Comparison on biomass in different parts of Pinus armandii trunk

摘要: 通过采集650株不同径阶组华山松树干生物量样本，对比分析不同径阶组内、不同阶组间树干、木材、树皮各部位生物量占比情况。结果表明：华山松不同径阶组内，树干、木材、树皮各部位生物量占比均呈现上部最小，中部次之，下部最大；不同径阶组间，随着径阶组增大，树干、木材、树皮上部生物量占比逐渐增加，中部生物量占比变化不大，下部生物量占比逐渐减小。Abstract: By collecting 650 trunk biomass samples of Pinus armandii with different diameter levels, the biomass ratios of trunk, wood, and bark within and among different diameter levels were compared and analyzed. The results showed that the percentage of biomass of trunk, wood and bark in the upper part was the smallest, the middle part was the second, and the lower part was the largest; among different diameter order groups, with the increase of diameter order group, the proportion of upper biomass of trunk, wood and bark gradually increased, the proportion of middle biomass did not change much, and the proportion of lower biomass gradually decreased.
