Canopy structure, light distribution and leaf biomass of tussah-feeding oak forest

Abstract

Abstract: Tussah-feeding oak forest is a unique coppiced forest ecosystem. In a long period of management, different canopy forms are artificially established. There practically exist three types of canopy forms. Comparative studies are conducted in canopy structure, light distribution within crown and leaf biomass for three oak species. The results show that among the three types of canopy forms, form A (the "Stair" form) has the advantages in higher leaf area index, more reasonable of leaf distribution pattern and the highest leaf biomass. The other two types have no significant difference in leaf biomass. But form B (the "Tree" form) is better than form C ("Shrub" form) for its larger crown, lower coefficent, of light extinction and better light environment within crown.

Key words: Tussah-feeding oak forest, Canopy structure, Leaf biomass
