山茶科

The richness center of the Theaceae plant species under study is located in the mountainous area of north Guaugdong (22.5°N, and 112~115°E). These plants species exhibited significant longitudinal difference (P=0.0012), and latitudinal variation (P=0.0049). Canonical Correspondence Analysis showed the distribution of plant species could be explained by caloric factors and moisture factors, and MAMI (mean annual minimum temperature) was the key factor determining the distribution pattern of Theaceae plant species richness in the study area.

对125种植物、72个网格和6个环境因子进行典范对应分析表明：CCA排序轴第1轴主要代表温度的变化梯度，第2轴主要代表水分的变化梯度，说明水分、温度等因素共同影响山茶科植物在广东的生长和分布，其中年均最低温度是影响广东省山茶科植物丰富度水平地带性格局的最大因子。

Salicifolius; the columella is clear with few perforation in exine. Pollen characters do not support two sections below Stachyurus, but can be used as important characters in the species taxonomy. They also do not

此外，对旌节花科和Crossosomataceae花粉表面纹饰和外壁超微结构的研究结果提示：这两个科与省沽油科和山茶科厚皮香亚科有较近缘的关系，而不支持这两个科的姐妹群关系。

However, the taxa of strictly tropical distribution are still underrepresented in the flora of southeastern Yunnan compared to Indo-Malaysian flora, and the families of mainly subtropical to temperate distribution, such as Magnoliaceae, Theaceae, Cornaceae, Styracaceae, Symplocaceae, Aquifoliaceae and Caprifoliaceae, are well represented in the flora. Some characteristic families of temperate East Asia, such as Diapensiaceae, Dipentodontaceae, Eupteleaceae, Grossulariaceae and Toricelliaceae are also present in the flora of southeastern Yunnan.

由於位於东南亚热带北缘山地及其地质历史原因，云南东南部的热带植物区系中严格热带分布的成分不多，仍以边缘热带成分为主，并有相对丰富的亚热带－温带科如木兰科、山茶科、山茱萸科、山矾科、忍冬科、冬青科等以及一些东亚和喜马拉雅特徵科，如岩梅科、十齿花科、领春木科、茶藨子科和鞘柄木科，显示了它与东亚温带植物区系也有较多联系。

The dominant families or the characteristic families are Theaceae, Aquifoliaceae, Fagaceae, Caprufoliaceae、Lauraceae、Vutaceae、Compositae、Myrsinaceae、Araliaceae、Euphorbiaceae、Eriaceae、Moraceae、Rubiaceae, and most of them are of tropical-subtropical distribution.

本区系的优势科或表征科是山茶科、冬青科、壳斗科、忍冬科、樟科、葡萄科、菊科、紫金牛科、桑科、五加科、大戟科、杜鹃花科、桑科、茜草科，绝大多数是热带亚热带分布的。

The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.

摘要运用样方法对贵州省玉舍国家级森林公园稀有保护植物十齿花群落的物种多样性进行了研究，结果表明：玉舍国家级森林公园十齿花群落以蔷薇科、杜鹃花科、壳斗科、桦木科、山茶科、樟科、忍冬科、山茱萸科等为优势科；10个样地中有8个样地以十齿花种群占绝对优势，其平均重要值高达135.69，远远高于其它种群；十齿花群落乔木层物种丰富度为2.847、Simpson指数为0.601、Shannon-Wiener指数为1.523、种间相遇机率为0.601、均匀度指数为0.569，总体上均小于灌木层(分别为：5.580、0.830、2.377、0.829、0.672)，表现为较明显的亚热带常绿落叶阔叶混交林的物种多样性特征。10个样地中，Q1的物种多样性程度最高，Q3次之，Q5和Q6最小，多样性程度最低，10个样地的物种多样性排序为Q1＞Q3＞Q9＞Q7＞Q2＞Q4＞Q10＞Q8＞Q5＞Q6。

Results of sampling showed that the typical evergreen broad-leaved forest of Mt. Jiulianshan consisted mainly of subtropical families and genera with dominant families including Fagaceae, Lauraceae, Camelliaceae, Styracaceae, Ericaceae, and Magnoliaceae.

群落主要由热带、亚热带科属组成，优势科为壳斗科Fagaceae，樟科Lauraceae，山茶科Camelliaceae，安息香科Styracaceae，杜鹃花科Ericaceae和木兰科Magnoliaceae等科，优势树种以相应的优势科属树种为主。

In habitats of the broad-leaved forest, the dominant tree are the species of Fagaceae in tree layer, Theaceae, Saxifragaceae and Lauraceae in shrub layer, Cyperaceae, Dryopteris spp. and Liliaceae in herb layer.

在阔叶林型栖息地中，乔木层主要树种为壳斗科植物，灌木层植物以山茶科、虎耳草科和樟科等科的种类为主，草本层植物以莎草科、蕨类和百合科为主。

The dominant families included Lauraceae, Magnoliaceae, Fagaceae, Theaceae and Ericaceae.

其中优势科主要有樟科、木兰科、壳斗科、山茶科和杜鹃花科。

Most of the secondary forests in Zhuhai are dominated by the species of Lauraceae, Euphorbiaceae, and Theaceae. There are also many tropical taxa of Rubiaceae, Myrtaceae, and Moraceae.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
