住宅区：文华园的3个样地和瑞士花园的2个样地。主要交通干道：大学路的3个样地和民族大道的2个样地。商业区：以人面子为主要街道树的新民路，以红桂木为主要行道树的新竹路，以中国无忧花为主要行道树的圆湖路。调查结果表明：在南宁市四个功能区的24个绿化样地，主要的绿化乔木有 45种，前 10种依次是：人面子、假摈梆、垂叶榕、桂花、扁桃、蒲葵、阴香、马尾松、芒果和中国无忧花，主要的绿化灌木有24种，前8种依次是九里香、尖叶木犀揽、黄叶假连翘、扶桑、花叶朱蕉、紫蒲、短穗鱼尾葵和大花美人蕉，这些植物基本上代表了本市绿化植物的主体。

On the basis of the results obtained in the present study, the opinion on bamboo evolution were proposed:(1) Bamboos are monophyletic group,(2) Unicaespitose bamboo are not the original bamboo group,(3) Bamboos of genus Arundinaria are multiphyletic group, and (4) Bamboos of genus Phyllostachys are multiphyletic group.

同时对竹类植物分类系统提出新的看法：(1)在目前生殖体特征仍不完全的情况下，以地下茎为基础建立竹子分类系统或对现有分类系统进行修订是合理的，需要对地下茎进行更为详尽的研究并辅以地上秆的高度等方面的信息；(2)青篱竹属复合群中的现有划分方法可依据分子进化研究的结果作适当调整，如可依据MOC1分析的结果划分为低矮灌木、较高灌木和乔木3种类型。

The changing climate first affects the structure of alpine timberline at an autecological level, and further affects the movement of the timberline as a whole.

气候变化首先从个体的水平影响林线的内部结构，然后才影响到作为整体的林线的推移，因此研究乔木个体生理活动与气候条件之间的关系，对于研究高山林线对气候变化的响应具有重要意义。

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。

The selection of Paulownia fortunei, Ulmus Pumila, Broussonetia papyrifera and Cynodon dacytlon in that serious pollution district was the effective restorative method.

因而在Cd、Pb和Zn严重污染的环境中，选择泡桐、白榆、构树和狗牙根的乔木和草本植物组合是该类污染区植物修复的有效途径。

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.
