Abstract With the aim to analyze the effects of vegetation restoration on soil aggregates on the Loess Plateau, various categories of the distribution and stability of soil aggregates in different restoration ages of vegetation zones were studied. With three typical restoration zones including the steppe zone, the forest-steppe zone and the forest zone at different latitude on the Loess Plateau as the object of this research. The results showed that the distribution and stability of soil aggregates were significantly influenced by vegetation zones. For the five indexes including > 0.25mm soil water-stable aggregates (WR_0.25), mean weight diameter (E_WMD), geometric mean diameter (E_GMD) and soil organic matter (SOM), these indexes in the forest zone were the highest, followed by the forest-steppe zone, and these in the steppe zone were the lowest. Different vegetation restoration condition and vegetation zone had different impacts on soil aggregates and their stability, with the trend of shrubs > grasslands > trees in the forest-steppe zone and trees > grasslands in the forest zone. pectively, indexes including WR_0.25、E_GMD and SOM in different restoration conditions increased with restoration ages, but other indexes including percentage of aggregate destruction (PAD) and soil erodibility (K) decreased. No significant difference has been found in the fractal dimension (D). The redundancy analysis showed that the distribution and stability of soil aggregates were mostly effected by the vegetation zones, and the restoration ages as following. The type of the restoration had a significant interaction with the vegetation zones and the restoration ages. This research is conducive to better understand the mechanism of regional ecological restoration process.
