Table 3 Decomposition characteristics of leaf litter based on Olson’s exponential decay model.
From: Schrenk spruce leaf litter decomposition varies with snow depth in the Tianshan Mountains
Snow cover depth | Regression model | Decomposition constant k | Coefficient (R2) | Time to 50% decomposition (a) | Time to 95% decomposition (a) |
|---|---|---|---|---|---|
No | \(y = 1.003e^{ - 0.277x}\) | 0.277 | 0.942 | 2.502 | 10.815 |
Thin | \(y = 0.995e^{ - 0.280x}\) | 0.280 | 0.958 | 2.476 | 10.700 |
Medium | \(y = 0.989e^{ - 0.299x}\) | 0.299 | 0.972 | 2.318 | 10.020 |
Thick | \(y = 0.989e^{ - 0.322x}\) | 0.322 | 0.972 | 2.153 | 9.304 |
Entirety | \(y = 0.994e^{ - 0.294x}\) | 0.294 | 0.964 | 2.358 | 10.190 |
