胜利一号露天煤矿排土场植物多样性研究

以内蒙古锡林郭勒盟胜利一号露天煤矿排土场为研究对象,通过对排土场植物群落组成的调查,利用应用值计算露天煤矿排土场植物丰富度指数、多样性指数、均匀度指数,分析排土场物种的多样性,为胜利一号露天煤矿排土场生态修复提供理论和技术依据。结果表明,胜利一号露天煤矿排土场的总共物种数为82种,隶属28个科,禾本科、菊科、豆科是排土场植物群落的主要物种；在人工恢复措施下,排土场植物群落逐渐由一年、二年生草本植物为主的群落演替为多年生草本植物为主的群落。排土场Margalef丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数、Simpson多样性指数数值南排土场最高。

Research on plant species diversity of Shengli No.1 open-cast coal mine

The paper took the Shengli No.1 open-cast coal mine as the research object. through the survey of mine plant community composition, application value is used to calculate open coal mine plant richness index, diversity index, evenness index, site analysis of species diversity, to win one open coal mine provide theoretical and technical basis for ecological restoration. The results showed that 82 species were found in the dump site of Shengli No.1 opencast coal mine, belonging to 28 families. Under the artificial restoration measures, the plant community in the dump site gradually changed from one-and biennial herbaceous plants to perennial herbaceous plants. Margalef richness index, Shannon-Wiener diversity index, Pielou evenness index and Simpson diversity index were the highest in the south dump.
