大陆坡上的生物具有随着深度而分带的特征.横穿大陆坡动物群的变化好象比深洋其它环境动物群的变化要快些,但动物窄带形成的原因还不清楚.可能有多种原因,如因食物来源的缩减而产生的竞争、很有效的捕食、压力对酶的影响等,还有各种条件如极低的溶解氧或沉积物物理性质方面的变化的影响.大陆坡上动物群的组成不完全是独特的,它们具有大陆架和大陆隆生物群的物种,但是大陆坡仍然可以被认为是一个特殊的生物区,其生物的丰度和生理学作用的速率界于大陆架生物和深海生物之间.横跨大陆坡的生物丰度和生理学的变化速率并不呈缓慢的梯度变化.在陆坡的根部堆积着来自淺水富含有机质的沉积物,从大陆坡根部到具有更真实海洋条件的大陆隆有一个重要的过渡带.用生物学的标准来看,大陆坡上的石油和磷酸盐矿产资源可能大部分出现在过去具有上升流、高生产率和低氧浓度为特征的区域内.象生物群本身一样,这些资源也将成带状分布.因为在有机物质的再矿化作用中,大陆坡的深度和范围具有重要的意义,为了勘探以及利用深海资源必须记住:正常生物作用的改变可能有害地影响那里自然界生命的生物化学循环.
The creatures on the continental slope are zonable with depth, and the changes in fauna across the continental slope seem to change more rapidly than those in other deep-sea fauna, but the reason for the formation of narrow bands in animals is not clear. Various causes, such as competition from reduced sources of food, effective predation, the effect of stress on enzymes, and the effects of varying conditions such as very low dissolved oxygen or changes in the physical properties of sediments. The composition of the uphill fauna is not completely unique: it has species of continental shelf and continental dinoflagellates, but the continental slope can still be considered as a special biological zone whose abundance and physiological role are bound by the continental shelf Biological and deep-sea creatures across the continental slope of the biological abundance and physiological changes in the rate of change does not show a slow gradient changes in the slope of the accumulation of sediment from the shallow organic matter-rich sediments from the continental slope root to have There is an important transitional zone between the continents of a more real ocean. Using biological criteria, most of the oil and phosphate mineral resources on the continental slope may have appeared in the past Upwelling, high productivity and low oxygen concentrations, and like the biota itself, these resources will also be banded because the depth and extent of the continental slope are of major importance in the remineralization of organic matter , It is important to keep in mind that for exploration and exploitation of deep sea resources, changes in the normal biological role can adversely affect the biochemical cycle of life in nature there.
