In the plant vegetations are mainly communities, the niche breadths vary greatly and the similarity ratios among different plants are very low.

植物群落内生态位宽度悬殊，植物种之间的生态位相似比例很小。

The niche breadths of same plants vary greatly among different communities and the competitive relations of the plant species in different communities vary depending on the combined actions of the niches of the species, stable landforms and soil conditions, and annual rainfall fluctuations.

同一种植物在不同群落中的生态位宽度变幅较大，不同群落内部植物种竞争关系的差异是由物种的生态位和由相对稳定的地貌、土壤条件以及随年际变动的降水条件共同作用的结果。

Niche breadths of most native populations in natural forest were wider than that of P. armandii forest. Furthermore, competitions among populations were not so strong, and community structure was more stable, because of great niche differentiation in natural forest.

天然林中大多数乡土树种的生态位宽度较之在华山松林中大为增加，但由于长期协同进化，种间生态位分化程度高，种间竞争较缓和，群落具有很高的稳定性。

For policy of green environmental protection coming into operation, recent point is that EuP (Eco-Design Requirements for Energy Using Products) proclaimed by European Union on July, 2005 and bring into operation from May, 2008. Eco-design Requirement for Energy Using Product leads to raise efficiency of product energy in environment.

对於绿色环保政策的实施，目前的重点则是欧盟另一项於2005年7月公告的EuP(能源使用产品生态化设计指令)，并於2008年5月之后实施，是藉由规范能源使用产品的生态化设计要求，以提高产品的能源效率及环境绩效。

Evergreen broadleaf tree is the principal part of fore stry reserves and the most important component of forestry ecosystem.

常绿阔叶林是南方森林资源的主体，是森林生态系统中重要的组成部分，可改善人类生态环境。

In the process of bryophyte community formation, the random process,nature of colonization, and difference in regeneration strategy can result in the niche overlap and coexistence of bryophytes, and the niche differentiation res

随机过程、物种的殖民本质以及更新策略的差异可导致苔藓植物生态位的重叠与共存，但竞争导致生态位分化也是苔藓植物共存的机理之一。

In the process of bryophyte community formation, the random process, nature of colonization, and difference in regeneration strategy can result in the niche overlap and coexistence of bryophytes, and the niche differentiation resulted from competition is also one of the mechanisms for bryophytes coexistence.

多种苔藓植物间可存在竞争等级，该等级往往随环境的变化而变化。随机过程、物种的殖民本质以及更新策略的差异可导致苔藓植物生态位的重叠与共存，但竞争导致生态位分化也是苔藓植物共存的机理之一。

It is also argued that, in order to realize these picture, the anti-planning methodology which emphasizes the planning of unbuidable land, instead of buildable land, is critical.

"反规划"就是规划和设计城市生态基础设施，并提出城市生态基础设施建设的景观安全格局方法。

These strategies are ways to establish an ecological infrastructure for the sustainable urban development in the future of centuries to come. It is also argued that, in order to realize these picture, the anti-planning methodology which emphasizes the planning of unbuidable land, instead of buildable land, is critical.

为此，文章提出了"反规划"概念，即城市规划和设计应该首先从规划和设计不建设用地入手，而非传统的建设用地规划，"反规划"就是规划和设计城市生态基础设施，并提出城市生态基础设施建设的景观安全格局方法。

"Bio2 is a synthetic ecosystem, but so is California by now," said Burgess.

"生物圈二号是一种合成的生态系统，而现在的加利福尼亚也是一种合成的生态系统。"

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
