In this study,spatial structure parameters such as uniform angle index,size ratio,and mingling degree which based on the nearest four adjacent tree structure unit were used to analyze the spatial structure characteristics of the evergreen broad-leaved forest community in the Wuyi Mountains; this analysis was based on the examination of the tree layer of a community in a 9. 6 hm~2 dynamic forest plot. This analysis method eliminated the influence of the mesoscale effect,unlike traditional analysis patterns. ...
