本文讨论了南充市郊西河水域底栖无脊椎动物区系组成。

The paper also emphasized the zoology index that belongs to ecosystem instinctual characteristic and introduced the estimate methods that used algae, benthic invertebrate and fish as indicator.

着重阐述了系统本身特性中的生态指标，列举了以着生藻类、底栖无脊椎动物和鱼类为指示生物的评价方法。

We conclude that there is a strong correlation between the benthic fauna and environmental factors, and also for the benthic species composition, density and environmental factors.

从而得出底栖动物与主要环境因子相关系数都很高，底栖动物物种组成、密度与主要环境因子间的相关性都很强。

本文从潮间带沉积物的粒径、分选系数及底栖生物群落结构阐明潮间带生态现状。

Sediment quality in waters not only affect the benthic organism, but also has close relation with the water quality due to the frequent pollutant interchanges between the sediment and overlaying water. The polluted sediment often becomes the potential source to pollute waters.

水体沉积泥沙质量不仅对底栖生物具有影响，而且由于泥沙与上覆水体相互间频繁的交换作用，泥沙质量与水体水质也有着密切的关系，污染的泥沙往往会成为水域的潜在污染源。
