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。

The kinetics of degradation of healthy paddyfield ecosystem due to unreasonable fertilization are as follows.(1) The rice growth was interfered and the structure of microbe population was altered through applying excessive nitrogen fertilizer, while the yield of rice was decreased later and the secretion was reduced from rice root, which induced the Eh and the quantities of Bacterium and Actinomycetes declining, and the contents of MBC, MBN, MBP low in the soil. All of that made the capacity of accommodating nutrient weak in microbe ecosystem.

不合理施肥引起的稻田生态系统退化的动力学特征是：(1)重施氮肥首先使水稻植株生长受阻，同时改变土壤微生物种群结构，从而直接使水稻产量降低，稻田土壤生产力受损，并产生一系列不良次级反应：水稻生理活动减弱减少了根系分泌量，同时也降低了土壤Eh，使稻田土壤细菌、放线菌数量降低，MBC、MBN以及MBP含量下降，微生物保肥、供肥能力降低，从而土壤微生物生态系统功能弱化。
