The larger the niche overlap of two species is, the more similarly resource space they occupy. the niche overlap of Leontopodium leontopodioides and Polygonum viviparum amounts to 0.892 (in the community Ⅰ). This proves that they are very similar in utilizing the resources. In the general community, the niche overlaps among species are very low.

两个种群的生态位重叠值越大，说明它们占据越相似的资源空间，珠芽蓼和火绒草的生态位重叠值高达0.892，说明它们利用资源的相似性程度很高；在总群落中，各种群之间生态位重叠值都很低。

Fluorescence in situ hybridization with 16S rRNA-targeted oligonucleotide probes was applied for analyzing the community of iron bacteria in wastewater from the Shengli Oil Field. Four 16S rRNA probes were designed, which were highly specific to iron bacteria Leptothrix, Sphaerotilus, Leptospirillum ferrooxidans, Leptospirillum ferriphilum and Acidithiobacillus spp.

根据油田外排水中常见铁细菌的16SrRNA特异性保守序列，设计和合成了4种荧光探针，利用荧光原位杂交方法，分别利用它们对胜利油田孤岛采油厂、胜利采油厂1号和2号综合处理站外排水中存在的铁细菌的种类和数量进行检测，分析了各外排水中铁细菌的群落结构。

The Institute was established in 1952 and carries out complex limnological studies on streams, rivers, and reservoirs with special attention to the structure of biocoenoses, relations between aquatic organisms and physico-chemical factors of their habitats, and anthropogenic alterations in inland-water ecosystems.

该研究所成立于1952年。主要致力于河流、水库的湖沼学研究，侧重研究生物群落结构、水生生物与其栖息地物化因子间的关系、以及内陆水域生态系统的人类起源等。

Phragmites Australis, Ael uropus liitoralis, Zoysiamacrostachya, Messerschmidia sibirica, Limonium bicolor were the main vegetation types in the chenier seaside, but in the chenier plain, Artemisia annua, Artemisia mongolica and Herba Heteropappi Altaici occurred frenquently.

通过对无棣贝沙堤植物多样性的分析发现，样方内共出现物种20余种；同时，贝沙堤向海面和贝壳滩脊、向陆一面分别分布着以芦苇、獐茅、大穗结缕草、二色补血草、砂引草以及以青蒿、蒙古蒿、阿尔泰紫菀为优势种的群落。

The results showed that the Shannon-Wiener and Levins′s niche breadths of Schima khasiana,Lithocarpus hancei,Lindera fruticosa,Salix magnifica and Myrsine semiserrata tree species were 0.772,0.761,0.741,0.659,0.632 and 0.971,0.934,0.843,0.708,0.658 respectively.

结果表明：群落中生态位宽度较大的树种为印度木荷、硬斗石栎、绿叶甘橿、贡山大叶柳、针齿铁子，它们的Shannon-Wiener和Levins生态位宽度分别为0.772，0.761，0.741，0.659，0.632和0.971，0.934，0.843，0.708，0.658。

The results showed that the vertical structure of Lithocarpus glaber forest was rather complicated, and could be divided into arbors layer, shrub layer, herbaceous layer, and interstratum plants.

结果表明，石栎群落垂直结构较为复杂，可分为乔木层、灌木层、草本层，亦有少量的层间植物。
