根据１９９８年８月台湾海峡温度、盐度、叶绿素a的观测结果，讨论了调查期间叶绿素 ａ的垂直分布特征。结果表明，夏季台湾海峡西部海城存在明显的上升流，较高的叶绿素ａ含 量均位于低温高盐的涌升水中。叶绿素ａ最大值出现在上升流区边缘、温跃层附近。台湾海峡 东部海域由高温、低盐、低营养盐水占据，叶绿素ａ含量明显较海峡西部海域低。

Based on the observations of temperature, salinity and chlorophyll a in Taiwan Strait in August 1998, the vertical distribution of chlorophyll a during the survey period was discussed. The results show that there is a clear upwelling flow in the western part of the Taiwan Strait in summer, and the higher chlorophyll a content is located in the rising water of low temperature and high salt. The maximum value of chlorophyll a appears at the edge of the upwelling region and near the thermocline. The eastern Taiwan Strait is dominated by high-temperature, low-salt and low-nutrient salt water, and the content of chlorophyll a is obviously lower than that of western part of the Strait.
