A clone from each genotype was randomly selected as representative for sequencing. The obtained 16S rDNA gene sequences had a similarity of 87%-100% with those in the GenBank (www. ncbi. nlm. nih. gov), and more than half of them had a similarity lower than 97%, being of new species. Based on phylogenetic analysis, the bacteria in the two soils were classified into 10 groups, with 5 groups in common. The dominant bacterial groups in the two soils differed obviously. In primeval forest soil, the dominant group was Proteobacteria, which had 39 genotypes, occupying 58.0% of all the clones; while in the soil of degraded ecosystem the dominant groups were Acidobacteria and Proteobacteria, which had 19 and 15 genotypes occupying 32.5% and 30.5% of all the clones, respectively. In the soil of degraded ecosystem, Proteobacteria group decreased while Acidobacteria group increased markedly, compared with those in primeval forest soil.

从每种基因型中随机选择一个克隆子作为代表进行测序分析，所有序列与GenBank数据库中序列的同源性为87%~100%，且两样地中均有超过一半的基因型序列与数据库中已知序列同源性低于97%，属于分类在"种"地位上的新发现细菌；通过系统发育研究将两样地的细菌分为10大类群，两样地共同拥有5大类群，但两样地的细菌优势类群明显不同，原生土壤为Proteobacteria，含39种基因型，占总克隆子数的58.0%，退化生态系统土壤为Acidobacteria和Proteobacteria，分别含19种和15种基因型，占总克隆子数的32.5%和30.5%；与原生土壤细菌类群相比，退化生态系统土壤Proteobacteria类群明显减少，Acidobacteria类群明显增加。

In recent years, as methods of the molecular phylogeny widely used in the studies of systematics and phylogeny of Nymphalidae, the basic phylogenetic patterns of them have been clarified. However, up to the present, these studies, especially about the taxa distributed in China is rather scarce.

近年来，由于分子生物学在蛱蝶科系统分类中的广泛应用，蛱蝶科各主要类群间系统发生关系的格局逐步清晰，但国内蛱蝶科的分子系统学研究还十分匮乏。

This paper also brings forward the strategic target of planning and designing the green system in this region to provide reference and guidance for planning work. Based on GIS, this paper analyzes landscape spatial pattern, dynamic pattern and landscape functional division. And it holds out the planning project to major the structure of green system in the research zone. And that is the core content in this research. There is peculiar sense to represent and extend the psammophyte garden in justifying the agriculture framework in the research zone. So this paper takes the psammophyte garden as a concrete unit to proceed landscape eco-designing.
