摘　　要：通过对红皮云杉培育过程中投入成本和产出的统计整理,运用内部收益率(IRR)指标进行分析比较,结果表明:内部收益率与地位指数密切相关,随着地位指数升高而增加,最适宜在14、15两个地位指数级;红皮云杉低密度短轮伐期培育用材林的内部收益最高。Based on the statistics of the input cost and output in the cultivation process of Picea koraiensis,the internal rate of return(IRR)index was used to analyze and compare.The results showed that the internal rate of return was closely related to the position index,which increased with the increase of the position index,and was most suitable for the 14 and 15 position index levels;The internal income of Picea koraiensis low density short rotation cultivation timber forest is the highest.
