运用地理统计学和Illumina 16S rRNA基因测序等手段,研究广西环江木论国家自然保护区25 hm~2喀斯特常绿落叶阔叶林土壤主要门级微生物类群的空间分布。结果表明:广西环江木论国家自然保护区喀斯特森林土壤中优势菌门为变形菌门(Protebacteria,34.5%)、放线菌门(Actinobacteria,30.7%)和酸杆菌门(Acidobacteria, 12.2%);土壤细菌类群显示空间相关性的自相关范围为44.4~841.4 m,其中大部分细菌类群的变程在研究区域范围(500 m)内;在研究区内,变形菌门的相对丰度从北到南逐渐升高,而放线菌门和厚壁菌门(Firmicutes)的相对丰度则从北到南逐渐降低,绿弯菌门(Chloroflexi)、酸杆菌门、奇古菌门(Thauma...

To understand the spatial pattern of soil microbial communities at the phyla level in Mulun National Natural Reserve in Huangjiang of Guangxi, we used geostatistical modeling and Illumina sequencing of 16S rRNA genes to the soils in a 25 hm~2 karst evergreen deciduous broadleaf forest. The results showed that the dominant bacterial phyla in the karst forest soils were Protebacteria(34.5%), Actinobacteria(30.7%) and Acidobacteria(12.2%). Soil bacterial taxa showed spatial dependence with an autocorrelation range of 44.4-841.4 m, and most of them were within the scope of the study plot(500 m). A...
