【摘要】 本文以双重抽样和相对变比生长模型(y=ax^be^cx)测定米槠人工林在疏开状态下的生产量。10年生米槠林分生物量为72.317t·ha^-1,其中乔木层、灌木层和草本层分别为71.404、0.305和0.606t·ha^-1,乔木层占98.74％;乔木层中树干（包括树皮）、树枝、叶和根系的生物量分别为26.410、24.170、7.413和13.411t·ha^-1,树冠生物重占44.23％,产生较大的倾斜分配。林分叶面积指数为5.478m²/m²,林木现存单株生物量达到166.45±62.55kg。林分生长质量好,Ⅰ级木生物量占47.77％。更多还原

【Abstract】 This paper studies the biomass of Castanopsis carlesii plantation of 10-year-old by means of variable allometric ratios and double sample.The result shows that biomass of open-stand is 72.317t/ha, the biomass of crop, shrud and herbaceous are 71.404, 80.305 and 0.606t/ha, respectively. The crop holds 98.74% for its stand biomass. Biomass of stem ( and barks), branch, leaves and root are 26.410, 24.170, 7.413 and 13.411t/ha, respectively. Leaf area index of the stand is 5.478m2/m2. Biomass of individual trees comes up to 166.45 ±62.55(X±S)kg/tree.更多还原
