摘要
采用野外调查和统计分析相结合的方法,对海州露天矿不同排土场物种多样性进行研究。结果表明:不同排土场,物种组成变化较大,由草本群落逐渐演变为乔木群落;物种综合多样性指数、物种丰富度指数与排土年限呈显著的正相关关系。
The plant species diversity of opencast coal mine spoils in Haizhou was studied with field investigation and statistical analysis. The results show that the species components of different coal mine spoils changed, from herb community to tree community. There was prominent positive correlation between the diversity index, species richness index and the dumping years.
