Abstract

This article used the data of biology, hydrology and chemistry, which were acquired by the investigation of 12 fixed spots in JiaoZhou Bay from May to November in 1991.

The ecological properties of the red tide plankton were concluded into three types: eurythermal and euyryhaline type, the type of little high-temperature with low salinity, and the type of little low-temperature with high salinity. In this article, the relation between the distribution of red tide plankton and environment of these 7 months was discussed briefly. And valuable suggestions of eutrophication prevention in Jiao Zhou Bay were put forward on basis of these discussions.
