浮游藻是水域有机物的生产者,作为食物链的基础环节,通常以它的种类及细胞数量来估价海洋水产资源的贫富;又因浮游藻随波逐流的生活方式,不同种类对海洋环境适应能力不同,具有不同的生物学特性,往往以此作为某些海洋环境因子的指标。因此,了解某一海域浮游藻的种群结构、细胞数量分布以及浮游藻种、量的季节变化,可为开发利用该水域的生物资源、研究海洋环境提供基础资料。对于胶州湾的浮游藻类的研究,到目前为止,尚未见详细报道。为了了解这一海域浮游藻的基本状况,我们于1977 Phytoplankton is the producer of organic matter in the water. As the basic link of the food chain, it usually evaluates the rich and poor of the marine aquatic resources by its species and cell number. Because of its different abilities to adapt to the marine environment, With different biological characteristics, they are often used as indicators of some marine environmental factors. Therefore, knowing the population structure, cell number distribution and phytoplankton species and seasons in a certain sea area can provide basic information for developing and utilizing the biological resources of this water area and studying the marine environment. The research on phytoplankton in Jiaozhou Bay has not been reported yet so far. In order to understand the basic status of phytoplankton in this area, we in 1977
