摘　　要：本文介绍了蕨类植物化石原位繁殖器官微细构造研究的实验技术和方法，讨论了这一研究在蕨类植物化石的分类归属和系统演化研究中的意义．The authors brifely introduce the technique of study on reproductive structures of fossil ferns, which inelude sorus, indusium, sporangium, annulus,spore output and spore.The taxonomic, identified and evolutionary significances of them are systematically discussed. As examples, some reproductive organs of the Early Cretaceous ferns from Northeast China: Ruffordia, Athyrium, Dryopterites, Acanthopteris, Coniopteris, Dicksonia and Arctopteris are shown in the plate.
