Abstract

Human disturbance strongly impacts a forest ecosystem. We want to know the quantitative relation of the disturbance intensity and the forest structure. In this research forest tree species composition，importance values of tree species，and community structure of a subalpine forest ecosystem in Shangri-La County were studied using 12 sample plots with three types of intensities of human disturbance. Results showed that human disturbance increased tree species diversity. Moreover，with an increase in disturbance intensity，forest species diversity declined. In addition，structural fragments（no tree layer） appeared in disturbed forest communities，and stand volume decreased. Thus，succession in the forest ecosystem was being damaged，suggesting that plantations of timber forests，non-timber forest products，and fuelwood forests could be used to help mitigate the human disturbances as well as alleviate dependence on the forest resources. ［Ch，4 tab. 15 ref.］
