摘要:

2006年6-7月对黄、东海海区叶绿素a现场取样分析。结果显示，叶绿素a的分布整体上呈现从近岸到远海降低的趋势。受长江冲淡水和上升流的影响，高值区主要在28°~32° N，122-5°~123° E之间。光照条件和营养盐等是影响夏季黄、东海海域叶绿素a分布的主要因素。

Abstract:

The horizontal, vertical and sectional distribution of chloropyll a was studied in detail based on the data obtained by field observations from June to July, 2006 in the Yellow Sea and East China Sea. It was found that, the values of chloropyll a decreased from the shore to open sea in the horizontal distribution. Affected by Chang Jiang River and upwelling water, the high values were found at an area between 28°-32° N，122.5°-123° E. The condition of illumination and nutrients was the main factors of chlorophyll a distribution.
