摘要

本文的目的是比较分析克罗地亚溪流和河流中底栖大型无脊椎动物的组成与不同的物理化学因素，特别是营养物质的关系。样品按AQEM法采集。在所有样点共记录到20个分类群，其中包括turbellia、Gastropoda、bivalia、oligochaia、Hirudinea、甲壳目、Ephemeroptera、Odonata、Plecoptera、Heteroptera、Trichoptera、Coleoptera和双翅目。水温对底栖大型无脊椎动物组成的影响最大，与底栖大型无脊椎动物组成成反比。铵态氮、硝酸盐、亚硝酸盐、全氮、正磷酸盐和全磷的富集对蜉蝣目、翼翅目、毛翅目和双翅目的影响主要是通过降低其多样性。

Can Ephemeroptera, Plecoptera, Trichoptera (EPT) assemblage reflect nitrogen and phosphorus load in the riverine ecosystem?

The aim of this paper is to make a comparative analysis of benthic macroinvertebrate compositions in streams and rivers in Croatia with relation to different physical-chemical factors, especially nutrients. Samples were collected according to the AQEM method. At all the sites, 20 taxa were recorded of which Turbellaria, Gastropoda, Bivalvia, Oligochaeta, Hirudinea, Crustacea, Ephemeroptera, Odonata, Plecoptera, Heteroptera, Trichoptera, Coleoptera and Diptera were included in the present study. Water temperature mostly affected the composition of benthic macroinvertebrates to which it was inversely proportional. Nutrient enrichment, i.e., higher concentrations of ammonium, nitrates, nitrites, total nitrogen, orthophosphates and total phosphorus mostly affected Ephemeroptera, Plecoptera, Trichoptera and Diptera, by decreasing their diversity.
