海洋底栖动物

香港维多利亚港疏浚淤泥对海洋底栖动物的毒性累积效应

Toxicity accumulation effect of the sludge , dredged from Victoria Port of Hong Kong , to marine benthonic animals

海洋底栖动物活动性小、地区性强，可以较好地反映水质和底质的污染状况，在海洋污染生物学指标中具有特别重要的意义。

Marine benthos are characterized by narrow activity and special territory distribution and can be used to indicate the quality of water and the polluted condition of sediments , which plays an important part in the biologic indication of marine pollution .

海洋大型底栖动物能对自然和人为活动导致的水和沉积物质量变化做出可预测的响应，因此利用底栖生物作为环境监测的生物指标和进行环境质量评价的生物指数已经得到了广泛的认可。

Abundant researches have demonstrated that macrobenthos communities responds relatively rapidly to natural and man-induced changes in water and sediment quality , so benthic communities are used frequently as bio-indicators of marine monitoring and biotic indices of assessing the marine ecosystem health .
