微生物不仅使土壤有机质的分解和合成处于相对平衡状态，而且可矿化有机物提高土壤肥力。

Soil microbes can not only sustain the balance of decomposition and composition of soil organic matters, but also improve soil fertility by mineralizing the organic matters.

凋落物分解是森林生态系统养分循环中的重要过程，对土壤有机质的形成和养分释放有重要意义。

Forest litters decomposition was an important process of nutrient cycling in forest ecosystems, and played a central role in soil organic matter formation and nutrients release.
