OHNO, Keiichi (Bot. Inst., Hiroshima Univ., Hiroshima). 1982. A phytosociological study of the valley forests in the Chugoku Mountains, southwestern Honshu, Japan. Jap. J. Ecol., 32 : 303-324. Communities of the alliance Pterocaryion rhoifoliae developed in valleys in the cool temperate zone of the Chugoku Mountains were classified into two associations of Pterocarya rhoifolia and an association and one community of Fraxinus platypoda. These communities are distributed differently in the East and the West Chugoku Mountains, which are divided by the Go River basin. This geographical border line of the distributional range was supported by climatic divisions based on the Japan Sea index. Occurrence ratio between the Japan Sea side and the Pacific side elements were calculated in each community. The rate of the Japan Sea side element was generally large in the stands of the Pterocarya rhoifolia communities, but that of the Pacific side element tended to increase in the stands located in the southern parts of the ranges. As a peculiar phenomenon, Fraxinus platypoda communities in which the rate of the Japan Sea side element is comparatively large are developed in the valleys of the Chugoku Mountains.
