图4 高寒草甸土壤水分储量(a)和土壤水分通量(b)的结构方程模型 注:实线表示显著正效应,虚线表示显著负效应,点线表示不显著。线段上的数字为标准作用系数,线段的粗细为标准作用系数的10倍。显著性水平用ns表示(P>0.05),*(P<0.05)、**(P<0.01)和***(P<0.001)。

Fig. 4 Piecewise SEM models for soil water storage (SWS) (a) and soil water flux (SWF) (b) in the alpine meadow Note:Solid (dashed) lines showed positive (negative) relationships;dotted lines showed that relationships were not statistically significant. The numbers that annotate the arrows were the standardized path coefficients,the weight for each line was ten times the standardized coefficient. With significance levels indicated by ns (P>0.05),*(P<0.05),**(P<0.01) and ***(P<0.001).
