Abstract

The effects of human disturbance on species diversity of natural mixed stand of conifer and broad-leaved trees in Suobuya Stone Forest were discussed in this paper. The results showed that the human disturbance didnt change the dominant positions and roles of Pinus massoniana and Cunninghamia lanceolata in arbor. But it decreased the average diameter at breast height（or basal diameter） and average tree height and changed the species composition. The medium and light disturbance lowered the roles and positions of the broadleaved tree in arbor layer and the dominant species in shrub layer and hence lowered their important values，but it increased the diversity of community species. Of the communities under disturbance，the Shannon-Weiner diversity index was larger when the vertical height was below 1.0 m and the largest between 1.1 m to 3.0 m. Then the diversity index decreased with the height. There was no diversity when the height was over 9.1 m.［Ch，3 fig. 3 tab. 13 ref.］
