不同大写字母表示相同土层不同样地之间差异显著,不同小写字母表示相同样地不同土层之间差异显著（P<0.05）。下同
Fig. 2. Variation of destruction rate of soil aggregate and fractal dimension of different restoration age sites of gully heads
Different capital letters and lowercase letters indicate significant difference at 5% level between different sites in the same soil layer and between different soil layers in the same site, respectively. The same as below
