Abstract: In the present paper, leaf nutrient and structural characteristics of 32 evergreen broadleaved plant species were studied. The results are as follows: leaf N varies from 1.022% to 2.744%, the average is 1.606%; leaf P varies from 0.032%~0.227% and the average is 0.086%;N and P are positively correlated; leaf C varies from 36.49% to 53.85%and the average is 45.00%;SLA varies from 72.64 to 197.78 and the average is 119.29;leaf C is negatively correlated with SLA, but nutrient content isn't correlated with leaf C or SLA of these three life forms isn't significant.

Key words: leaf nutrient, leaf structure, evergreen broad-leaved species, leaf nutrient, leaf structure
