Relationships Between Geographical Distribution of Cyclobalanopsis glauca and Climate in China

Ni Jian and Song Yong-chang   

Abstract: Cyclobalanopsis glauca (Thunb.) Oerst., which belongs to China-Japan subtype of East Asia district, is a evergreen broadleaved tree of Fagaceae. It is distributed widely in the subtropical region of China and also in Japan, Korea, India, Burma, etc. According to the data on geographical distribution of this species collected extensively, the indexes of vegetation-climate interaction which used widely in the world were calculated. These indexes include Kira' s water-temperature indexes, Penman's formula, Thornthwaite's indexes and climatic classification, Holdridge's life zone classification system, annual average temperature, mean temperature in January, mean temperature in July, maximum temperature, minimum temperature, ≥10 ℃ accumulated temperature and precipitation. The relationships between geographical distribution of Cyclobalanopsis glauca and climate in China has been analysed and the Kira's water-temperature indexes on the distributional upper limit, lower limit and north limit have been discussed. The relation of species versus climate in historial period and the relation of species versus climate in historial period have also been discussed according to palynological and written records. The potential change of the tree species distributional area under elevated CO2 concentration has been forecast based on Holdridge' s indexes of life zone classification system and GCM models' conclusions.

Key words: Cyclobalanopsis glauca, Geographical distribution, Meteorological indexes, Palaeovegetation and palaeoclimate, Global change
