In the pelagic subsystem,there are 4biological state variables which were represented by functional groups:flagellate,diatom,pelagic bacteria and zooplankton.In the benthic subsystem,there were 5 biological state variables represented also by functional groups:macrobenthos,meiobenthos,aerobic and anaerobic bacteria,and shrimp-which is actually epibenthos.

将浮游亚生态系又划分为4个功能群，分别为：鞭毛藻、浮游硅藻、水体中细菌和浮游动物，将底栖亚生态系划分为5个功能群，分别为大型底栖动物、小型底栖动物、底栖厌氧菌、底栖好氧菌，对于营底上生活的对虾也划分在这一亚生态系中予以考虑。

To evaluate the toxicity of the sludge, dredged from Victoria Port of Hong Kong , to marine benthonic animals lived in its pouring region, the toxicity test of the sludge to marine benthonic animals, including benthonic shellfish and crustacean, has been conducted.

为了评价香港维多利亚港疏浚淤泥对倾倒海区海洋底栖动物的影响，进行了两种底栖贝类和一种底栖甲壳类的生物毒性累积试验。结果表明，试验底栖贝类结蚶和缢蛏暴露在试验淤泥中240h和480h后，随暴露时间的延长，累积率增大。

Brey's (1990) empirical formula was used to calculate the secondary production and P/B ratio of macrobenthos according to macrobenthos biomass and abundance obtained in Shenhu Bay. The results showed that the mean annual secondary production and P/B ratio were 0.599g/(m^2a) and 1.561 respectively.

根据各个季节获得的大型底栖动物栖息丰度和生物量，采用Brey (1990)的经验公式进行了大型底栖动物次级生产力和P/B值的计算，得出深沪湾潮下带大型底栖动物年平均次级生产力和P/B值分别为0.599g/和1.561。

The studies of relationship between zoobenthos and environmental factors were conducted in this paper,and how to protect and utilize zoobenthos has been suggested. zoobenthos ; environment factors ; effect ; protect and utilize

底栖动物的生长繁殖、种类组成和现存量在不同水体和区域间存在着明显的差异，环境因子对底栖动物的影响相当复杂，不仅因子众多，而且各个因子对底栖动物中不同类群的作用并不完全一致，因此对这方面进行研究具有重要的意义，以下从理化因子和生物因子对底栖动物影响来加以概述。1理化因子对底栖动物的影响1.1水质对

When we used those two multivariate statistic analytical techniques to study the spatio-temporal variation laws of benthic community structure at Shenzhen Bay, the results indicated that: 1 There was not obverse difference in intertidal benthic community structure between Futian, Shenzhen and MaPi, HongKong in Shenzhen Bay in Spring, 2000. However, there was continual gradient change in community structure from outer bay to inner bay. 2 There was obvious deference with the respect of benthic community structure between station C and stations Al, A2, A3 in transect A and station B in transect CBA in Shenzhen Bay. There being no benthos at station C in Summary, 2000, it indicated that station C had been polluted very heavily. 3 Deferent seasons and deferent tide sites are the most two important factors which play influence on benthic community structure at stations Al, A2, A3 and B3 in Shenzhen Bay.

用这两种多变量方法研究深圳湾底栖动物群落结构时空差异，结果表明(1)2000年春季深圳湾底栖动物群落结构组成在深圳福田一侧与香港米埔一侧并没有明显的差异，而是沿湾外向湾内呈现连续的梯度变化；(2)在深圳福田一侧的C断面的底栖动物群落结构与A、B断面有明显的差别，2000年夏季在C断面没有采到任何底栖动物，表明C断面已经遭受了严重的污染；(3)季节和潮区是影响深圳湾A1、A2、A3、B3站位底栖动物群落结构组成时空差异的两个最重要的因素。

In terms of horizontal distribution, stations near the coast have higher abundance and biomss of meiofauna. In terms of vertical distribution, 74.33% of total meibenthos is found in the surface sediment 0-2cm, 22.31% in 2-5cm and 3.36% in 5-8cm sediment.

小型底栖动物的水平分布呈镶嵌式分布，沿岸站位小型底栖动物的丰度和生物量较高；垂直分布上，小型底栖动物分布于沉积物0-2、2-5cm和5-8cm的数量比例分别为74.33%、22.31%和3.36%。

The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。
