Abstract

Abstract: By using the niche breadth,niche overlap,TWINSPAN and DCA,the gradual change of the dominant species's niche of natural restoration vegetation and the relationship of communities have been studied. Based on the investigation of natural restoration community of mining wasteland in Beijing Shouyun Iron Mine,9 main populations were screened out for analysis of niche. The result showed that among the main populations the niche breadth of Vitex negundo was greater than that of other species. The results of niche overlapping showed that the species with big niche breadth will have niche overlapping with other species in the great opportunities. The result of DCA and TWINSPAN reflected the niche grade of the dominant species,the structure grade of and the environmental grade of community.

Key words: niche breath, niche overlap, TWINSPAN, DCA, natural restoration, Beijing Shouyun Iron Mine
