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

黑龙江中羊站黑嘴鹬自然保护区土壤微生物功能多样性对不同植被类型的响应

土壤微生物群落是陆地生态系统的重要生物活性成分。其结构和功能的多样性直接影响碳和氮过程。本研究旨在探讨不同植被类型森林土壤微生物群落功能多样性的变化。我们选择了落叶松(LG)、黑桦(BD)和落叶松与黑桦混交(LGBD)三种典型植被类型,位于黑龙江省中羊站黑嘴鹬类自然保护区。选择 Biolog-Eco 微孔板技术进行这些分析。我们的研究结果表明,三个典型森林中的微生物之间存在明显差异。平均孔显色 (AWCD) 变化率随着孵育时间逐渐增加。BD 型的 AWCD 值最高,其次是 LGBD;LG 森林类型的值最低。BD和LG土壤微生物α多样性指数差异显着。主成分分析表明 PC1 和 PC2 分别解释了观察到的方差的 62.77% 和 13.3%。不同植被类型下土壤微生物碳源利用模式的差异主要是由酯类和碳水化合物引起的。冗余分析表明,土壤微生物功能多样性受土壤理化性质(如有机碳、总氮和pH值)的强烈影响。这些结果为进一步探讨森林演替过程中森林群落与土壤微生物的关系提供了参考。BD和LG土壤微生物α多样性指数差异显着。主成分分析表明 PC1 和 PC2 分别解释了观察到的方差的 62.77% 和 13.3%。不同植被类型下土壤微生物碳源利用模式的差异主要是由酯类和碳水化合物引起的。冗余分析表明土壤微生物功能多样性受土壤理化性质(如有机碳、总氮和pH)的强烈影响。这些结果为进一步探讨森林演替过程中森林群落与土壤微生物的关系提供了参考。BD和LG土壤微生物α多样性指数差异显着。主成分分析表明 PC1 和 PC2 分别解释了观察到的方差的 62.77% 和 13.3%。不同植被类型下土壤微生物碳源利用模式的差异主要是由酯类和碳水化合物引起的。冗余分析表明土壤微生物功能多样性受土壤理化性质(如有机碳、总氮和pH)的强烈影响。这些结果为进一步探讨森林演替过程中森林群落与土壤微生物的关系提供了参考。不同植被类型下土壤微生物碳源利用模式的差异主要是由酯类和碳水化合物引起的。冗余分析表明土壤微生物功能多样性受土壤理化性质(如有机碳、总氮和pH)的强烈影响。这些结果为进一步探讨森林演替过程中森林群落与土壤微生物的关系提供了参考。不同植被类型下土壤微生物碳源利用模式的差异主要是由酯类和碳水化合物引起的。冗余分析表明,土壤微生物功能多样性受土壤理化性质(如有机碳、总氮和pH值)的强烈影响。这些结果为进一步探讨森林演替过程中森林群落与土壤微生物的关系提供了参考。
