Ichifusa-yama (1,722m), Southe Kyushu. Quadrat ordination by PCA based on similarity matrix of the importance value, classified quadrats into the three groups; the first occurred on the lower part of slope, characterized by oak species, such as Cyclobalanopsis paucidentata, Cy. myrsinaefolia, Cy. gilva, etc, while the second with few character species occurred on the higher part of slope. The last was judged as the essentially different stand from the oak forest. Out of topographical factors, only altitude influences significantly on the variation of species composition. Species ordination by PCA based on an interspecific association matrix clarified five species-groups, of which the three were main constituent species of each of the three quadrat groups. The remaining two showed a peculiar preference for habitats. Species diversity, β, decreased as altitude became higher. Above ground biomass per unit area estimated by allometric relations was higher than those of the warm-temperate oak forests reported from other areas of Kyushu. The forest can be considered as a fully matured climax.}, pages = {67--88}, title = {市房山原生照葉樹林の植生構造}, volume = {24}, year = {1989}, yomi = {ミヤタ, イツオ and イマエ, セイチ and ウチノ, アキノリ and タカミヤ, マサユキ} }
