| 摘 要： | 微生物是土壤元素生物地球化学循环的主要驱动力,目前库滨带植物截留和消减污染物质过程中细菌群落及其功能研究尚未清楚.本研究选取适宜丹江口库区库滨带生长的4种典型植物(草本植物香根草、芦苇、乔木植物杜梨和灌木植物假奓包叶),采用16S r DNA Miseq高通量测序技术研究根际细菌群落组成,发现其主要由变形菌门、拟杆菌门、放线菌门等31个门、343个属的细菌组成,表现出群落组成的丰富性.细菌群落分析表明香根草和芦苇细菌群落结构较为相似,但和杜梨细菌群落结构差异最大.PICRUSt功能预测分析表明,库滨带植物根际细菌主要涉及次生产物代谢的生物合成、转录、多糖生物合成和代谢、细胞生长和死亡等38个子功能,表现出功能上的丰富性.库滨带植物根际细菌代谢能力整体趋势为假奓包叶芦苇香根草杜梨.本研究初步探讨了丹江口库区库滨带不同植物根际细菌群落和功能,为丹江口水库库滨带植被构建及其水环境保护提供了参考依据.
