摘要
通过实地调查发现 ,铜陵市狮子山铜尾矿废弃地自然定居植物共 4 9种 ,隶属 15个科 38属 ,主要包括禾本科 11种、菊科 12种、豆科 8种等 .全部植物中 ,1、2年生草本植物 2 6种 ,多年生草本植物 2 0种 .形成了 5种相对稳定的演替群落 ,且群落物种单一 ,结构简单 .矿业废弃地土壤养分的贫瘠 ,重金属含量浓度高 ,尤其是Cu、Cd的含量平均超出正常土壤的 30倍 ,以及自然条件对其改造的程度是现今影响植物在其上定居。
Investigation on the vegetations of the copper tailing wasteland was conducted in Shizishan, Tongling, Anhui Province. Total 49 species of natural colonized plant, belonging to 15 families and 38 genera, were found, among which, 26 species were annual plant, and 20 species perennial. Most of species were belonging to Compositae (12 species), Gramineae (11 species), and Leguminesae (8 species). 5 relatively stable communities were found. The main limiting factors of vegetation distribution were extreme infertility of the wasteland, high concentration of heavy metals (especially, the concentration of Cu and Cd in the wasteland were 30 times as those in the normal soil), and degree of natural recolonization.
