底栖动物

The benthic meiofauna was quantitatively investigated from 19 stations in the sea areas of the First-phase Project of Yangshan Deepwater Port in November, 2005 and ten meiofauna groups, including nematodan, copepodan, polychaetan, bivalvian, ostracodan, amphipodan, tanaidacean,cumacean, gastropodan and foraminiferan, were recorded.

2005年11月对洋山深水港一期工程海域19个站位的小型底栖动物进行了调查，共获得10个主要类群，包括线虫、桡足类、多毛类、双壳类、介形类、端足类、异足类、涟虫、腹足类和有孔虫。

In this paper, in terms of biodiversity restoration of mangrove frola and benthic fauna , main problems in mangrove restoration in China were analyzed and some basic research strategies w.

从红树植物及与之密切相关的底栖动物的多样性恢复出发，分析了我国当前红树林恢复存在的主要问题，并提出了对此需要着重进行的基础研究思路。

The aquatic ecology of the Yangtze River Basin was investigated and evaluated by using benthic invertebrate as indicator species.

采用底栖动物作为指示物种对长江流域的水生态进行了调查研究和生态评价。

The results showed that the community structure of macrozoobenthos was very simple. The main dominant species are Chironomus plumosus and Limnodrilus udekemianus.

结果表明，盐碱池塘底栖动物群落结构简单，主要优势种是羽摇蚊幼虫和奥特开水丝蚓。

Ciliata in Yanghe River and Relation with Water Quality Pollution

本文根据浮游及底栖动物种群结构和数量分布特点，对秦皇岛市洋河进行了初步评价。

Benthos feeders were bottom-dwelling or demersal species.

食底栖动物的鱼类，主要是一些底层和近底层鱼类。

The habitat condition was more diversifiable and complicate.

河口上游区域的大面积围垦造地及环境污染是降低底栖动物食性功能群多样性的主要原因，缺乏杂食和碎屑食者，且肉食者物种很少，说明了区域生境破碎化明显，导致营养源的减少以及食物链的简单化。

However, the high abundance of ostracodan and foraminiferan was distributed in deeper water while the high abundance of nematodan was presented in coastal water, and they could meet the distribution rules of these fauna groups.

但总的来说，介形类和有孔虫的高丰度区主要分布于洋山港区附近的深水区，线虫主要分布于近岸海域，这符合它们大体的分布规律。关键词洋山深水港；小型底栖动物；丰度；生物量；分布

Alterniflora salt marsh presented a trend of increasing gradually from the upper to the lower region of the Yangtze Estuary. 21 species were identified. Assiminea sp., Notomastus latericeus, Cerithidea largillierl, Glauconome chinensi, Gammaridae sp.

2沿着长江河口纵向梯度，互花米草盐沼的大型底栖动物群落的物种数和多样性从上游到下游呈逐渐增多的趋势，丰度主要受到沉积物粒径和互花米草高度的影响。

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。
