摘要:
森林土壤微生物群落作为分解者、共生体或病原体,在调节生物地球化学循环方面起到关键作用。土壤细菌能够释放土壤无机物、矿石或有机质中的营养元素,在森林生态系统的养分循环中起着重要作用。该研究以扬州市茱萸湾风景区内6种不同植被类型的城市森林作为研究对象,对不同植被类型下土壤细菌群落结构及多样性指数进行比较研究。结果表明,水杉林土壤细菌的物种总数、菌群丰度和复杂度最高,其次是竹林和山茱萸林。水杉林的土壤细菌群落的均匀度最高,其次是竹林和杂阔林。山茱萸林独有的土壤细菌的OTUs数目最多,与其他森林群落土壤细菌的OTUs分布差异较大;在门分类水平上,该地区相对丰度平均值大于1%的优势菌门有11个。
Abstract:
Forest soil microbial communities, as decomposers, symbionts or pathogens, play a key role in regulating biogeochemical cycles. Soil bacteria can release nutrients in soil inorganic matter, ore or organic matter, and play an important role in nutrient cycling of forest ecosystem. In this study, six urban forests in Zhuyuwan Scenic Area of Yangzhou City were taken as the research objects to compare the soil bacterial community structure and diversity index under different vegetation types. The results showed that the total number, abundance and complexity of soil bacteria in Metasequoia glyptostroboides forest were the highest, followed by Phyllostachys pubescens forest and Cornus officinalis Sieb forest. The soil bacterial community uniformity of Metasequoia glyptostroboides forest was the highest, followed by Phyllostachys pubescens forest and mixed broadleaf forest. The number of OTUs of soil bacteria unique to Cornus officinarum was the highest, and the distribution of OTUs was different from that of soil bacteria in the other forest communities. At the taxonomic level of phyla, there were 11 dominant phyla with average relative abundance greater than 1% in this region.
