草坪上和土壤表面的台风产生的凋落物呈现出不同的分解模式

Abstract

Abstract: Typhoon-generated green litter is commonly deposited on lawns and soil surfaces in urban forest ecosystems, where differences in microenvironmental conditions and soil fauna accessibility may alter the pathways of carbon (C) and nutrient cycling during litter decomposition. However, knowledge regarding the decomposition of typhoon-generated green litter and physiologically senesced litter in these microhabitats remains limited. To address this gap, we simultaneously incubated typhoon-generated green and naturally senesced leaf litter of camphor (Cinnamomum camphora) tree on the lawn and soil surfaces in combination with soil fauna exclusion. The mass remaining of senesced and green litter was significantly lower on lawns than on soil, and the mass remaining of senesced litter was significantly higher than that of green litter in both microhabitats. Carbon remaining in senesced and green litter on the lawn was markedly lower than those on the soil surface. Additionally, C and nitrogen (N) remaining in green litter were substantially lower than those in senesced litter. A notable decrease in C, N, and phosphorus (P) remaining in green litter on the soil surface occurred after the spring litter peak. Furthermore, soil fauna significantly reduced litter mass remaining, as well as C and P remaining, exerting a stronger effect on the decomposition of green litter than on senesced litter. We conclude that green and senesced litter exhibit distinct decomposition patterns across microhabitats.

摘要：
城市森林生态系统中，台风产生的绿色凋落物普遍堆积于草坪上与土壤表面，其微环境条件和土壤动物可达性的差异可能改变凋落物分解过程中的碳和养分循环途径。然而，目前有关台风导致的绿色凋落物与自然衰老形成的生理性凋落物在这些不同微生境中的分解研究相对有限。为了解决这一问题，我们结合土壤动物排除法，将台风产生的香樟（Cinnamomum camphora）绿色凋落叶和自然衰老的生理性凋落叶同步培养在草坪上和土壤表面。结果表明：草坪上的生理性和绿色凋落叶剩余质量均显著低于土壤表面，两个微生境中的生理性凋落叶剩余质量均显著高于绿色凋落叶。而且，草坪上的生理性衰老和绿色凋落叶碳（C）剩余量均显著低于土壤表面。此外，绿色凋落叶的C和氮（N）剩余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C、N、磷（P）剩余量出现显著下降。特别是，土壤动物显著降低了凋落叶剩余质量及C、P剩余量，对绿色凋落叶分解的影响强于对自然衰老凋落叶的影响。我们得出结论：绿色和自然衰老凋落叶在不同微生境中表现出明显不同的分解模式。
