Abstract
By study features of recovering vegetation and physics and chemistry characters of soil in embankment slopes of 3 years and10 years respectively, the correlation among those factors were investigated . The results show: the physics and chemistry characters of soil vary observably with recovering process; Soil bulk density decreases while soil moisture,TP,TNand organic matter content increase evidently; Although the coverage of vegetation changes little, the structure of vegetation community becomes more complex and spatial distribution is more even; The correlation between spatial distribution of vegetation and characters of soil is most remarkable. With process of restoration, the vegetation is affected more effectively by water and nutrients in site.
