摘　　要：本文从种间关系、林分结构、混交效益等方面对造林9年的杉木分别与金钱松、湿地松,檫树柏木、花榈木树神混交的初步评价。提出金钱松、檫树,湿地松与杉木混交,能提高单位面积产量,且能不同程度的维持地力,是杉木较好的伴生树种。柏木与杉木混交,能成林,但对恢复地力,提高生产率作用不大。花榈木不适宜作杉木的伴生树种。Preliminary estimations on 9-year Chinese fir (Cunninghamia lanceolata) forests mixted respectively with Golden Larch (Pseudolarix kaempferi), Slash pine (Pinus elliottii), Sassafras (Sassafras tsumu), Cypress (Cupressus funebris), Henry ormosia (Ormosia henryi) were introduced by interspecieses relation, stand composition, mixture efficiency, etc.. Chineses fir forests mixted with good axiliary species such as Golden Larch, Sassafras and Slash pine could increse yield per unit area and maintain soil power in varying degrees. Chinese fir mixed with Cypress could form forest but could not contribute to regain soil power and increase productivity. Henry ormosia was inconvinient to be axiliary tree with Chinese fir.
