底栖动物

Macro-invertebrate from Annelida, Mollusca and Arthropoda were found in six sections from Baihe to Zhejiang road in the Suzhou River, among which four species were from Oligochaeta, two species from Hirudinea, five species from Gastropoda, two species from Bivalvia and several species from Insecta.

苏州河白鹤至浙江路段6个采样断面大型底栖动物隶属于环节动物门、软体动物门及节肢动物门。其中寡毛纲4种、蛭纲2种、腹足纲5种、双壳纲2种及昆虫纲摇蚊科幼虫与潜蝇蛹。

In May 2005, we surveyed water quality and benthos of the Yellow River basin in 42 sites.

2005年5月对黄河水系的42个采样点进行了水质与底栖动物的调查研究。

The benthos resource function in ecosystem of the Yangtze River Estuary was primarily discussed and we estimated and calculated their products value for the first time.

本文还对底栖动物在长江河口湿地生态系统中的资源功能做出了初步探讨，并首次估算出其物质产品价值。

The results show that 154 species were found in the area,including 60 species of Polychaeta,30 of Crustacea,28 of Mollusca and 24 of Echinodermata;the dominant species are not very distinct,the relative important or common species are Listriolobus sp.,Xenophthalmus pinnotheroides White and Cossurella dimorpha Hartman.

本次调查共获得长江口附近海域大型底栖动物154种，其中多毛类环节动物60种，甲壳动物30种，软体动物28种，棘皮动物25种，其它类群动物11种。群落中优势种的地位都不明显，只有螠虫(Listriolobus sp。)、豆形短眼蟹(Xenophthalmus pinnotheroides White)、拟单指虫为相对重要的种类。

In this paper, the species, amounts and distribution situation of phytoplankton, zooplankton and zoobenthos in Shenzhen Bay are studied.

对深圳湾浮游植物、浮游动物和底栖动物的种类、数量及分布现状进行了研究。

The results showed that the freshwater species were predominant, and 45 species of algal (5 phylums, 32 genera), in which 18 species of Bacillariophyta belong to 12 genera, 15 species of Chlorophyta one genus, 10 species of Cyanophyta 7 genera, and one specie of Euglenphyta and Chrysophyta; 37 species of zooplankton, in which 9 species of Protozoa, 14 species of Rotifera,...

结果表明，淡水种类占绝对优势，藻类5门32属45种，其中硅藻12属18种，绿藻1属15种，蓝藻7属10种，裸藻、金藻各1属1种；浮游动物共计37种，其中原生动物9种，轮虫14种，枝角类2种，桡足类8种，浮游幼虫及其它4种；底栖动物20种，分别为环节动物的多毛类7种，寡毛类2种，软体动物8种，甲壳动物2种，鱼类1种。

There are 370 kinds of plants, 194 kinds of insects, 26 kinds of fish, 17 kinds of amphibians and reptiles, 296 kinds of birds, 17 kinds of mammals, 201 kinds of phytoplankton, zooplankton 174 kinds, 23 kinds of benthic animals.

区内有植物370种，昆虫194种，鱼类26种，两栖爬行类17种，鸟类296种，兽类17种，浮游植物201种，浮游动物174种，底栖动物23种。

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。

Three sampling sites were set along the river,the classification and distribution characteristic of the phytoplankton,zooplankton and zoobenthos were sampled and investigated in Mar,2005,respectively.

本文于2005年3月针对武江乐昌河段布设了三个监测断面，分别取样调查了浮游植物、浮游动物、底栖动物的种类和分布特性。

According to the rate of occurrence and the average biomass, 33 species of phytoplankton, 34 species of zooplankton and 6 species of zoobenthods were the important species in the inland saline waters in North China.

根据出现率和平均生物量，有33种浮游植物、34种浮游动物和6种底栖动物为三北地区内陆盐水的主要种类。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
