The relationships among the five families are very close, so we support the view that these five families can be combined into one family Acrididae.(3) It is suggested that Arcypterinae, Gomphoceridae and Chrysochraontinae be combined into Gomphocerinae of the family Acrididae.

The monophyly of Colelmbola is widely accepted. However, the controversies about the system and the phylogeny of it are existent between different taxonomists. Questions such as whether the Collembola aquatic and which relationships between the different groups in Collembola are argued, too.

跳虫的单系性已经被广泛接受，但是不同的分类学家对跳虫的分类系统和系统发生持有不同的看法，对于跳虫的水生还是陆生的起源，跳虫内部各个类群之间的亲缘关系等问题，一直具有争议。

According to the neighbor-joining tree on 75 leaf cuticle, architecture, flower and fruit characters, the traditional taxonomic system based only on reproductive characters shows some degree of irrationality. 4. Comparative embryology The developmental process of flower and fruit production was studied for the first time in Castanopsis delavayi and compared with other taxa of Fagaceae.

根据叶结构、叶表皮、果实和壳斗等在内的75个特征所建立的邻接树的分支情况大体上和壳斗科根据花、壳斗特征建立的分类系统基本一致，但是有存在不一致的情况，仅仅根据花、壳斗特征建立的分类系统具有一定的不合理性。

Nowadays, the nomenclature and taxonomy based on Linnaean system, though has a history of over 250 years, are still predominant among taxonomists, and the following international nomenclature codes of zoology, botany and bacteria have run its way for about 100 years and are keeping on revising.

基于林奈命名法和林奈分类系统的生物分类系统已经存在250多年并仍然为广大生物学工作者使用，由此产生的国际动物、植物、细菌的命名法规亦执行了100年（1905年，国际植物命名法规第1版产生），并在不断修订。

Mathematical structure of biological classification and its convincing interpretation have been an academic issue that has aroused extensive attention in the biological circle, but few have applied statistical distribution models to the study or analysis of structure of nonbiological classification, such as Soil Taxonomy.

生物系统分类的数学结构及其令人信服的解释一直以来是生物学界广泛关注的经典学术问题，然而很少有人用统计分布模型对非生物分类系统的结构进行分析与研究。

A total of 139 species in 40 genera are recognized in the Chinese pterophorid fauna at present,of which 18 species are described as new to science.

本项目首次对我国的羽蛾科昆虫区系进行全面、系统的整理和种类订正；查清我国羽蛾科昆虫目前共有40属139种，发表新种18个，并阐明它们在地理分布上的规律和特点；澄清分类疑点，完善分类系统；建立我国羽蛾科昆虫区系资料库。

Based on the references concerned to Schisandraceae, several taxonomical problems, such as systematical position of Schisandraceae, relationship between Schisandra and Kadsura, and their system were discussed.

基于近年来的研究成果，对五味子科的分类地位和系统关系、五味子属和南五味子属之间的关系及其分类系统等问题进行了讨论。
