Abstract: The study on the smoke-tree (Cotinus coggygria var. cinerea) scrub was carried out by the methods of pointquarter and quadrat in Qingzhou Mountain area of Shandong Province. In the present paper, the spatial pattern and main species dispersion of scrub was reported. It was found in this study that the Shannon-Wiener diversity index increases with the increase of the resources content. The patchness indexes and niche breadth are different, not only on the same resource axis among species, but also on the different resource axis within one species. The value of niche overlap between every two species is high on soil resource axes, so the species are possibly competitive for utilizating these resources.

Key words: Cotinus coggygria var. cinerea scrub, Species diversity, Niche metrics
