| 中文摘要: |
| 通过采集云南松不同径阶的150株样本，对比分析其不同径级组间和不同径级组内各部位生物量占比情况。研究表明：不同径级组间径级组越大，树干生物量占比越高，树叶生物量占比越低；树枝、树根生物量占比随径级组增大先增高后降低，中径级组占比最高；地上部分生物量占比随径级组增大先降低后增高，中径级组最低。不同径级组内树干生物量占比占绝对优势，均达到一半以上，其它部位生物量占比均未达到20%。 |
| 英文摘要: |
| 150 samples of Pinus yunnanensis from different diameter classes were collected to compare and analyze the proportion of biomass in and within different diameter groups. The results showed that the larger the diameter group, the higher the proportion of trunk biomass, the lower the proportion of leaf biomass; the proportion of branch and root biomass increased first and then decreased with the increase of diameter group, and the proportion of medium diameter group was the highest; the proportion of aboveground biomass first decreased and then increased with the increase of diameter group, and the proportion of medium diameter group was the lowest. The proportion of trunk biomass in different diameter groups was absolutely dominant, reaching more than half, and the proportion of biomass in other parts was less than 20%. |
