[Response of Soil Archaeal Community to Heavy Metal Pollution in Different Typical Regions].
摘要
<0.05), making them the main driving factors of archaeal community structure. The null-model analysis showed that the assembly process of the archaeal community was mainly influenced by heterogeneous processes, including heterogeneous selection (deterministic process) and dispersal limitation (stochastic process). Heterogeneous selection played a vital role in our study areas, while homogeneous selection only occurred in samples around the metal enterprises. Therefore, environmental selection was the ultimate driver of the archaeal community assembly process in this study, and its relative importance varied according to habitat type. Environmental heterogeneity increased the contribution of heterogeneous selection to community assembly, thus enhancing the community's resistance to environmental stress, and contributing to the stability and sustainability of the agricultural ecosystem.
