Abstract:: The evaluation of soil and water conservation function to vegetation effect on coal waste piles of 5 restored vegetations in Fushun West waste-dump are calculated and compared through principle component analysis by setting up a series of indexes, including canopy interception, canopy height, canopy density, coverage, litter of weeds interception amount, litter of weeds thickness, effective density of roots. With the statistical software SPSS 13.0, the evaluation of soil and water conservation function is calculated. From high to slow, the restoration of 3 years are shrubby falseindigo, Sea-buckthorn, Locust, Simon poplar, Chinese pine, the restoration of 5 years are shrubby Locust, falseindigo, Sea-buckthorn, Simon poplar, Chinese pine. Research shows that the evaluation of soil and water conservation function of shrubs is better in early restoration of vegetation. As time passes the evaluation of soil and better conservation function of broad-leaved trees become better and better.The authors advise that the broad-leaved trees and shrubs mixing apply to coal waste piles to reconstruct ecological.
