流的盛衰密切相关。更多还原

【Abstract】 Data in this paper are taken from a section of the project of "the investigation of Zhejiang coastal upwelling" during Aug. and Oct. 1981. The constitution of species of siphonophora and hydromedusae, the vertical distribution of dominant species - Diphyes chamissonis, Lensia subtiloides and Muggiaea atlantica, and the diurnal migration of some abundant species are described. The result shows that the variation in numbers and distributions of siphonophora and hydromedusae and their dominant species in the survey area are closely related to the rise and fall of Zhejiang coastal upwelling and Taiwan Warm Current.更多还原
