中文摘要：
依据2006年夏季对东海区水文化学数据的现场调查, 对台湾暖流的水文化学特性进行了初步分析, 并对台湾暖流自身的水文化学特性对东海赤潮高发区的影响进行了初步探讨。结果表明, 夏季, 台湾暖流水具有台湾海峡水和黑潮次表层涌升水两个来源, 分别构成台湾暖流的表层水和深层水。通过亚硝酸盐含量的多少能够对表层水和深层水进行明显的区分。此外, 通过对台湾暖流水文特征的分析, 发现夏季台湾暖流在浙江沿海出现的上升流给赤潮生物提供了适宜的温度。并通过对台湾暖流的营养盐含量进行分析, 发现相对于硝酸盐含量, 台湾暖流含有较高的磷酸盐浓度, 能够缓解海区“过剩氮”导致的磷限制。
英文摘要：
Service, Beijing, 100194; 3. Fujian Marine Environment and Fishery Resource Monitoring Center, Fuzhou, 350003） Abstract With field data of the continental shelf of the East China Sea in summer 2006, characteristics of hydrology and chemistry of the Taiwan Warm Current （TWC） were analyzed, and its influence on the area of high-frequency harmful alga blooms （HABs） in the East China Sea was discussed. The results show that, the TWC in summer had two origins： Taiwan Strait Water and Kuroshio subsurface water, which constituted the surface water and deep water of TWC respectively. In addition, we distinguished the surface and deep water according to the content of nitrite. Moreover, the upwelling of the TWC off Zhejiang Province could bring more phosphate, which promoted the HAB outbreak, regulated the nutrient structure of the HAB-outbreak area in the East China Sea, and relaxed the phosphate limitation that caused by excessive nitrogen.
