【摘要】 应用平均标准木法和样方收获法对凹叶厚朴杉木混交林各经营模式林分的生物量、生物量组成及分布的研究结果表明：不同经营模式的林分中，以行间混交的生物量及生产力最高， 分别为７４．９６ ｔ／ｈｍ ２ 和６．２５ｔ／ （ ｈｍ ２·ａ）； 混交林各经营模式的营养空间分布均比杉木纯林合理，对林木生长有促进更多还原

【Abstract】 The biomass,biomass composition and its allocation in different stand of the mixed Magnolia officinalis var Biloba and Cunninghamia lanceolata forest were studied, by using the methods of “method of mean sample tree”and “quadrat harvesting method” The results showed that the biomass and productivity of line mixture stand by Magnolia officinalis var Biloba and Cunninghamia lanceolata were the highest than other stands, which were 74 96t/hm 2 and 6 25t/(hm\+2\{a) \}The spatial distribution of mixed stands, which was helpful to the growth of stand, was more rational than the pure stand of Cuuninghamia lanceolata更多还原
