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。

Meso phanerophytes and micro phanerophytes are main composing plant of arbor synusia in the area.In synusia structure,except for the warm shrubs,frost flora all have arbor synusia,shrub synusia,herbage synusia and lichen synusia.The evergreen broad leaved meso phanerophytessynusia dominates the arbor layer .

This paper introduces the concepts of CSCW, describes the present state and discusses the problems to be solved, primarily focusing on human computer interaction, concurrency control and collaboration management. According to the research on cooperative characteristics of user actions in CSCW systems, this paper proposes a software architecture model of cooperative systems, Arbor. Its main contents include: Layered structure The Arbor model divides a cooperative system into five layers according to functional decomposition: device layer, concept layer, intention layer, cooperation layer, and computation layer. It deifies user actions and reifies the results of the actions to implement multi-level collaboration among multiple users. Multi-level collaboration obtains finegrained collaboration of the cooperative system and improves its collaboration efficiency.

本文首先介绍了计算机辅助协同工作的基本概念，着重从人机接口，并发控制和协同管理等功能方面介绍了协同系统的现状及其软件结构存在的问题，然后，基于对协同系统中用户动作的协同需求和协同特性的研究，针对目前协同软件系统存在的问题，提出了一种协同系统软件结构模型Arbor，它的主要内容包括：层次结构 Arbor模型从功能上将协同软件系统分为五层：设备层、概念层、意图层、协同层和计算层，它通过对用户动作的多层抽象和对动作结果的多层例化，实现多用户之间的多层次协同及感知，层次结构增强了系统的灵活性和适应性，方便了系统的开发，同时，多层次协同的方法获得了细粒度的协同感知，提高了协同效率。

However remarkable impacts were observed in the plantation in terms of community physiognomy,community structure,species composition,species richness,and biomass accumulation.1 Planting trees made community structure simple.Betula alnoidis plantation had three layers including a dominant arbor layer,a complex and well developed shrub layer and a poorly developed vine layer.The arbor layer contained few species and had a single layer.The mountain rain forest had 4 layers including the dominant arbor layer,shrub layer,grass layer and vine layer.The vine layer was well developed and very rich in species composition,and the arbor layer contained as many as 38 species that could be grouped into 3 layers.2 Sequenced by the important value,main species for the plantation and the nature forest were totally different,and the plantation had one dominant species while the nature forest contained many dominant species.3 Planting trees changed the community physiognomy.

但是人工种植西南桦林对群落的季相外貌、群落的结构、物种组成、物种丰富度以及生物量等方面有较大的影响。1人工造林使得群落结构简化，西南桦人工林的层次结构有3层，以乔木层占优势，并且有种类多而发达的灌木层，同时，藤本植物欠发达，但是乔木层树种单一，明显仅有一层；山地雨林的层次结构有4层，以乔木层占优势，还有灌木层、草本层和藤本植物，藤本植物种类多，十分发达；乔木层树种丰富，可达38种，乔木层还可分为3层。2人工造林较大程度地改变了群落的物种组成，根据重要值的大小排列，人工林和天然林的主要物种组成已经完全不同；并且人工林单优树种明显，而天然林就含有较多的优势树种。3人工造林改变了群落的外貌。
