<正>采用森林收获法中的平均木法，在石灰岩山地侧柏和油松各组的混交林和纯林中分径级对等地选择标准本，建立数学模型，估测备标准地每公顷林分的生物量；在灌木和草本植物中利用面积比例的方法，测定不同林分中灌草层的生物量。同时分析了石灰岩山地中混交试验林及其纯林中乔木层和林下植物的现存生物量状况。结果表明：混交林中乔木层生物量小于侧柏纯林和油松纯林的生物量；混交林中灌草层的生物量小于侧柏纯林和油松纯林的生物量；然而混交林的总生物量大于侧柏纯林和油松纯林的总生物量。

The wood physical properties of Bambusa wenchouensis were studied and compared with those o{ other bamboos including PhyIlostachys edulis. The result showed that the basic density of B. zvenchouensis was 0.618g/cm3, lower than that of P. edulis (0.765g/cm3) and equal to or higher than that of other sympodial bamboo species. The air dry volume shrinkage ratio was 7.7%, the maximal swelling ratio was 18.686%, and the maximal water absorption ratio was 77.8%, which were all higher than those of P. edulis.
