摘要:

2016年5月和8月浒苔暴发前后，分别对日照近岸海域浒苔暴发区进行了两个航次的浮游植物断面调查。两个航次中，硅藻都占据了调查海域浮游植物组成的主导地位，在种类数上和细胞丰度值上都占了较大的比例。8月航次细胞丰度明显高于5月航次，这与调查海域的历次调查结果相一致。应用PRIMER软件中的单变量分析得到群落种数（S）、丰富度（d）、香农-威纳指数（ShannonWeaner index）（H′）和均匀度（J），从多样性指数分析可以看出，5月航次的生物多样性优于8月航次，5月航次调查海域浮游植物种类数量和空间分布都较均匀。两个航次中出现的优势种存在较大差别。

Abstract:

To analyze the phytoplankton species composition and biodiversity for green tide of Enteromorpha prolifera occurrence areas in Rizhao coastal region,two investigations were carried out during May and August in 2016.The species (S),abundance (d),Shannon-Wiener diversity index (H′) and evenness index (J) of phytoplankton were also studied by using PRIMER.The results were consistent with the historical findings.It showed that Bacillariophyta dominated the phytoplankton community,with larger proportion in specie and density.The phytoplankton density was higher in August,while biodiversity was higher in May.The species and spatial distribution of phytoplankton are relatively uniform in May.But the dominant species in the two survey were quite different.

Key words: Green tide,Phytoplankton,Abundance,Biodiversity,Dominant species
