图2. 入侵区域与无入侵区域土壤的氮含量(A)和入侵区域相对于无入侵区域土壤氮含量的相对变化(B) (平均值+标准误差)。*表示入侵区域相对于无入侵区域土壤氮含量变化显著(p < 0.05)。
Fig. 2. Soil N contents in invaded and uninvaded areas (A) and relative variation (RV) values of soil N contents in invaded areas compared to uninvaded areas (B) (mean + SE). * indicates significant variation of soil N contents between the two types of areas (p < 0.05).
