Abstract: This paper compares and analyzes the adaptations to living environment and the chemical compositions of Betula davurica Pall leaves collected in Heilongjiang, Jilin and Liaoning areas, by using scanning electronic microscopes.The result shows that the shapes, amounts and cuticle of the epidermal forms of leaves from different areas have different adaptive features.The composition of microelements in these leaves are also different.

Key words: Betula davurica Pall, epidermal characters of leaf, chemical composition
