The community species diversity dynamics of the early and medium restoration succession stages(0~50 a) of the forests in the Heishiding mountain area of Guangdong Province is systematically studied in this paper.Investigations on fixed quadrats combined with the method of the substitution of space for time,are employed in this study.The results show that in general,the community's biodiversity increases gradually with the process of the forest restoration succession which evolved from secondary bare lands of clearcut or fired remains to coniferous and broadleaved mixed forest at the early and medium stages of the secondary succession.That is to say,the species diversity raises step by step and the evenness of the forest community remains stable,while the ecological dominance of the communities tends to decline.In addition,it is found that the community's transparence imposed strongest impact on species diversity while no significant effect of the other 5 environmental factors on species diversity was detected based on the grey system correlation analysis between 6 dominant environmental factors and 4 species diversity factors.
