To investigate and analyze the change of the vegetation community structure between the severely damaged time (in 1980) and the restored time (in 1987) by the pine gall midge. Thecodoplosis japonensis, four plots with five subplots were sampled at Gwangju-gun of Kyongki-do. The total number of woody species per 500㎡ changed 39 in 1980 to 41 in 1987. According to the damage restoring, the importance value of the genus Quercus as substituting in the severely damaged forest showed a slight decrease but the importance value of Carpinus laxiflora, Sorbus alnifolia and Styrax obassia increased. As to changes of the vegetation community structure for seven years, the diversity of vegetation structure has increased. The similarity indices between 1980 and 1987 were 52.9% and 51.9% in the understory and shrub stratum, respectively.
