The pelagic - benthic coupling is realized by the deposition of phytoplankton and poc into the detritus and the transportation of nutrient elements from the bottom to the pelagic 水层和底栖生态系统的耦合是通过浮游植物与颗粒有机物的沉降和沉积物中营养盐的再悬浮来实现的。
Water quality - biological methods - methods of biological sampling : guidance on the design and use of quantitative samplers for benthic macro - invertebrates on stony substrata in shallow freshwater 水质.生物法.生物取样法.浅淡水中多石底层上大无脊椎动物定量取样器设计和使用指南
To understand the relationships between the benthos , sessile organisms and the constructions of artificial shallow water zone , the performance of the benthic index of biotic integrity ( b - ibi ) was used to analysis the ecological status 结果显示： ( 1 )底栖生物及附著生物皆可反映海岸浅滩生态环境的生态现况，适合作为生物指标。
First , based on in situ observation in the yellow sea and east china sea during 2000 - 2001 and other former research results , the basic characteristics of the pelagic - benthic ecosystem in this region are well understood 首先根据2000 - 2001年黄、东海生态综合调查结果和前人的分析结果，分析了黄海冷水团水域水层、底栖生态系统的基本特征。
On species composition , there are rich in general species , suitable basicity species and benthic species in the region , and a few species belong to plankton . among them , fresh water and half salty water species spread extensively , like salt species are stick out 在种类组成上，普生性种类、适碱性种类丰富，固着种类多；淡水、半咸水种类广泛分布，喜盐种类突出；真性浮游种类少。
After spraying the herbicide , the results with time show that no obvious quantitative difference occurred in benthic species composition , biomass , inhabit density and the coherent variation trend between experimental zone and controlled zone 药物喷洒后不同时段调查结果表明：试验区与对照区的底栖生物种类组成、生物量、栖息密度同步对比数量相差不明显，其随时间变化的趋势亦呈现总体一致。
Now , we may have the aid of newest diving apparatus , under , when having no heavy space , proud swim in this colour is beautiful , the benthic world that is filled with innervation and vigour , take pictures souvenir , the thing and matter that record sideswipes before you 现在我们可借助最新的潜水器材，在无重空间下，傲游于这色彩美丽、充满动感及活力的水底世界，拍照留念，记录在您眼前掠过的事与物。
We concludes that the selected herbicide for smooth cordgrass does not obviously affect community composition and the habitats of benthic species , the coherent variation trend of benthic community composition correlates with time between experimental zone and controlled zone 这表明互花米草防除药物对底栖生物群落组成结构及其生境的干扰不大，试验区与对照区底栖生物群落组成结构总体一致的变化趋势与时序有关。
Besides , you may also visit the kid s world , butterfly house , together with the world s second - longest outdoor escalator . furthermore , in marine land , you can enjoy the wonderful shows involving sea lions and dolphins . in the submerged tunnel , you can observe the 70 benthic sharks through the glass ceiling 此外，在海洋公园的海洋天地区内，可欣赏到海狮、海豚的精采表演，并可在水底隧道内，透过玻璃天花观赏70条深海鲨鱼的慑人威势。
