The Effects of Human Disturbance on Biomass and Plant Diversity of Musa acuminata Community

The biomass and diversity of Musa acuminata communities under different disturbance pressure was studied by sample tree and regression analysis (for tree layer). The results showed that the Musa acuminata invading into shift terra did not influence the biomass indistinctively. Disturbed by human being, the biomass became lower. The results also show disturbed Musa acuminata community would keep a condition of big amount population, lower species diversity and high important value. In the shift terra, Musa acuminata invade in and expansion rapidly was a normal way of community succession. It was suggested that protection community from jamming was a good way to keep the Musa acuminata community succession on right way.
