摘要： 在城市森林生态系统中，台风过后产生大量绿色凋落物常堆积于草坪与土壤表面。由于微环境和土壤动物可获取性的不同，不同位置凋落物分解过程中的碳和养分循环可能存在差异。然而，目前少有研究关注台风产生的绿色凋落物与生理性衰老形成的凋落物在不同微生境中的分解差异。针对这一问题，本研究以香樟(Cinnamomum camphora)为研究对象，在草坪上和土壤表面同步开展绿色凋落叶和衰老凋落叶分解实验。结果表明：1)草坪上绿色和衰老凋落叶剩余质量均显著低于土壤表面，两类微生境中衰老凋落叶剩余质量均显著高于绿色凋落叶。2)草坪上衰老和绿色凋落叶碳残留量均显著低于土壤表面，绿色凋落叶碳氮残留量均显著低于生理性凋落叶。春季凋落高峰后，土壤表面绿色凋落叶的碳氮磷残留量显著下降。3)土壤动物显著降低了凋落叶剩余质量及碳磷残留量，其对绿色凋落叶分解的影响强于衰老凋落叶的分解。上述结果说明，绿色和衰老凋落叶在不同微生境中表现出明显不同的分解模式。
