Study on C, N, P Content in Leaf of Evergreen and Deciduous Trees in Evergreen Broad-leaved Forest at E'mei Mountain
Study was made on C, N, P content in leaf of evergreen and deciduous trees in evergreen broad-leaved forest at E'mei Mountain, Sichuan province and relationship among them. The result showed that mean content of C, N, P in evergreen species was respectively 42.30%, 1.46% and 0.10%, while that in deciduous one was 41.078%, 1.59% and 0.12%. N content in the tested forest leaves had close relation with P content, while no evident relation between C and N, C and P. The average N and P ratio in leaf from evergreen species was 14.48 and 13.61 from deciduous ones, indicating low adaptive faculty to local ecological environment.
