Community Structure of Forest at Different Elevations in Cenwanglaoshan Natural Reserve
摘要
Abstract
The sample plots of forest community at elevation of 1 350 m,1 550 m and 1 850 m at Cenwan-glaoshan natural reserve were analyzed to discuss the influence of elevation gradients on plant community struc-tures. Results showed that there were 49 families, 131 genera and 302 species, and the species decreased gradually with increase of elevation. The highest biodiversity index was at 1 350 m, and the Simpson index and Pielou evenness index of plots at 1 850 m were slightly higher than those at 1 550 m , but the Shan-non-wiener index was lower than that of 1 550 m. When elevations of communities were closer,the similarity coefficient was higher. It was indicated that the community composition continuously changed with elevation.关键词
