摘要: 采用TWINSPAN、DCA和DCCA,从植物种、植物群落与环境因子关系方面对平朔安太堡矿区的人工植被在恢复过程中的生态关系进行了研究.结果表明,将63个样方划分为12个群落类型,反映了植物群落与环境梯度之间的关系,并列举了各群落的特征.DCA排序图明显反映出排序轴的生态意义,随着复垦时间的增加,土壤含水量也不断升高.DCCA排序进一步表明了土壤有机质含量是所有因子中对植物群落发展起决定性作用的主要环境因素.

Abstract: By the methods of TWINSPAN,DCA and DCCA,and from the aspects of the relations between plant species,communities and environmental factors, this paper studied the ecological relationships among artificial vegetations during their restoration in Antaibao mining area.63 collected quadrates were classified into 12 community types by TWINSPAN,and the distribution of the communities could comprehensively reflect the influence of environmental factors.DCA ordination indicated that soil water content,which was increased with restoration time,was the main factor restricting the distribution of the communities.DCCA ordination showed that soil organic matter content was the decisive factor to the development of communities.
