摘要:

琼东上升流是海南岛东部沿岸的季节性上升流, 通常发生在4—9月18°30′—20°N、111°30′E以西近岸, 6—7月最强, 夏季表层水体呈现明显的低温、高盐、低溶解氧和高营养盐特征。对20世纪60年代以来琼东上升流时空特征及其影响机制等方面的研究进行了概述, 这些研究主要描述了琼东上升流的基本水文特征、年际差异以及风场和地形等影响因素的作用。对比近年来沿岸上升流的前沿研究, 指出在琼东上升流的生态动力综合调查、年际变化规律及影响机制以及与大尺度背景场的相互作用等方面还需进一步加强研究。

关键词: 琼东上升流, 时空特征, 影响机制, 概述

Abstract:

Qiongdong upwelling is seasonal coastal upwelling east of Hainan Island. It usually occurs during April-September with the strongest upwelling in June and July in the area of 18o30’ ?20oN and west of 111o30’E, where the summer surface water has low temperature, high salinity, low dissolved oxygen and rich nutrients. In this study, the temporal-spatial characteristics and mechanisms of Qiongdong upwelling are reviewed based on the studies since the 1960s. These studies mainly described basic hydrography, interannual variability, and influences of wind and topography on Qiongdong upwelling. Comparing to the latest studies in coastal upwelling, much work needs to be done on Qiongdong upwelling via comprehensive dynamic and ecologic investigations, on issues such as the interannual variability and its mechanisms, and the interaction between Qiongdong upwelling and large-scale circulation.

Key words: Qiongdong upwelling, temporal and special characters, dynamics, review
