In this paper, I treat of the distribution of vegetation division by records of monthly mean temperature and monthly average precipitation from 1931 to 1960 in Korea, and explain climatic characteristics of vegetation regions which are composed of woody plant and herbaceous plant. The results of the analysis may be summarized as follows: (1) The vegetation zone of woody plant and herbaceous plant are divided into three types by three climatic regions. That zone of herbaceous plant is divided into six types based on the method of Klima-diagramm. (2) The forest zone is classified according to temperature and amount of precipitation. The approximate boundary line between the evergreen needle-leaved forest region and the deciduous broad-leaved forest region is decided by warmth index 85, precipitation effectiveness ratio 60, and potential evapotranspiration 650. And the demarcation between the deciduous broad-leaved forest region and the evergreen broad-leaved forest region is fixed on warmth index 110, continentality 58, and oceanity 13. (3) According to temperature of 0.5℃ and 1.0℃ in the type of the hotest month, the herbaceous plant is classified into the continental type (Forage type, Sasamorpha type), the transitional type (Miscanthus type, Pteridium type), and the maritime type (Zoysia type, Phragmites type). While, in case of setting up continentality 67 and 55 as a criterion of classifying grasslands, there are appeared some differences in location. (4) The grassland region based on temperature and precipitation are divided into six homoclimatic types which show N-S direction in southern area and E-W direction in northern area. The regional arrangement of three grassland types caused by temperature appears N-S direction in the whole country. (5) In the climatic characteristics of the vegetation zone, the frigid zone is cool in summer and severe in winter, and is belonged to the cold temperate climate within the annual range of temperature of being between 35℃ and 44℃. The amount of precipitation in this zone is between 500mm and 950mm. The temperate zone which has hat summer and comparatively cold winter is compounded the warm temperate climatic region and the cold temperate climatic region. Annual precipitation reached between 950mm and 1300mm is more than that of the frigid zone. The subtropical zone has hot summer and mild winter as a maritime climatic region, so the annual range of temperature becomes the smallest. Since it precipitates normally between 1300mm and 1800mm in a year, this zone forms the heaviest rainfall area.
