探究土壤微生物的海拔分布格局及其驱动机制对理解气候变化下陆地生态系统的响应至关重要.土壤微生物群落的海拔分布格局随空间尺度有所差异,为此分别沿大通河流域干流流向(海拔梯度1 000 m)和山体坡面(海拔梯度500 m)设置了两种空间尺度的样带,利用高通量测序技术分析土壤细菌群落结构和多样性沿海拔的分布特征,基于FAPROTAX数据库分析氮循环功能类群的海拔分布,探讨驱动土壤细菌群落沿海拔分布的关键环境因子.结果表明:①土壤理化性质沿海拔分布有显著差异,总氮(TN)和硝态氮(NO_(3)-)含量与海拔正相关(Ph.海拔负相关(P0.05);③细菌群落以酸杆菌门(Acidobacteria)、变形菌门(Proteobacteria)和拟杆菌门(Bacteroidetes)为优势门,其相对丰度随海拔升高分别增加、减小和微弱减小;④参与氮循环的功能类群共13种,以硝化作用、好氧氨氧化和好氧亚硝酸盐氧化作用为主,随海拔升高响应规律不同,其中硝化作用细菌丰度显著增加(Ph.氨氮(Nh.+)是驱动门水平土壤细菌群落的主要因子,Mantel分析表明土壤细菌氮循环优势类群均受海拔驱动(P<0.01).⑥流域和坡面尺度上细菌群落α-多样性沿海拔的规律一致,但土壤性质、氮循环功能菌群丰度和主要环境影响因子均不同.因此从不同空间尺度探究土壤微生物的海拔分布格局具有重要意义.
