二叠纪节房虫类高阶分类现状、过去和未来
Higher Taxonomy of Permian Nodosarioids: Present, Past and Future

二叠纪节房虫类有孔虫形态学高阶分类现状表明，苏联和美国两个学派的高阶分类特征存在尖锐对立.追溯两个学派高阶分类特征的历史渊源后，评述了当前有孔虫的高阶形态学分类.美国学派的高阶分类特征源自19世纪中晚期的英国学者；苏联学派的高阶分类特征则是进化分类方法应用的自然结果.苏联学派将系统发育贯彻始终，较美国学派更符合逻辑，但其系统发育重建缺乏科学性.通过结合形态、分支系统和分子系统发生等方法，有望解决二叠纪节房虫类的高阶分类问题.
Present status of higher taxonomy based on morphology shows that the American school differs from the Soviet school on major taxonomic characters. Historical origin of higher taxonomic characters of the two schools are tracked and the present foraminiferal morphological classifications are reviewed. The results show that the higher taxonomic characters of the American school derive from the English workers in the midlate nineteenth century, whereas the characters of the Soviet school are natural results of the application of evolutionary taxonomic methods. The Soviet school applies phylogeny systematically, therefore the higher classifications of which are more soundly based than that of the American school. However, reconstruction of phylogeny of the Soviet school is not scientifically based. Problems in higher taxonomy of Permian nodosarioids will possibly be solved when combining morphological study with molecular phylogenetic and cladistic studies
