Cryptocarya chinensis spatial distribution patterns caused by human disturbance in the lower subtropical monsoon evergreen broad-leaved forest
人为干扰下南亚热带厚壳桂种群分布格局(英文)

Lower subtropical monsoon evergreen broad-leaved forests are of high conservation significance in South China.Because of human activities,the forest has been largely destroyed;the remaining fragments are now mainly in several protected reserves.To further protect this forest outside the reserves and to study human influences on it,we analyzed the spatial pattern of Cryptocarya chinensis,a dominant tree in the forest near Changlong village,Guangzhou,China.Compared with low human disturbance forests,in which C.chinensis was clumped,we found that trees were randomly distributed,especially the young life stages.Human activities in this forest have also led to the decline of the C.chinensis seedling bank,suggesting that the population is regenerating badly.
