Suggestion on compositions of freshwater zooplankton vs photozoa

以往国内的研究中淡水浮游动物的类群包括原生动物、轮虫、枝角类和桡足类。原生动物与另外三类相比,包括的种类多,鉴定比较困难,而且在生态系统研究中原生动物与另外三类的侧重点有所区别。根据国外目前研究的趋势,建议将原生动物与轮虫、枝角类和桡足类分开研究,即一般的浮游动物研究类群不包括原生动物。;Freshwater zooplankton in the previous domestic studies includes protozoa, rotifer, cladoceran and copepod. There are numerous species and difficulty in identification for protozoa compared to another three groups, and different emphases are made in ecosystem studies between them. Based on the tendency of the foreign researches, it is suggested that protozoa study is necessarily separated from rotifer, cladoceran and copepod, namely the studied groups on zooplankton comprise rotifer, cladoceran and copepod, exclusive of protozoa.
