摘要: 五里湖的浮游藻类是相当丰富的,种类较多,数量亦较大。依照它们在一年中出现的情況,可分为3类:(1)显著种类——在一年的某一个或一个以上的时期中,个体数量的增减,不但显著地影响到它们所属门类的数量变化,甚至影响到整个浮游藻类数量的变化。在各类藻类中,这样的种类都不多;但是,对浮游藻类的数量变化来说是首要的。Abstract: By analysing the plankton algae of Lake Wu-li, we may briefly summarise the results as follows:
1. The plankton algae are rich in species. The most important elements of them are the species belonging to the Chrysophyta and Bacillariophyta, which represent an average of 77 per cent of the total phytoplankton population.
