摘要 在植被现状调查的基础上,采用物种多样性指数法,对南峪口铁矿生态影响评价的植物物种多样性进行了比较,结果表明:该矿的植被可划分为8个群落类型,反映了矿区不同功能区的植物群落主要类型。根据物种多样性指数的计算结果,不同功能区的植物物种多样性表现出明显差异,按照物种多样性指数大小排序:矿界外评价区>矿区非开采区>拟选废石场>相邻矿区>工业场地>炸药库>铁矿开采区,反映了铁矿开采活动对周边环境干扰程度的差异性。 This article uses the biological diversity index to investigate the plant species diversity of ecological impact assessment in Nanyukou iron mine .The results show that the sample plots can be classified into 8 community types , which are the main types of the plant community of different function areas in the iron mine .The calculated value of the biological diversity index demonstrates significant differences of different function areas .According to the value of Shannon-Weiner index , the species diversity of different function areas is in the following order :the outside appraisal district>non-mining areas of the mine>slagging field> the adjacent area of the mine> the industrial sites> powder storage > exploitation area , which reflects the disturbance intensity to the surrounding environment . Simpson index can reflect the status and the function of dominant species in the plant community .
