Forest are studied. The forest component is composed mainly by the families Fagaceae , Euphorbiaceae

纳热带山地的季风常绿阔叶林主要由壳斗科、大戟科、茶科和樟科等树种组成；乔木树种种

Davidii forest, while arbor layer could be divided into two sub-layers, with a height of 4.05-7.86 m for the upper layer, and of 2.05-3.20 m for the lower layer. In the community, there were 32 herbal species belonging to 27 genera of 13 families and dominant by Poaceae, Fabaceae and Compositae, and 11 areal types, among which, the species number in Mongolian-Northeastern China-Dahuricia-North China areal type was the highest (34.38%), followed by that in Northeastern China-North China areal type (12.5%).

结果表明：研究区刺榆林不存在灌木层；其乔木层可划分为2个亚层，上、下层高度分别为4.05~7.86和2.05~3.20m；林下共有32种草本植物，隶属13科27属，以禾本科、豆科和菊科为主；研究区有11个植被分布区型，其中，蒙古－东北－兴安－华北分布区型种类最多(34.38%)，其次为东北－华北分布区型(12.5%)。

Is an ever-green broadleaved tree of Fagaceae, widely distributed over the subtropical area of China, also distributed in Japan, India, Korean and Burma.

青冈是壳斗科的常绿乔木，地理成分属于东亚分布的中国-日本变型，广泛分布于我国亚热带地区，在日本、印度、缅甸等国也有分布。

Fagaceae and Theaceae are the dominant families, with the RBA value being 60.1% and 12.2%, respectively. The Shannon Wiener index of the tree layer is about 3.0. The indicies of H ′ and Pielou evenness index both increased with sampling area, and stabilized at 1500 m 2 and 1000 m 2, respectively.

多样性分析结果表明，乔木层Shannon-Wie-ner指数为3.0左右；随着取样面积的增加，H'值和均匀度指数逐渐增加；1500 m2时H'趋于平稳，1000m2时E趋于平稳。

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.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
