[Investigation on the vegetation of copper tailing wasteland in Shizishan, Tongling, Anhui Province].
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), Graminease (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.
