In order to improve the qualities of ecology and landscape of Platyclatdus orientalis plantation in limestone mountain in Xuzhou,the growth rhythm of Platyclatdus orientalis plantation in Yunlong Mountain was studied with the method of stem analysis.The results showed that: The logarithmic equation was superior to the growth process of diameter at breast height(DBH) and tree height in the P.orientalis plantation,and the Logistic equation was superior to the growth process of stem volume,and these growth model had a good correlation.The average and annual increment of DBH and tree height was highest in the 10-year-old plantation,but the stands were still not into maturity.There were three pronounced peaks appeared every several years in the growth process of DBH,which could be used to guide the thinning and tending.This study provided theoretical bases for the comprehensive management of P.orientalis plantation in future.
