- Natural forest succession after disturbances is one of the most important restoration strategies. However, the responses of ecosystem multifunctionality during natural forest succession remains poorly understood in forest ecosystem.
- Here we evaluated how the ecosystem multifunctionality including nutrient cycling, carbon stocks, water regulation, decomposition, wood production and symbiosis develops using a chronosequence, and identified the key factors contributing to the variations in the ecosystem multifunctionality during natural forest succession.
- We provide evidence that the ecosystem multifunctionality gradually increased along with succession stages. The individual functions of carbon stocks and water regulation also exhibited increasing patterns with stand development. The microbial diversity were more principal factors than plant diversity and soil properties for the explanation of changes in the ecosystem multifunctionality. The regression analysis showed that the diversity of bacteria, general fungi, actinomycetes, nematodes, G+ bacteria and G− bacteria significantly and positively associated with ecosystem multifunctionality. Soil nematodes exhibited significantly positive correlation with most of the individual functions.
- Synthesis and applications. Taken together, our results demonstrate that natural forest restoration plays a key role in promoting ecosystem multifunctionality, and emphasize the importance of soil microbial diversity for the maintenance of ecosystem functions and health.

微生物多样性在自然次生演替过程中调节生态系统的多功能性
- 干扰后的天然林演替是最重要的恢复策略之一。然而，森林生态系统对天然林演替过程中生态系统多功能性的响应仍知之甚少。
- 在这里，我们使用时间序列评估了包括养分循环、碳储量、水分调节、分解、木材生产和共生在内的生态系统多功能性如何发展，并确定了导致天然林演替过程中生态系统多功能性变化的关键因素。
- 我们提供的证据表明生态系统的多功能性随着演替阶段而逐渐增加。碳储量和水调节的个别功能也随着林分的发展呈现出增加的格局。微生物多样性是比植物多样性和土壤性质更能解释生态系统多功能变化的主要因素。回归分析表明，细菌，一般霉菌，放线菌，线虫的多样性，G +菌和G -菌显著和正与生态系统的多功能性相关联。土壤线虫与大多数个体功能呈显着正相关。
- 合成与应用。综上所述，我们的研究结果表明，天然林恢复在促进生态系统多功能方面发挥着关键作用，并强调了土壤微生物多样性对维持生态系统功能和健康的重要性。
