矿山生态修复边坡植物多样性分析研究

Analysis and study on plant diversity of ecological restoration slope in mines

为充分提升矿山生态修复效果,提出矿山生态修复边坡植物多样性分析方法。该方法以某矿山区域内12个生态修复边坡为主要研究对象,通过样地法沿线调查生态修复边坡的自然概况和植物情况。选取辛普森Simpson多样性指数和Pielou均匀度指数作为衡量矿山生态修复边坡植物多样性的指标,并利用统计软件SPSS22.0对生态修复矿山边坡植物状况数据进行统计分析,得到边坡植物多样性分析结果。研究结果表明,应用该方法可有效获得12个矿山生态修复边坡植物的群落构成以及植物多样性的重要度;也可获得生态修复边坡植物种类出现频度,并可依据辛普森多样性指数和均匀度指数,得知不同矿山生态修复边坡植物类型以及分布情况,应用效果较为显著。

In order to fully improve the effect of mine ecological restoration,an analysis method of plant diversity of mine ecological restoration slope is proposed.This method takes 12 ecologically restored slopes in a mine area as the main research object,and investigates the natural situation and plant conditions of the ecologically restored slopes along the sample plot method.Simpson diversity index and Pielou evenness index are selected as the indicators to measure the plant diversity of the ecological restoration slope of the mines,and the statistical software SPSS is used to analyze the plant status data of the ecological restoration slope of the mine,and the analysis results of the plant diversity of the slope are obtained.The results showed that the community composition of plants and the importance of plant diversity in the ecological restoration slope of 12 mines could be effectively obtained by using this method.The occurrence frequency of plant species for ecological restoration of slope can also be obtained,and the type and distribution of plant species for ecological restoration of slope in different mines can be known according to Simpson′s diversity index and evenness index.The application effect is relatively significant.
