The zooplankton specimens were investigated in Pacific saury fishing grounds of northwestern Pacific Ocean from July to September in 2005, and then were analyzed by species, amount and distributions.

根据2005年7-9月于西北太平洋公海秋刀鱼渔场所采集到的浮游动物的有关数据，对调查海域表层浮游动物的组成、数量和分布进行了研究。

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 number of zooplankton species in the Changjiang Estuary and their distributions are complicated.

长江口浮游动物丰度和分布具有不确定性，水团的季节变化，外海水和冲淡水交汇的位置是影响长江口浮游动物分布特征的重要因素。

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。

Only 8 species of Cladocera and 5 species of Copepoda were observed.

共鉴定浮游动物134属217种，其中原生动物95属153种，占浮游动物物种数的71%；轮虫27属51种，占23%；枝角类7属8种，占4%；桡足类5属5种，占2%。

The biomass of zooplankton changed relatively intensely, especially Cladocera、Copepoda and Young animal, and the biomass of the zooplankton will gradually increase.

随着泥沙的逐渐沉降，浮游动物生物量变化相对激烈，尤其是枝角类、桡足类和无节幼体，水中浮游动物生物量将逐渐增加。

Copepoda was dominant group in zooplankton of the Changjiang Estuary. The abundance of them overwhelming dominated all zooplankton.

三、桡足类是长江河口浮游动物中的优势类群，其数量分别在枯、丰水期浮游动物总数量中占绝对优势。

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。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
