摘要: 土壤"慢"有机碳库介于"活性"和"惰性"库之间,是植物残体迅速损失的一个重要中间分解阶段.本文主要综述了代表很大比例土壤"慢"有机碳库的微粒有机质(POM)的表征、意义,及影响土壤"慢"有机碳库中POM周转的主要因素,POM在土壤团聚体中和土壤剖面中的分布以及动态变化.

Abstract: Slow" soil organic carbon pool which intervenes between "active" and "inertia" pool,is an important middle decomposing stage of rapid litter loss. This paper summarized characteristics and significance of particulate organic matter(POM), which represented a high proportion of "slow" soil organic carbon pool, primary factors of the influencing POM turnover, and distribution and dynamic change of POM in aggregates and soil profile.
