摘要
通过对常绿阔叶林迹地两种更新方式所形成的不同群落生产力的比较研究，结果表明：采用人促天然更新形成的米储单优群落生产力与经济效益均高于杉木人工林，其中米储单优群落的林分总蓄积量比杉木林高１１．８７％，林分总生物量高２２．１０％；人促天然更新的投资利润率和财务内部收益率分别比营造杉木人工林高５．８４％和１１．０３％。
The results indicate that（1）the Productivlty and economic benefit of Castanopsis carlesiiconsociation formed by the natural reproduction with artlficial promotion are higher than those ofCunninghamia lanceolato plantation，of which the total stand stock of C. carlesii consociation is 11．87％higher than that of C. lanceolata stand and the total stand biomass of the former is 22．10％higher than thatof the latter： and（2）the investment profit rate and financial internal income rate of the natural reproductionwith artificial promotion are 5．84％and 11．03％than those of the planting of C. lanceolata plantation.respectively.
