At the same time, the biomass of species-rich community was more sensitive to the change of environmental conditions, while communities with fewer species had a little change in biomass.2 There were a total of 87 vascular plant belonging to 27 families and 68 genus in the six communities. Most species had a narrow distribution and a lower local abundance, while few species had a wider range and higher local abundance, and this distribution trends varied in different communities. The endemics were positive correlation to y diversity.

物种丰富的群落生物量对环境条件的变化敏感，较过去显著降低，而种类构成简单的群落则变化不大。2在6种植物群落中共出现27科68属87种高等维管植物，大多数物种具有狭窄的分布范围和较小的局域多度，而少数种具有较广的分布范围和较大的局域多度，并且这种分布趋势在不同的群落类型中又有所不同，γ多样性高的群落中特有种的数量增加；而γ多样性低的群落中稀有种数量相对较少。

Before the treatment of drought stress, most of communities can be classified into following seven types with biomass of dominant species which took account of 60% in the plots: Triumfetta bartramia, Urena lobata, Cynodon dactylon, Gahnia tristis, Ageratum houstonianum, A/rtemisia argyi and Ambrosia artemisiifolia. There was no dominant species in other communities. Totally, there are 33 common species distributed in these plots.

在群落自然生长一年后，根据群落内物种生物量所占比例，将样地群落划分为七个优势物种类型(优势物种生物量所占比例均在60%以上，盖度在群落内均最大)：刺蒴麻、肖梵天花、狗牙根、黑莎草、藿香蓟、家艾和豚草，其余为均匀度较高没有优势物种的样地。

Then, a dynamic strategy of finding education resources in grid communities based on small world is proposed, relevant algorism is compiled, and the finding of education resources fast and accurately in dynamic communities is realized.

The function and the changeable trait of cooperative economic organization among rural communities, and points out that our country's cooperative economic organization among rural communities is the realized shape of community ownership in rural district, not the artel on the real meaning.

论文第三部分重点研究了我国传统农村经济组织资源——农村社区合作经济组织的功效及可改造性，指出我国的农村社区合作经济组织并非真正意义上的合作社，而是集体所有制在农村的实现形式。

The benthic assemblage eco-positions of brachiopod communities in the early Early Carboniferous were between BA1 and BA2, and there were no BA3-BA5 deep-water communities in this area, which indicated that the sea water depth in this period was commonly less than 10 m.

本区早石炭世早期腕足动物群落的生态位介于BA1和BA2之间，缺乏BA3至BA5较深水群落（BA-Benthic Assemblage，底栖组合），说明该区早石炭世早期海水深度一般不超过10 m。

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。

To reveal patterns of longitudinal distribution, seasonal variation, and ecological succession in cladocerans communities in the Three Gorges Reservoir, ten sites were used to sample cladoceran communities across a longitudinal gradient from April, 2004 to January, 2005. Nine cladoceran species were collected throughout the year.
