Abstract:

The effects of human disturbance on community features of Cunninghamia lanceolata mixed forests were studied,the results showed that:1)the proportion of phanerophyes in the not burning forests were larger than in the control burning forests; 2)the species richness in the control burning forests were larger than that in not burning forests,but the species diversity and Simpson evenness in the control burning forests were lower than that in the not burning forests;3)the effect of control burning on the dominant species in tree and shrub layers of Cunninghamia lanceolata mixed forests were little, but on the herb layer was very large,which dominated by positive plant species; 4)the community structure was more complex which would increase the crown density of stand.

Key words: Human disturbance, Cunninghamia lanceolata mixed forest, Community feature
