Abstract:
The authors mainly studied the initial ecological recovering process of porcelain clay mine of gangue sand hill of Dapailing in Xingzi Town of Jiangxi Province. On base of the sites investigation, they analyzed the man-made recovering woodland, the non-controlled area, as well as the quantity of plant species, and community composition and structure in the naturally recovering area. The result showed that the effects of biodiversity and community composition and structure were superior to those of non-controlled area and the man-made recovering area. The residence and diffusion of three kinds of plant including Negundo Chastetree, etc. in the naturally recovering area formed the plant community type with certain composition and structure, and moreover the community type was stable and conforms to the nature rule of the vegetation evolution. The three kinds of pioneer plants could be extended to the vegetation reconstruction and recovery of the gangue sand hills of similar mine hills.
