%X The dynamic state of population of evergreen broadleaf trees were investigated after human disturbance by studying the spatial distribution patterns of several main populations(Castanopsis eyrei,Syzygium buxifolium,Schima superba,Michelia maudiae) in castanopsis eyrei communities.After the communities are disturbed in different levels, the distribution of populations presents various change trends.The heavier human-caused disturbances,the more obvious aggregate nature of Castanopsis eyrei,Michelia maudiae and the less obvious aggregate nature of Syzygium buxifolium,Schima superba.On the low stand classes of trees, slight human-caused disturbance benefits the formation of aggregate distribution characteristics.On the middle stand classes of trees,the aggregate nature of trees,whose seeds,roots and branches have strong sprouting power,is more obvious in the intense human-caused disturbance.On the high stand classes of trees,the distribution pattern of population shows a random distribution.
