Based on the status of suburban forest of Harbin, 49 well-grown afforesting tree species including 32 species arbor, 16 species shrub and only 1 species vine which are mainly Pinus sylvestris var. mongolica, Betula platyphylla, Syringa oblata and Acer negundo et al, were selected in this study. An information system concerning tree species was established by sorting qualitative index, testing quantitative index as well as referring to other study results.

Between shrub and herb layers ,the difference of each index was not significant The total richness index and Shannon-Wiener index of Phellodendron amurense plantation community were all the highest than those of the other communities.(2) The total richness index of Machilus pingii- Quercus oxyodon evergreen broad-leaved forest community, Alnus cremastogyne-Betula luminifera-Quercus oxyodon evergreen-deciduous broad-leaved forest community and Rhus potaninii- Juglans sigillata- Quercus oxyodon evergreen-deciduous broad-leaved forest community all exceeded 31 .These communities , the dominance species in their shrub layers is Fargesia rufa ,such as Betula luminifera-Rhus chinensis-Quercus oxyodon evergreen-deciduous broad-leaved forest community, Quercus oxyodon-Litsea pungens-Cornus macrophylla evergreen-deciduous broad-leaved forest community, Cornus macrophylla- Acer caudatum var.

2润楠-曼椆常绿阔叶林、桤木-亮叶桦-曼椆常绿落叶阔叶混交林、青麸杨-野核桃-曼椆常绿落叶阔叶混交林群落的总体丰富度指数均大于31；在灌木层以青川箭竹为主的群落(亮叶桦-盐肤木-曼椆常绿落叶阔叶混交林、曼椆-木姜子-梾木常绿落叶阔叶混交林、梾木-川滇长尾槭-落叶阔叶林、川西樱桃-尾叶樱-川滇长尾槭落叶阔叶林)中，各群落总体丰富度指数和Shannon-Wiener多样性指数较小，总体优势度指数较大；8种次生林群落灌木层丰富度指数均高于乔木层，乔-灌层间丰富度指数差异性检验达显著水平；乔-草层间的丰富度指数差异性检验达极显著水平，Shannon-Wiener多样性指数差异达显著水平；灌-草层间的多样性指数和优势度指数差异性检验均达显著水平。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

Results indicated that Hoolock gibbons tended to inhabit eastern slopes E(subscript i= 0.344 as they were relatively windproof. They also favoured the tree species Querucus acutissima E(subscript i=0.455 and Eurya pseudocerasifera E(subscript i=0.068 for their large crown, as they provide more continual movement routes and large spaces for the gibbons, compared with other plant species.

定性因子分析表明，白眉长臂猿偏爱在东坡E(下标 i=0.344活动，可能与其能提供避风的温暖微生境有关；偏爱栓皮栋E(下标 i=0.455和拟樱叶柃E(下标 i=0.068等乔木，可能是由于这些树种的树冠面积大，可为白眉长臂猿提供连续的移动路线和大的活动空间。

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。
