Abstract:

Base on the investigation on fast-growing, and high-yield character, site adaptability, and economic character of ten broad-leaved tree species grown in Fujian Province, 10 broad-leaved trees species were evaluated by the method of polygonal decision. The results showed that among 10 tree species, the evalution value of fast-growing and high-yield was highest in Sassafras tsumu, and that of economic character was highest in Phoebe bournei, and for the adaptability index,Cyclobalanopsis chungii, Castanopsis hystrix, and Castanopsis kawakamii were best. 10 tree species could be divided into three grades. The Castanopsis hystrix and Phoebe bournei were in the first grade, which were the suitable tree species for planting in Fujian Province. Sassafras tsumu, Castanopsis kawakamii, Cinnamomum micranthum and Cyclobalanopsis chungii were in the second grade.

Key words: Broad-leaved tree species, Fast-growing and high-yield, Polygonal decision
