| 摘 要： | 通过选定同乐林场米老排林分作为研究对象,采用样地调查与解析木对该树种进行生长特性研究。结果表明:0~6年是米老排幼林生长的阶段,树高、胸径生长均较为旺盛,6~12年材积与胸径生长迅速,而树高生长速度呈现下降趋势,12~16年是米老排生长树高、胸径、材积这三个指标的速生时期,28年以后树高生长速度逐渐下降,材积与胸径生长还呈现上升趋势。米老排的单株和林分生物量排序为干枝根皮叶。

Study on growth laws and biomass distribution pattern of Mytilaria laosensis |

| Abstract: | Through survey to the growth regularity and biomass structure of Mytilaria laosensis forest stand in Tongle State-owned Forest Farm of Guangdong Province,and stem analysis of sample trees to turns out that the general growth pattern of M. laosensis is as follow:the height,DBH and volume of M. laosensis all increase with age:0~6a is growth stage of young stand and the increase of height and DBH is comparatively fast;in 6~12a,the volume and DBH increase rapidly but tree height growth shows a downward trend;12~16a is the surging growth period of the three indexes of M.laosensis:tree height,DBH and volume;After 28a,growth speed of tree height gradually decreases but the growth of volume and DBH still presents a rising tendency. The biomass of each single tree and M. laosensis stand are sorted into:trunk >branch >root >bark>leaf. |
