凋落物和土壤有机质分解是特定生态系统中碳和养分循环的主要驱动力之一;然而，它也有助于大量产生相关温室气体。日本群岛跨越几个生物群落（北温带-亚热带），覆盖了大范围的海拔和生态系统类型。因此，理解不同生态系统中的这一基本生物地球化学过程对于维持其生态系统服务至关重要。在这篇文章中，我们提供了来自日本33个研究地点的植物叶片分解数据。在2012年至2016年期间，在每个地点，将具有不同分解率的标准凋落物材料、路易波士茶和绿色茶孵育90天，并记录剩余质量。总共使用了1904袋。此外，还记录了对解释所收集的数据至关重要的环境变量的补充测量结果，如土壤和植被。培养后袋内容物的剩余质量率的图水平平均值为绿色茶的0.17-0.51和路易波士茶的0.54-0.82。继续监测也将提供重要的洞察力的时间动态凋落物分解。
Litter and soil organic matter decomposition represents one of the major drivers of carbon and nutrient cycling in a given ecosystem; however, it also contributes to a significant production of relevant greenhouse gasses. The Japanese archipelago spans several biomes (boreal-temperate-subtropical) and covers a large range of elevations and ecosystem types. Hence, the comprehension of this fundamental biogeochemical process in diverse ecosystems is crucial to maintain their ecosystem services. In this article, we have provided data on plant leaf decomposition from 33 research sites across Japan. At each site, standard litter material with different decomposition rates, rooibos tea, and green tea were incubated for 90 days between 2012 and 2016 and the remaining mass was recorded. In total, 1904 bags were used. In addition, supplementary measurements of environmental variables essential for the interpretation of the collected data, such as soil and vegetation, were recorded. Plot-level averages of the remaining mass rates of bag contents after incubation ranged 0.17-0.51 for green tea and 0.54-0.82 for rooibos tea. Continued monitoring will also provide important insights into the temporal dynamics of litter decomposition.
