In this paper,the change law of >0.25 mm water stable aggregates,aggregates destruction rate and water stable aggregates fractal dimension under different vegetation restoration period and the correlation of the three indices with SOC content were studied in Ziwu mountain.The result showed that these three indices of 0-70 cm soil layer could be effected by vegetation restoration;the content of >0.25 mm water stable aggregates increasing and the aggregate destruction rate and water stable aggregates fractal ...
