浮游植物

The terrestrialand aquatic environmental impacts of veterinary drugs was expounded both on terrestrial environmental impacts of veterinary drugs upon plants, soil animals, soil microorganism and protozoa, and ecotoxicity of veterinary drugs to plankton, microorganism, fish and Crustacea.

综述了兽药对陆生和水生生态环境影响方面的研究进展，探讨了兽药对陆生植物、土壤动物、土壤微生物与原生生物等陆生生态环境的影响及对浮游类生物与微生物、鱼虾与水体甲壳动物等水生生态环境的影响及其生态毒理效应。

The contemporary radiations of phytoplankton and benthic metaphyte probably made a significant contribution to the Early Cambrian explosion of animals.

这一时期浮游微生物和后生植物的共同繁盛可能为早寒武世"澄江生物群"的爆发奠定了生态基础。

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.

区系中的单细胞浮游藻类包括近岸广布种116种、近岸暖水种31种、近岸温带种26种；维管束植物被划分为6大生态类群，包括盐生植物24种、水生植物22种、湿生植物35种、中生植物103种、旱生植物6种、沙生植物4种，保护区内湿地植被的建群种、优势种均为水生植物、湿生植物或盐生植物，反映了湿地植被的隐域性；维管束植物按照生活型划分，有20种高位芽植物、4种地上芽植物、54种地面芽植物、48种地下芽植物和68种1年生植物，其中地面芽植物、地下芽植物占区系植物总种数的比例较高，占52.58%，反映冷湿气候和局部低洼积水环境对区系的形成起较重要作用。

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

植物浮床技术在苗家河的示范应用研究说明：在水量交换较大的情况下植物浮床技术仍然使示范河段水质优于对照段；浮床植物根际区存在着以有机颗粒、藻类、浮游动物、底栖动物为网络骨干的根系微生态系统：&水芹菜-水蕹菜&浮床模式可实现四季净化污染河水的周年运转，在后续应用中推荐使用此模式。

Malaianus, H.verticillata et al, whose occurrence rate was 100% and weight percent was 85.6%; Secondly, it can feed on humus of organism, whose occurrence rate was 100% and weight percent was 10.0%; Thirdly, it can also feed on a little Filamentous alage, Floating algae, Zoonplankton, Oligochaeta, Tendipes, Procambarus clarkii et al, whose occurrence rate was less than 10%,and weight percent was only 5.4%.

食性 克氏原螯虾(体长3.0cm～10.6cm，体重1.6g～80.3g)的摄食种类主要是竹叶眼子菜、黑藻等大型水生植物，出现频率达100％，重量百分比达85.6％；其次是有机碎屑，出现频率达100％，重量百分比为10.0％；同时还有少量的丝状藻类、浮游藻类、浮游动物、寡毛类、摇蚊幼虫、克氏原螯虾的残体等，这些种类出现率都小于10％，重量百分比仅为5.4％。

Since mitochondria are the descendants of free-living bacteria that shacked up with the ancestor of modern animals and plants about 2 billion years ago, they have their own genes, independent of the cell nucleus.

线粒体是浮游细菌的后代，20亿年之前就与牲畜的祖先和植物共居一体。它们有自己独立的细胞核外基因。

About 11 different kinds of microphytoplankton assemblages which belong to four types are found in the core of the Du432 well.

在杜432井的岩心中共发现了11种不同的微体浮游组植物组合，分属于四种组合类型。

Crinoids, ammonoids and bivalves dwelt on the stems and lived on pseudoplanktons. They were gradually deposited on the sea bottom with increasing biomass of the dwelling organisms and lime content, and at last concretions were formed.

海百合、双壳类和菊石类栖息在植物茎干上营假浮游生活，随着栖息生物量和化学沉积物灰泥的增加，逐渐沉积在海底形成结核。

Under present conditions, the phytoplankton in Lake Okeechobee are often light-limited due to a combination of abiotic turbidity and a relatively high lake stage.

目前的情况下，在奥基乔比湖的浮游植物往往受到光照的限制，这是因为非生物混浊度和相对较高的湖水位共同造成的。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
