摘要: 通过野外调查和实验分析,铜陵市几个铜尾矿场自然定居的高等植物共有89种,隶属于30个科73个属,主要包括菊科、禾本科、豆科,但蕨类植物节节草在尾矿库中也占据了重要位置。尾矿库植物形成了一些相对稳定的单种斑块和小群落,这些小群落组成、结构简单,物种多样性水平偏低。狗牙根、白茅、三叶草、天蓝苜蓿、中华胡枝子、节节草等可在铜尾矿库上成功定居,并具有较大综合优势比,可作为良好的铜尾矿库治理的优先选用物种。

Abstract: From the field investigation and laboratory analysis, this paper studied the vegetation state in the copper tailing yard of Tongling. The results showed that there were 89 species of naturaly colonized plants in the copper tailing yard, which belonged to 30 families and 73 genera. The main families were Gramineae (19 species), Compositae (16 species),and Legumineceae(9 species).Hippochaete ramosissimwn, which belong to Equisetaceae, had an important position too. The vegetation on copper tailing yard was distributed on spot piece and scattered with low species diversity.mainly composed of biernial and annual herbs. Cynodon dactylon, Imperata cylindraca, Lespedeza chinensis and Trifolium pratense etc. were dominant species that can be used for copper tailing treatment.
