原生动物

It can be seen that the species composition of zooplankton comprised mainly of protozoa,followed by rotifers,copepods and cladocera,with an average density of 3.98×10~3ind/L.

从中可看出浮游动物种类组成以原生动物为主，其次是轮虫，桡足类和枝角类最少，平均密度为3.98×10~3ind/L。

Species of zooplankton were identified in Qiaodun Lake, with 45 being protozoa, 37 rotatoria, 19 cladocera, 6 copepoda.

From Chaotianmen to Zigui,the Shannon-Weaver diversity index of phytoplankton changes undeely.4 the impact of sediment deposition on zooplankton in the waters studiedAccording to the results of the experiment, we had learnt that the species composition of zooplankton sampled had the same tendence-the species was from less to more, and the biomass was also gradually increasing. Particularly Copepoda had increased significantly in the type and quantity. The main of zooplankton at each sampling situs were protozoa and rotifers.

朝天门江段到秭归江段的浮游植物的Shannon-Weaver多样性指数呈波浪式变化，整体有下降趋势。4研究水域泥沙沉降对浮游动物的影响从本次实验的结果来看，四次采样浮游动物种类组成都有同一个趋势：种类由少到多，生物量也逐渐增大，特别是桡足类在种类和数量上都增加明显，各采样点的浮游动物以原生动物和轮虫为主。

Five water sampling collected from Miyun Reservoir were observed quantitatively. Thirty-six species of zooplankton including 11 protozoan, 15 rotifers,6 cladocero and 4 copepoda were found. The results showed the eutrophicational feature, such as lower biodiversity ,miniaturization and more amount.

浮游动物共检出4门，30属，36种；浮游动物群落具有原生动物数量多，轮虫次之，枝角类与桡足类量少的特点，呈现出浮游动物数量大、小型化、多样性低等伴随水体富营养化出现的特征。

Inoculating the three protozoa reduced soil microbial biomass C. But corn straw decomposition was not decreased, even increased when inoculating Colpoda cucullus. The protozoa, in particular, Colpoda cucullus also had some effects on N and P transformation.

向土壤接种原生动物，虽然减少了土壤微生物生物量，但却促进了玉米秸秆分解，还对土壤有效磷含量、氮素转化产生显著的影响，其中Colpoda cucullus效果最明显。

Results showed that 57 species in total were identified. Among them copepod was the dominant group, containning 20 taxa. The zooplankton community was composed of 18 rotatoria species, 8 cladocera species, 2 tunicata species, and 1 species in each of Protozan, polychaeta, heteropoda, medusae and euphausiacea, and 2 species unidentified.

经鉴定有浮游动物57种，其中桡足类占优势，有20种；其次为轮虫和枝角类，分别为18和8种；此外，被囊动物2种，原生动物、多毛类、异足类、水母类、糠虾类各1种；还有阶段性各种幼虫以及未知种类2种。
