Abstract
Soil microorganism play an important role in maintaining the structure and function in warm temperate forest ecosystem. In order to explore the characteristics of soil microbial community under different stand types in in warm temperate zone, Illunima Miseq High-throughput Sequencing was used to assess the soil bacteria (16S rRNA) and fungi (ITS rRNA) communities of five forest stands (Pinus tabulaeformis [PT], Juglans mandshurica [JM], Betula platyphylla [BP], Betula dahurica [BD] and Quercus mongolica [QM]) in Songshan Nature Reserve. The results showed that the bacterial diversity under Juglans mandshurica forest was higher than other types, the fungal diversity under Pinus tabulaeformis forest was higher than other types. The dominant phyla and gene of soil bacteria were similar in different stand types, but there were significant differences in abundance and dominant gene of fungal community. VPA analysis showed that soil explained 49.1% of the variance in bacterial community composition and 70.6% of the variance in fungal community composition. RDA analysis showed that the dominant phyla were significantly correlated with soil pH, SOM, TN and AN. Based on our results, there are significant differences in soil microbial community structure among different stand types. Consequently, our results have important implications for understanding the driving mechanisms that control the soil microbial community during warm temperate forest.
