对安徽省祁门查湾自然保护区亚热带常绿阔叶林成熟林分的结构特点进行了调查分析。结果表明：该林分在600 m2的样地内出现树种数（D≥3.0 cm）为11个,多样性指数为1.94,均匀度指数为0.81,低于我国东部中亚热带其他地区常绿阔叶林。但林下植被树种（D≤3.0 cm）多样性较高,出现树种数达21种,表明森林植被干扰后树种多样性得到了较好恢复。
對安徽省祁門查灣自然保護區亞熱帶常綠闊葉林成熟林分的結構特點進行瞭調查分析。結果錶明：該林分在600 m2的樣地內齣現樹種數（D≥3.0 cm）為11箇,多樣性指數為1.94,均勻度指數為0.81,低于我國東部中亞熱帶其他地區常綠闊葉林。但林下植被樹種（D≤3.0 cm）多樣性較高,齣現樹種數達21種,錶明森林植被榦擾後樹種多樣性得到瞭較好恢複。

The structural features of mature stands of the subtropical evergreen broadleaved forest in Zhawan Nature Reserve in Qimen,Anhui Province was investigated and analyzed.The results showed that there were 11 tree species（D≥3.0 cm） in the 600-m2 sample plot.The diversity and evenness indexes were 1.94 and 0.81 respectively,lower than those of the other evergreen broadleaved forests in mid-subtropical regions of East China.But the diversity of the undergrowth vegetation tree species（D≤3.0 cm） was higher with 21 tree species,showing that the diversity of the tree species in this subtropical forest has been recovering well after disturbances.
