本文根据经过成虫形态特征的主成分分析与聚类分析后确认具有种独立地位的7种并殖吸虫的7项成虫形态特征,在电子计算机上,采用关系数据库dBASEⅡ,对我国10省、地区的并殖吸上进行检索,结果表明:广东(梅县)、湖南、河南、四川、陕西的吸虫同为斯氏狸殖,但各居群均有一定的形态差别。远离模式产地广东省的河南、四川与陕西差别似较大。广东(梅县)、江西、浙江、安徽、吉林的并殖吸虫同为卫氏并殖,这5个居群的吸虫也存在差別,其差别主要在于虫体长宽比例。
Based on the morphological characteristics of the adult morphological characteristics of the principal component analysis and clustering analysis to confirm the species independent status of seven species of Paragonimus adult morphological characteristics of the electronic computer, using the relational database dBASE Ⅱ, 10 provinces and regions in our country The results showed that the flukes in Guangdong (Meixian), Hunan, Henan, Sichuan and Shaanxi belonged to the same genus Trichogramma, but all the populations had some morphological differences. Far away from the mode of origin of Henan Province in Henan Province, Sichuan and Shaanxi differences seem larger. Paragonimus in Guangdong (Meixian), Jiangxi, Zhejiang, Anhui, and Jilin are the same as Watson, and there are differences in the flukes among the five populations. The difference lies mainly in the aspect ratio of parasites.
