摘要 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木,建立数学模型,估测各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。 Platycladus orientalis and Pinus tabulaeformis are the most important tree species in limestone mountains region. The method used here is to choose the single-species wood to build the math model to measure the biomass per hectare. By using Area Proportion Method to measure the biomass of shrub and herbaceous plant under the tree, the biomass of arbor layer and shrub-herbaceous layer from the interblending trees and single-species wood was calculated and analyzed respectively. It showed that the biomass of arbor layer and shrubherbaceous layer from the interblending trees was lower than single-species wood respective- ly. The total biomass, however, of the interblending trees was far higher than single-species wood, which suggested that the policy makers take the interblending trees as the way to afforest in calcareous mountains.
