Impact on composing and diversity of understory plants from tourism disturbances

Composing and diversity of understory plants by tourism disturbances were analyzed to post impact of tourism exploitation to understory plants in this paper.The results showed that:The highest diversity index values were found for arbor layer under the low disturbance.The highest diversity index values were found for other layers under the intermediate disturbance.Respectively,higher than those under the low disturbance, especially for the shrub and herb layers.And diversity index is negative correlation to dominance index.
