图5. 土壤团聚体活性有机碳对SOC影响的结构方程模型
实线和虚线分别表示显著正效应和负效应。箭头的宽度与强度的关系呈正比。线条附近的数字是标准路径系数,该系数显示了模型中的变量关系。图6

Fig. 5. The effect of soil active organic carbon on SOC in soil aggregates by structural equation model analysis
The solid lines and dashed lines represent significant (P<0.001) positive and negative effects, respectively. Arrow widths is proportional to the strength of the relationship. The numbers near the lines are standardized path coefficients, which show the variables in the model. The same as Fig. 6
