Study on re-vegetation and soil characteristics on the slope along the road in Beijing Shouyun Iron Ore

The natural and artificial restoration of vegetation was investigated on the slope along the road in Beijing Shouyun Iron Ore. Total 21 plant species were found in 10-year natural restoration. Among these species, there were 7 ones of Asteraceae, 5 of Gramineae. 14 plant species were found in 1-year artificial restoration. Among them, Gramineae，Fabaceae and Simaroubaceae contained 2 species respectively.18 plant species were found in 2-year artificial restoration.Among them,Gramineae,Fabaceae contained 3 species respectively.The plant community with artificial restoration was rich in plant growth form than with natural restoration. Covered with 10 cm hill-skill soil and choosing an appropriate plant, the recovery of a-diversity of plant communities was accelerated. The contents of available K and P increased to a certain degree respectively in top soil. For short-time artificial restoration and the consumption of nitrogenous fertilizer due to plant growing, the content of organic matter and total N with artificial restoration were lower than that with 10-year natural restoration.
