吉林省山地河流毛翅目幼虫的分布及对水质监测和评价的研究

Studies on distribution of caddis larvae and bioassessment of water quality for mountain rivers in Jilin province

本文报道了吉林省东南部山地主要江河上游毛翅目幼虫的分布状况，计１２科１９属３１种。并结合水质理化监测数据，对浑江六个断面的水质进行综合评价，探讨毛翅目幼虫对水质的指示作用，确定旋刺纹石蚕为弱──强中污带水体的指示生物。

This paper reports species distribution of caddis larvae in the upper reaches of main rivers in southeast mountainous region of Jinn province. 31 species were founded belong to 12 families,19 genera.cambining they with data of water quality physics and chemistry monitoring,to overall assessing water quality state for 6 sections in Hun River.And to.indicating action for water quality were explored by using materials of caddis larvae in water.Determing the Hydropsyche(Ceratopsyche)nevae Kolenati is an indicator organism for 5 a mesosaprobic zone of polluted rivers.
