图7 禁牧（A）、放牧（B）草地辐射通量与气候、土壤、植被因子的路径图 单箭头线称为直接路径，表示因果关系，方向由原因指向结果。实线表示正相关，虚线表示负相关，数字为路径系数β。*号表示显著性水平P值（***，0.001；**，0.01；*，0.05）

Fig.7 Path plot of radiation fluxes and climate， soil and vegetation factors in prohibited grazing （A） and grazing （B） areas. In the figure， the line with single arrow is called direct path， which indicates causality， and the direction is from cause to result. solid lines indicates positive correlation， dotted lines indicates negative correlation， and the number is the path coefficient β。The sign * indicates the significance level P value （***，0.001；**，0.01；*，0.05）
