对脉冲释放养分的重要性的关注主要集中在热带森林生态系统上。有机质的突然添加、附生植物的淋溶或微生物生物量的裂解都可能导致脉冲营养矿化。湿和干循环可以极大地影响碎屑食物链，导致营养矿化的脉冲，但脉冲和稳定系统之间的差异并不总是被认识到。在一种或多种矿物元素限制植物和微生物分解者生长的情况下(在某些热带森林和一些温带生态系统中发现这种情况)，脉冲营养矿化可能特别重要。烘干-
A ttention to the signifi-cance of pulsed nutrient release has focused re-, cently on tropical forest ecosystems. Pulsed nutrient mineralization can result from sudden additions of organic matter, leaching from epiphytes, or lysis of microbial biomass. Wetting and drying cycles can dramatically affect detrital food chains leading to pulses of nutrient mineralization, but the differences between pulsed and steady-state systems has not always been appreciated’. Where one or more mineral elements are limiting to the growth of plants and microbial decomposers (a condition found in certain tropical forests as well as some temperate ecosystems), pulsed nutrient mineralization may be particularly important. Drying-
