摘　　要：本文采取实地样方调查的方法,分析不同恢复模式下植被群落结构组成和物种多样性特征。研究结果表明,人工恢复模式(连翘)共计包含物种17个,分属于10科17属,自然恢复模式(CK)包含物种15个,分属于9科15属,自然背景(BK)包含物种11个,分属于7科10属。细裂叶蒿、隐子草同时出现于3种处理类型中,细裂叶蒿相对重要值表现为BK>CK>连翘,隐子草则是连翘>CK>BK。细裂叶蒿在未受采矿活动干扰的自然群落系统中占比仅次于芦苇;隐子草按照BK、CK、连翘的顺序呈现出逐步增加趋势。丰富度、多样性和均匀度均表现出连翘模式高于自然恢复模式,也高于未受干扰的自然背景区域。通过人为引入连翘本地适生物种,能够在较短时期内实现演替进程和恢复情况较为明显提升。This article adopted the method of field plot investigation to analyze the composition of vegetation community structure and species diversity characteristics under different restoration modes.The research results indicated that the artificial restoration mode(Forsythia suspensa)contained a total of 17 species,belonging to 10 families and 17 genera,the natural restoration mode(CK)contained 15 species,belonging to 9 families and 15 genera,and the natural background(BK)contained 11 species,belonging to 7 families and 10 genera.Both Artemisia tanacetifolia and Cleistogenes chinensis appeared in3 treatment types simultaneously.The relative importance values of Artemisia tanacetifolia were BK>CK>Forsythia suspensa,while Cleistogenes chinensis was Forsythia suspensa>CK>BK.Artemisia tanacetifoli was second only to Phragmites australis in natural community systems that were not affected by mining activities;Hidden grass showed a gradually increasing trend in the order of BK,CK,and Forsythia suspensa.The richness,diversity,and evenness all showed that the Forsythia suspensa pattern was higher than natural restoration,and then higher than undisturbed natural background areas.By artificially introducing locally adapted species such as Forsythia suspensa,the succession process and restoration situation can be significantly improved in a relatively short period of time.
