【Abstract】 The morphology of red tide species Gonyaulaex polygramma was described by SEM photographies. The progress and quantitative variations were studied during the period when the red tide occurred in the waters around Yantian, Dapeng Bay of Guangdong from May to June 1991. Correlation of species occurrence with environmental factors by stepwise regression analysis indicated that COD and salinity were respectively the most significant which affected the cell numbers. All analytical data were taken from May to June 1991, as well as from the same period in 1990.更多还原
