Woody materials decayed more rapidly in a first order stream than in larger streams in eastern Quebec, Canada. The rate of annual mass loss (k) was highest (k=1.20) for alder wood chips in a first order stream and lowest (k=0.04) for black spruce wood chips in a ninth order stream. Decay rates for woody materials in a first order stream were inversely related to their initial lignin to nitrogen ratios. In larger streams, decay rates of woody materials were inversely related to their initial lignin concentrations. A number of quantifiable relationships were found to exist between the initial lignin and nitrogen contents of woody materials and the nitrogen dynamics of decaying wood.
在加拿大魁北克省东部,木质材料在一级溪流中的腐烂速度比在较大溪流中更快。一年生质量损失率(k)在一级溪流中的桤木木屑中最高(k = 1.20),而在九级溪流中的黑云杉木屑中最低(k = 0.04)。一级溪流中木质材料的腐烂率与它们初始的木质素与氮的比率呈负相关。在较大溪流中,木质材料的腐烂率与它们初始的木质素浓度呈负相关。人们发现木质材料的初始木质素和氮含量与腐烂木材的氮动态之间存在一些可量化的关系。
