中文摘要	通过对铜陵市狮子山铜尾矿废弃地植被的实地调查，探讨了该废弃地的植被状况及其植被恢复过程中的植物群落形成与演替的一般规律与特征。结果表明：目前废弃地入侵、定居植物共49种，隶属于15科38属，主要包括菊科(12种)、禾本科(11种)、豆科(8种)等。极端贫瘠和过高的重金属含量(特别是Cu、Cd，平均超出对照土样的20～30倍)是限制植物在废弃地定居的主要因素。全部植物中，一、二年生草本植物26种，多年生草本植物20种。风播种子和果实是废弃地植物繁殖体的主要来源。尾矿废弃地植物群落形成具有先锋植物的入侵、定居、群聚和竞争等过程，共形成了14种相对稳定的小群落，包括单优势种群落、次优势种群落和共优势种群落三种类型。伴随着尾矿废弃地植物群落的形成与演替，群落中物种丰富度增大，多样性指数呈增加趋势，而群落内植物种综合优势比间的差值趋于减小。
英文摘要	Through the field investigation and laboratory analysis, this paper describes the regular pattern of community succession on the deserted land of Shizishan copper tailings in Tongling City. There are 49 species of natural colonized plants on the wasteland, which are subordinate to 15 families and 38 genera. The main families are Compositae (12 species), Gramineae (11 species), Leguminosae (8 species) and Hippochaete ramosissimum, which belong to Equisetaceae. The extreme soil infertility and excessively concentration of heavy metals (especially Cu and Cd) are the main limiting factors to plants colonization. The vegetation on the deserted land of copper tailings is distributed in spot piece and scattered mainly with fewer species of plant, with lower species diversity. Annual and biennial herbs and grasses are dominant components. Cynodon dactylon, Imperata cylindrica var. major, Lespedeza chinensis, Erigeron annuus and H. ramosissimum etc. have a higher summed dominance ratio. The natural formation of plant community on the deserted land of copper tailings usually goes through seeds spread, invasion, ecesis, aggregation and species competition. After several years of primary natural restoration, 14 communities were formed. According to their community composition and structure level, the 14 communities are divided into three primary succession stages, namely monodominant, subdominant and codominant species communities. With the formation and succession of these communities, species were enriched and diversity increased, the margin of summed dominance ratio of species in each community decreased, and the composition or structure of community became complex.
