And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

Under disturbances, original tropical seasonal rainforest has been replaced by several secondary vegetations experiencing progressive succession among which Sterculia nobilis pure forest and mixed forest of S. nobilis and Pteroceltis tatarinowis are best flourished.

但现存植被则是原生植被受不同程度干扰后形成的多种次生植被类型，且都处于向上演替的过程之中，保存最好的是苹婆纯林及其与青檀组成的混交林。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
