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