Soil microbial functional diversity responses to different vegetation types in the Heilongjiang Zhongyangzhan Black-billed Capercaillie Nature Reserve

Abstract Purpose The soil microbial community is an important bioactive component of terrestrial ecosystems. Its structural and functional diversity directly affects carbon nitrogen processes. This study aimed to investigate the variations in communities forests with different types vegetation. Methods We selected three typical vegetation types, larch (LG), black birch (BD), mixed (LGBD) forests, located Heilongjiang Zhongyangzhan Black-billed Capercaillie Nature Reserve. Biolog-Eco microplate technology was perform these analyses. Result Our results showed clear differences between microorganisms forests. average well colour development (AWCD) change rate gradually increased incubation time. BD type had highest AWCD value, followed by LGBD; LG forest lowest value. difference alpha index significant. A principal analysis that PC1 PC2 respectively explained 62.77% 13.3% variance observed. carbon-source utilisation patterns under were mainly caused esters carbohydrates. Redundancy strongly affected physicochemistrical properties (e.g. organic carbon, total pH). Conclusion These provide a reference for further exploring relationship microbes during process succession.
