摘要/Abstract

摘要： 群落多样性的维持机制是群落生态学研究的热点问题.尾矿库作为人工原生裸地,土壤重金属含量较高,随着恢复年限的延长,土壤理化性质发生变化,是研究土壤微生物群落多样性驱动机制的理想场地.本研究在调查十八河尾矿库土壤因子、植物群落多样性和土壤细菌群落多样性的基础上,探究了局域小尺度下细菌群落结构和多样性的驱动机制.结果表明: 尾矿库土壤养分含量随恢复年限的延长显著提高,并具有一定的季节变化,不同恢复年限土壤养分含量的季节动态存在差异.细菌群落的Shannon多样性和丰富度指数随恢复年限呈显著增加趋势,群落稳定性逐步提高;而其季节变化受到植物群落的影响,在不同恢复年限下具有一定的差异.RDA分析显示,环境因子对土壤细菌群落多样性有决定作用.结构方程模型分析表明,土壤养分(TC、TN、NO₃^--N、NO₂^--N)含量、植物群落多样性和土壤酶活性共同驱动该铜尾矿库土壤细菌群落的构建过程.

Abstract: The maintaining mechanism of community diversity is the core of community ecology. The mine tailing is a good field for studying on the underlying mechanism of community diversity, as a kind of original bare land with heavy metal pollution, where the physicochemical characteristics of soil change with the restoration periods. We examined the driving forces for bacterial community diversity based on the investigation of edaphic factors, plant community, and bacterial communities in Shibahe copper mine tailing, Shanxi. The results showed that nutrient contents in soil increased with restoration periods. The seasonal dynamics of soil nutrient in different restoration time were different. Shannon diversity and richness of bacterial community showed an increasing trend, indicating community stability was improved with restoration. Influenced by plant community, the seasonal changes of those indices differed with restoration. Results from the RDA analysis showed that the diversity and structure of bacterial communities were determined by environmental factors (edaphic, plant and heavy metals). Results from the structure equation models further confirmed that soil nutrients (TC, TN, NO₃^--N, NO₂-N), plant community, and soil enzyme activities jointly drove bacterial community assembly on the copper mine tailings.
