STUDY ON THE MORPHO ECOLOGY OF LEAVES OF THE MAIN SPECIES IN THE EVERGREEN BROAD LEAVED FOREST DOMINATED BY CYCLOBALANOPSIS GLAUCA

The leaf morphology of the main species in the evergreen broad leaved forest dominated by Cyclobalanopsis glauca was ellips roughly, and the area was between 15～40 cm 2/leaf. The leaves belong to middle and small type leaf; The size of the leaves in a tree were in conformity to the normal distribution except for Lithocarpus; The leaf size of the main species was C. glauca (dominant species)L. glaber (sub dominant species)other species, that was an ecological adaptation in the community structure differentiation, i.e. they have the different “growth strateges” of the species; The leaf size of the same specis was upper layer individiual leavesmiddle layer individual leaves; The leaf size reached the first peak during the spring summer and the second peak during late autumn winter,the specific weight of the leaf was higher in autumn and winter than in spring and summer,that was the adaptation of the evergreen trees to the seasonal unfavorabale climate.
