The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.
对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析,结果支持原目、愈腹目的单系性,长角目不形成单系群,支持短角科从愈腹目中分出,但鳞总科和短角目的分类地位有待于深入分析探讨;进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列,以1种多足动物和1种螯肢动物为外群,进行系统关系分析,结果显示:原尾纲、弹尾纲、双尾纲分别为单系群,原尾纲和双尾纲优先聚为一支,然后和弹尾纲构成姐妹群,以上三类又和昆虫聚为一支,支持六足动物的单系性,支持泛甲壳动物,但甲壳动物并未形成单系,其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

Combined with additional sequences of 20 bivalves and 6 gastropods downloaded from NCBI (National Center of Biological Institution), molecular phylogenetic trees were constructed using 4 Polyplacophora species as outgroup. The result resolved by maximum-parsimony, maximum-likelihood and Bayes-induce methods were in congruent with each other, which indicated that all bivalves formed a monophyletic group clustering with its sister-group, Gastropod.
结果显示:所有双壳纲的种类构成了单系发生的进化枝,与其姐妹群腹足纲聚在一起;双壳纲可以分为异齿亚纲和翼形亚纲两大类群,异齿亚纲是单系发生,翼形亚纲的系统发生关系则随方法的不同有所区别,牡蛎科的位置是造成此差异的主要因素。

This thesis set up the pedogenetic classification system of the sub-Antarctic maritime climate region, and the soils of study area are classified into 3 orders. 4 suborders (cryentisolorder、cryaquept-order, cryochrept-order and cryohistosol-order) and 13 groups. The diagnostic soil characteristics of each group are analysed. The soil mapof Fildes Peninsula of King George Island. Antarctica (1∶20000) is mapped.

suborder:亚纲
2.亚纲(suborder) 主要根据土壤水热状况、土层特征、土壤矿物质组成和风化程度等划分. 各土纲的亚纲划分多是选择各土纲本身的一些重大变异特征(即对土壤发生和植物生长来说堪称为重大的),作为划分亚纲的依据. 各土纲的亚纲及主要特征见表3-6.
