图1. 冻融循环对土壤氧化亚氮(N2O)通量、N2O累积排放量、微生物生物量氮含量、硝化和反硝化作用速率的影响。误差棒表示95%置信区间, 误差棒后面数值代表变量观察数。虚线表示效应值为0。
Fig. 1. Effects of freeze-thaw cycles on soil nitrous oxide (N2O) flux, cumulative N2O emissions, microbial biomass nitrogen (MBN) content, nitrification, and denitrification rates. Error bars stand for 95% confidence intervals. Values next to the error bars represent the number of observations of the variable. Dashed line indicates that there is no effect.
