The knowledge concerning the relationship between vegetation restoration and soil microorganisms is limited, especially at high altitudes. In order to evaluate the restoration efficacy of the reforestation on the soil microbial community, we have examined vegetation composition, edaphic properties and structure and function of different soil microbial groups in two different aged (25- and 40-year-old) var. Rehder & E. H. Wilson (. ) plantations and the primeval coniferous forest (PCF) dominated by Masters by plot-level inventories and sampling in western Sichuan Province, China. Our results suggested that only the fungal samples in 25-year-old . plantation could be distinguished from those in the PCF in both structure and function. The structure and function of the fungal community recovered relatively slowly compared with bacterial and archaeal communities. In addition to the soil chemical properties and tree species composition, the shrub composition was also a key factor influencing the soil microbial community. The plantations were conducive to restoring the soil microbial community in both structure and function. However, there were uncertainties in the variations of the bacterial and archaeal communities with increasing the . plantation age.
关于植被恢复与土壤微生物之间关系的知识有限，尤其是在高海拔地区。为了评估造林对土壤微生物群落的恢复效果，我们通过样地调查和采样，研究了中国四川省西部两种不同树龄（25年和40年）的岷江冷杉人工林以及以麦吊云杉为主的原始针叶林中的植被组成、土壤性质以及不同土壤微生物类群的结构和功能。我们的结果表明，只有25年生岷江冷杉人工林中的真菌样本在结构和功能上能够与原始针叶林中的真菌样本区分开来。与细菌和古菌群落相比，真菌群落的结构和功能恢复相对较慢。除了土壤化学性质和树种组成外，灌木组成也是影响土壤微生物群落的关键因素。岷江冷杉人工林有利于土壤微生物群落结构和功能的恢复。然而，随着岷江冷杉人工林树龄的增加，细菌和古菌群落的变化存在不确定性。
