图8. 年降水量(MAP)、年平均气温(MAT)、净辐射(Rn)和叶面积指数(LAI)对波文比(β)影响的路径分析图。结构方程模型(SEM)的统计结果为χ2= 1.75, df = 2, p = 0.093, RMSEA = 0.038。实线和虚线箭头分别代表正相关和负相关。每个箭头上的数字为标准化路径系数。粗体数字分别为LAI、Rn和β统计结果的解释度R2。
Fig. 8. Path diagrams for the effects of mean annual precipitation (MAP), mean annual air temperature (MAT), net radiation (Rn) and Leaf Area Index (LAI). The statistical results of the structural equation model (SEM) are χ2 = 1.75, df = 2, p = 0.093, RMSEA = 0.038. Solid and dashed arrows represent positive and negative correlations, respectively. The figure for each arrow is the standardized path coefficient. The bold numbers are the explained variance (R2) of LAI, Rn and β, respectively.
