The Revision of Plant Life- form System and an Analysis of the Life- form Spectrum of Forest Plants in the Warm Temperate Zone of China

GAO Xian-Ming and CHEN Ling-Zhi   

Abstract: The Raunkiear' s plant life-form system was revised, according to the features of the forest plants in the warm-temperate zone of China, and based on the revised system, the life-form spectrum analysis has shown that the hemieryptophytes are the dominant life-form, accounted for 33. 9% of all the forest vascular plants, followed by the geoeryptophytes, which cover 19.7%, and all of the phanerophytes make up 27.5 %. There are only few macrophanerophytes, being higher than 25 m, because of human activties as well as the inadequate water and temperature supply in this area. The general spectrum of the warm-temperate zone of China eould basically represent the charactefisties of middle latitude climate that is rainy and warm in summer, and frigid and dry in winter.

Key words: Warm-temperate zone of China, Plant life-form, Life-form spectrum, Revision
