For modern residence, plant community is foundation of green space environment, plant sight is main part of green, so arbor, shrub, herbage flower, liane should be organic combined, in terms of the comparability of their kinds and habit makeup rich arrangement but no miscellaneous, adapt to man power gardens plant community with nature environmental condition in that place, to bring into play the best ecological benefit.

现代的住宅小区，植物群落是绿色空间环境的基础，植物景观是绿色的主体，因此，应以乔木、灌木、草本花卉、藤本植物来有机结合，根据它们的种类和习性的相似性组成层次丰富而不芜杂，适合该地自然环境条件的人工园林植物群落，以发挥最佳生态效益。

Podocarpus nagi are the least.(5) Comparing the plant communities from different latitudes, it shows that the rule of community species diversity and community tree layer diversity index change as the latitude changes according with Wlater and Whittakers conclusion about Shannon-Wiener index decrease as latitude increase.

5与不同纬度的植物群落的比较结果表明：群落物种多样性和群落乔木层多样性指数随纬度的变化规律符合Wlater和Whittaker关于Shannon－Wiener指数随着纬度的升高而降低的结论，即与群落物种多样性的纬度趋势一致。

青岛市城市森林建设的树种近自然化规划：树种布局规划应以树种调查、分析、评价为基础，以城市生态学、生态园林学、风景美学、城市规划学等理论为指导，并综合青岛市所在植被分布自然规律和城市森林建设现状，因地制宜的确定城市树种的主要比例关系：常绿树与落叶树的比例以3：7为宜；乔木与灌木的比例以2：1为宜；针叶树与阔叶树的比例以1：4为宜；木本植物与草本植物之比1：4；速生树与慢生树的比例以1：1为宜。

The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.

高大建筑物、乔木及灌木遮荫会使用于城市绿化的草坪草受到严重胁迫，造成草坪草衰退，针对这一难题进行了研究；以耐荫性不同的冷季型草坪草匍匐紫羊茅派尼、草地早熟禾肯塔基、匍匐翦股颖摄政王为试验材料，研究了不同浓度的外源激素稀效唑(Uniconazole， S3307)处理对3种遮荫草坪草生理及生长变化的长期调控作用；经稀效唑处理，3种草坪草叶片叶绿素含量和可溶性糖含量增高，植株株高变低，叶片变宽、变厚，不同耐荫性草坪草的耐荫能力均得到显著提高，最适的处理浓度范围100~200mg/L；这在生产实际中有重要应用价值，特别对提高受遮荫胁迫的草坪质量具有重要意义。

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。

Any of various trees and shrubs of the genus Casuarina having jointed horsetaillike stems and whorls of scalelike leaves; some yield heavy hardwood.

Cephalomappa sinensis is a monotypic genus ever-green tree endemic to the calcareous mountainous region in southwest of Guangxi Zhuang Autonomous fresh branches are used as feeding stuff for cattle,horse,sheep,and can make them find the possibility of developing feed additive or medicine for livestock,the chemical constituents from this plant were chemical constituents of its roots had been reported in our earlier continuation of our investigation on the branches of Cephalomappa sinensis,a new norneolignan,named Ceplignan(1),was isolated from ethanol extract through column structure was elucidated on the basis of spectroscopic evidence.

肥牛木(或称肥牛树，Cephalomappa sinensis)为大戟科一单种属植物，为常绿乔木，其分布区狭窄，仅限于广西西南部石灰岩山地[1]。肥牛木为优良木本饲料树种，是牛、马和羊的好饲料，用该植物饲养牛，可使牛肥壮，故有肥牛木的名称[1]。研究其化学成分，目的在于探讨开发饲料添加剂或兽药的可能性。我们曾报道了肥牛木根的化学成分[2，3]，在对其枝条的进一步研究中，又分离得到一个新的降新木脂素，命名为肥牛木素。本文报道其分离方法和结构鉴定结果。

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。
