摘　　要：车轮虫是一类水产养殖中常见的寄生原虫。本研究采用国际间车轮虫的现代形态学研究方法,对单型车轮虫(Trichodina uniforma Van As&Basson,1989)的13个种群进行了种群间比较研究,结果表明:单型车轮虫虽然主要寄生于鲤科鱼类,但不具寄主专一性和寄生部位的专一性特点,瓦氏黄颡鱼(Pelteobagrus vachelli)是单型车轮虫的新发现宿主;本工作首次应用SPSS软件对单型车轮虫的两种群进行了形态性状差异显著性检验,结果显示单型车轮虫的种群间不存在显著性差异。SPSS统计方法不仅可解决分类学中的部分存疑,同时也为车轮虫的种间分析或种群间的差异性研究提供了一种新思路与新方法。Combined with the use of Excel and SPSS softwares, the population comparative research of Trichodina uniforrna Van As Basson, 1989 was implemented following the widespread acceptance of the uniform specific characteristics proposed by Lom （1958） and the description of denticle elements recommended by Van As ＆ Basson （1989） in the present work. The result indicates that Trichodina uniforrna was mainly parasitic on Cyprinidae fishes; however, it is a widespread distributed ectoparasite without specifity of host and location. The SPSS software was first used for the different population significance testing and no significant differences existed in the different populations for Trichodina uniforma in the present work, which supported the morphological i- dentification. Pelteobagrus vachelli was established as the new host record for Trichodina uniforma. The SPSS statistics method can not only solve part problems in taxonomy, but also provide a new idea and method for the diversity research for intra-populations or species of trichodinids.
