摘　　要：以抚顺西露天矿区为研究对象,对植物群落多样性与土壤理化性质进行了调查研究,分析了恢复时间和恢复方式对矿区群落多样性和土壤理化性质的影响,以及植物群落与土壤因子之间的相关性。结果表明:矿区土壤pH呈中性至弱碱性,且随着恢复时间的增加呈现降低的趋势;除磷素以外,其它养分随恢复年限的增加逐渐升高;随着恢复时间的延长,矿区植物Shannon-wiener和Simpson多样性指数逐渐增加;植物群落多样性受土壤化学性质的影响大,自然恢复与人工恢复相结合的方式对群落生态环境的恢复具有促进作用。The article takes Fushun West Open-pit mining area as research object,investigates plant community diversity and soil physicochemical property,analyzes the effects of different recovery periods and modes on the plant community and soil physicochemical properties,and the correlation between the plant community and soil factors.The results show that soil pH in the study area is neutral to slightly alkaline,and decreases with the increase of recovery periods.Except for phosphorus,the other nutrient indexes increases with the extension of the recovery period;Simpson and Shannon-Wiener diversity index increases with the extension of the recovery period.The effect of soil chemical properties on community diversity is higher than that of soil physical properties.The combination of natural restoration and artificial restoration can promote the restoration of community ecological environment.
