| 摘 要： | 在调查杉木与乳源木莲混交林及杉木纯林(对照)生长量的基础上,进一步分析了杉木与乳源木莲混交林及杉木纯林地上部分各器官及各径级根生物量分配格局。研究结果表明,杉木与乳源木莲混交林中杉木的生长及林分总生物量的积累均优于杉木纯林。从生物量分配上看,杉木与乳源木莲混交林中杉木及纯林中杉木其地上部分各器官的分配均表现为树干>叶>枝,但混交林中杉木叶和干分配率略大于纯林,而枝分配率略低于纯林;混交林中杉木各径级根的生物量均大于杉木纯林。

| Abstract: | Based on the investigation of growth of Cunninghamia lanceolata and Manglietia yuyuanensis mixed forest and C. lanceolata pure forest(control), the biomass of different above-ground organs and root distribution patterns were studied in this paper. The results showed that the growth of C. lanceolata and total above-ground biomass were higher than those of C. lanceolata pure forest. As far as the biomass distribution patterns were concerned, the biomass distributions of different organs were trunk>leaf> branc... |
