群落

Communities structure, standing crops of benthic algae were investigated in the littoral zone of 6 Yunnan plateau lakes, and benthic algae communities were composed of Cladophora spp.

对云南6个高原湖泊沿岸带底栖藻类的群落结构、现存量等进行了调查，研究期间发现底栖藻类群落主要由绿藻门的刚毛藻Cladophora spp。

This paper describes the meaning and characteristics of regional developing strategies,and then with the close relevance of regions at development and biological community,the authors advocate the regional developing strategies based on biological community principles,namely industry clustery strategies and city group developing strategies .

首先对区域发展战略的内涵、特点进行描述；然后根据区域发展和生物群落的密切相关性，提出了基于生物群落原理的区域发展战略，即产业集群战略和城市群发展战略。

As for single dominant species commimity, either Halostachys caspica commimity or Haloxylon persicum commimity, the spatial pattern was all congregative pattern in 0~50m scale.

单优种盐穗木群落、白梭梭群落的优势种盐穗木和白梭梭在所研究的尺度(0～50m)上均为聚集分布。

But whether any such scheme will benefit or marginalise forest communities is a critical question, write Lorenzo Cotula and James Mayers.

然而，这种方案究竟是有利于林木群落还是使林木群落更加边缘化是一个值得我们探讨的关键问题。

These suggest that Pinus massoniana, the pioneer species at early succession stage of forest community, is the plant species adapted to high light intensity, while Cryptocarya concinna, a species at succession climax stage has an advantage in light utility under low light environment.

这说明群落早期演替的先锋树种马尾松属于强阳生性树种，具有适应强光的特点，而处于群落演替项级阶段的优势种黄果厚壳梓则能更加充分利用低光生长环境中的光强，同时也可通过提高电子流向光呼吸分配的比例来避免自然光环境中强光的伤害。

On the section, the Wenghui Biota can be redivided into Globusphyton,Sectoralga-Longifuniculum,Cucullus,Beltanelliformis,and Baculiphyca- Gesinella Communities, from below to above. The change and evolution of these communities show the relation the biota and microenvironment, and indicates the relationship macro-plants with metazoans.

在时间纵向上可依次分为Globusphyton ， Sectoralga-Longifuniculum ， Cucullus ， Beltanelliformis ，Baculiphyca-Gesinella等5个群落，反映出生物群落与环境的相关性以及宏体后生动物与植物之间的相关性和规律性。

The results showed that the human disturbance didn't change the dominant positions and roles of Pinus massoniana and Cunninghamia lanceolata in arbor. But it decreased the average diameter at breast height and average tree height and changed the species composition.

结果表明，人为干扰对乔木层马尾松Pinus massoniana和杉木Cunninghamia lanceolata优势种的主体地位和作用没有根本性的改变，但使群落平均胸径和平均树高降低，群落种类组成发生变化。

Studies on the relationship of species showed that overall association of Cunninghamia lanceolata forest was significant positive correlation and the community was at a stable stage.In 22 species,7 species pairs exhibited highly significant positive or negative association.

种问关联性的分析表明，杉木林群落总体相关性表现出显著的正相关，反映了该群落的稳定性。22个树种，具有显著正联结或负联结的种对有7对。

Manchurica, Eugonophyllum, cyanophyceae community and another is Formit-chevella community.

manchurica，叶状藻Eugonophyllum和菌藻类蓝细菌群落及珊瑚Formitchevella群落。

Based on monthly fishery resources investigation data of demersal trawl from 1986~1987 in the Pearl River Estuary and adjacent waters,the paper quantitatively analyzed variation of fish community of various species by cluster analysis and principal coordinates analysis of a package of MVSP.

根据1986~1987年珠江口及其邻近水域渔业资源的周年月份调查数据，运用MVSP软件包中的聚类分析和主坐标分析对珠江口鱼类群落的时空变化进行定量分析，描述珠江口鱼类群落的季节变化和区域变化特征，把珠江口从时空上划分为4个季节和5个水域，并与传统的划分方法作比较，讨论了这种分析结果的合理性。
