The community structure characteristics of Quercus Secondary Forests were vestigated and analyzed in the eastern section of Funiu Mountain.The results showed that,Quercus alienai was the dominant species in the arbor layer with an important value of 46.80%,followed by Quercus acutissima and Cotinus coggygria;According to the relative prominence of top 3 species were Quercus alienai、Quercus acutissima and Quercus variabilis,their total relative prominence account for 99.04%;The results of comparison for diversity index(R,H,D,J)among tree,shrub and herb are shru＞herb＞tree;The tree species in the diameter class and upper layers are mainly Quercus alienai,the quantity of trees species and trees gradually increase from upper to lower layer,the DBH class distribution of trees in both plots were reverse-J-shaped,Community is in the young forest to Middle Aged forest succession stage,natural regeneration ability is strong.
