Abstract A large data set (sample size >4000) of the decomposition rates of coarse woody debris was collected in field mass loss experiments along the macro-regional profile crossing the entire forest zone of the West Siberian plain (Russia). The profile passed through the entire latitudinal variety of boreal forest ecosystems from forest tundra in the North (67°) to forest steppe in the South (55°). The latitudinal pattern of the initial stage (3–11 yr) of woody debris decay is established, and the relative contribution of environmental factors and substrate quality to the decomposition rate is assessed. The data presented have no analogues in Russia or abroad either by volume or by the geographic coverage.

西西伯利亚森林区木质碎屑腐烂早期的纬度格局

摘要 在跨越西西伯利亚平原（俄罗斯）整个森林区的宏观区域剖面的现场质量损失实验中收集了粗木屑分解率的大型数据集（样本大小 >4000）。该剖面穿过整个纬度变化的北方森林生态系统，从北部的森林苔原 (67°) 到南部的森林草原 (55°)。建立了木质碎片腐烂初始阶段（3-11 年）的纬度模式，并评估了环境因素和基质质量对分解速率的相对贡献。所提供的数据在俄罗斯或国外在数量或地理覆盖范围上都没有类似物。
