Abstract: Pinus gunnanensis var. tenuifolia is extensively distributed in the hills and mountains with an altitude from 300-1600m. along the lower Nanpan-jiang river. There it constitutes a large area of forest and forms an impo-rtant base of timber production.This paper deals with its phytocoenological features, including community physiognomy, tructure, floristic composition and succession.Analysis of these features indicates that it can be considered as a seral community. It will be necessary to promote reproduction and growth of the trees by use of suitable measures in order to reach sustained utilization.
