| Abstract: | Combing clear-cutting of natural forests,broad-leaved trees and seed-trees of Pinus massoniana was planed to retain,a few good stay broad-leaved trees were raised,Cunninghamia lanceolata was cultivated to grow mixed coniferous.After C.lanceolata of 1 generation was harvested,using stump sprouts for nurturing C.lanceolata of 2 generations,mixed forests of coniferous and broad-leaved trees were continue operated.Through long-term management and cultivation,now the mixed forests of coniferous and broad-leaved trees composed of P.massoniana,Castanopsis trees,Liquidambar formosana,Alniphyllum fortunei and other broad-leaved trees,the average height of these species was 12 ~ 18 m,the average DBH was 15.7 ~ 26.2 cm,the average stumpage was 125 plants per 667 m2,the average accumulation was 13.496 m3/667 m2,the average canopy density was 0.75. |
