Abstract:
The effects of the different artificial disturbances on the flora of tree layer and species diversity in the restoration series (CK,the natural Castanopsis carlesii forest; class A,the regeneration by selected cutting;class B,the natural regeneration in clear-cutting;area C,the artificial measures promoting regeneration and class D,Chinese fir stand) of the C.carlessi forest in Wuping, Fujian were studied. The results showed that the C. carlesii was the dominant species in the tree layer in CK, class A and class B;and the second dominant species in class C. The intolerant tree species C.fissa was the most dominant species in class C, and Chinese fir was the absolutely dominant in class D influenced by artificial plantation. Numbers of families,geneus and species; numbers of species in families, numbers of genera in families and numbers of species in genera were increased to B or C class and then dropped down gradually of directly with the increasing of disturbance intensities, while the indices of species diversity and the evenness decreased, the dominant index increased linearly. In class D, the indices were very different from those of natural C.carlesii forest because the dominant species-Chinese fir, which affected the characters and environment of the community. The regeneration patterns except class D will be succeed back to the climax community of C.carlesii.
Key words: C. carlesii forest, Artificial disturbance, The flora and species diversity of tree layer
