河涌中的水栖寡毛类与沉积物中的重金属含量显著相关（P<0.01，P<0.05），可以作为Cu、Cr、Ni的良好指示生物。

The concentrations of heavy metals in benthos ( aquatic oligochaetes ) is remarkably correlated with that in sediments ( P < 0.01 , P < 0.05 ), so the former can be used as bio indicator of Ni , Cu and Cr.

共发现轮虫28种，甲壳类8种，还发现寡毛类、线虫、摇蚊幼虫、水螨等种类。

Other species including oligochaeta , nematode , chironomus and water mites were also recorded .

现阶段国内外利用微型动物进行污泥减量的研究主要集中在寡毛类蠕虫如仙女虫、红斑顠体虫、颤蚓等体型较大的后生动物。

Domestic sludge reduction research using micro-stage animals are mainly focused on oligochaetes worms , such as Naididae , Aeolosma hemprichii , Tubificidae and other large size metazoanes .

对比历史数据可知，洱海寡毛类和摇蚊科比例继续增加，表明湖泊有机污染进一步加重。

Compared with historical data , the proportions of Oligochaete and Chironomid in Erhai Lake continued to increase , which implied that the organic pollution in the Lake was further intensified .

西湖和青山水库底栖动物群落主要由寡毛类和摇蚊幼虫组成，存在适应低溶氧、耐有机污染的种群。

In these two sites , the benthic animal community were mainly composed of oligochaeta and chironmus larva , they were adaptive to low concentration DO and were resistive to organic pollution .
