Evergreen broad-leaved forest （EBLF） is endemic zonal vegetation in warm and humid subtropics of China. Through typical plot investigation of EBLF in Minxi, the results indicate that there are 398 species seed plants which belong to 116 families and 235 genus, The EBLF in Minxi with varied community types, may be classified into 2 sub-vegetation types, 12 formation groups, 24 formations and 72 typical associations, and importance value （IV） of constructive species varies from 45.6 to 184. Machilus pauhoi formation, Lindera communis formation and Osmanthus fragrans formation is reported in Fujian at the first time. Simple illustration of their geographical distribution and habitat property is given, and scientific conservation and management method are put forward according to its situation.
