摘　　要：自由生活海洋线虫是海洋中最丰富的后生动物 ,它属于小型底栖动物的永久性成员 ,即分选时 ,可通过 0 .5 mm或 1 mm网筛但被 0 .0 31 mm或 0 .0 4 2 mm孔径网筛蓄留的动物 ,本文讨论线虫在动物界的分类地位 ,与相近动物类群的亲缘关系 ,泄腺纲与泄管纲分类系统的由来和演变。海洋线虫属于泄腺纲 ,由 Bremerhaven种名录和 L orenzen确立的分类系统已得到广泛的应用。海洋线虫的分类系统仍处在发展和完善中 。Free living marine nematodes are the most abundant metazoans in marine sediments and also the dominant permenent member of the meiofauna that has been defined as organisms capable of passing through a sieve with an aperture 0.5 mm (1 000μm) but retained by a sieve with an aperture 0.042 mm (0.031mm) . This paper describes the phylogenetic position for nematodes in invertebrates and their relationship with close groups. That marine nematodes are of a the phylum and division of adenophorea and secernentea has been accepted by most nematologists. The systematic system established by Gerlach and Riemann's, Bremerhaven Checklist and Lorenzen, has been recognized by most marine nematologists. The systematics of marine nematodes is still under development. It is ncessary to discover more characters of synapomorphy for the identification of species and higher taxa.
