Abstract: Using conventional plant community survey methods three rocky slopes were constructed to simulate physicochemical properties of soil and the artificial vegetation restoration of the Guiyang City beltway south loop in an indoor experiment. It was found that: 1) The content of alkali hydrolyzable nitrogen (AN), available potassium (AK), available phosphorus (AP), organic matter (OM) showed an upward trend, by 2013, the average content of AN reached a lower level, the average content of AK maintained high level, the average content of AP reached a higher level, the average content of OM at the middle level. 2) With longer recovery time, slope total species number has increased substantially and the fluctuation of gradual, they have seasonal variation, Species composition and proportion and dominant changed, to change to the local natural vegetation. 3) In 2009 July-2012 year in June, plant herb layer coverage and high risen, by 2013 they have reduced, a certain number of shrub planting in the slope, and the slope restoration effect is good. 4) There are 18 pairs of significant correlation indicator between slope community total species number, plant height and coverage, the soil available nutrients N, P, K and OM, but in the relationship between soil nutrient and plant community characteristics, only AN and AP and total plant species, shrub layer plant height have significantly correlation.
