群落

The decreasing trend type,which is the main type in China,including the north part ofDaxinanling,the Xiaoxinanling,the Changbai Mountain,the Maxian Mountain,the westpart of Tianmu Mountains,the Mupu Mountain,the Donggong Mountain,the BaizuMountain,the Jiufeng Mountains,the Jiulong Mountain,the Fengyang Mountain,theWangyang Mountain,the Badagong Mountain,the Hefeng Mountain,the Qixing Mountain,the Fanjing Mountain,the Leigong Mountain,the Xishan in Kunming,the Jinfo Mountain,the Haba snow Mountain,the Zhenkang snow Mountain in which the plant species diversitydecreased steadily,and the Huangshan Mountain,the Hualong Mountain,the SheulongjiaMountain,the Dupangling,the Jiu Lian Mountain in which the species diversity decreasewith the difference,the latter is of a slight"the mid-altitude bulge".

趋势减少型为我国山地森林群落植物物种多样性变化的主要形式，其中再区分为大兴安岭北部山地、小兴安岭、长白山、马衔山、西天目山、幕埠山、洞宫山、百祖山、南鹫峰山、九龙山、凤阳山、万洋山、八大公山、鹤峰山、七星山、梵净山、雷公山、昆明西山、金佛山、哈巴雪山、镇康大雪山等平稳减少型；黄山、化龙山、神农架、都庞岭、九连山和武夷山地、点苍山、西双版纳低山地等波动减少型，这些山地存在轻度的"中等高度的膨胀"现象，但东北地区的山地、浙闽粤低山丘陵区的大部分山地、湘西、鄂西和川黔交界区山地的"中等高度的膨胀"现象不甚明显

Social insect living in organized colonies; characteristically the males and fertile queen have wings during breeding season; wingless sterile females are the workers.

群居昆虫，生活在有组织的群落中；特征是雄性和有生殖能力的蚁王在繁殖季节有翅膀；没有翅膀、不能生育的雌性为工蚁。

Solidago canadensi invaded more severely, the species was lower, the vegetable diversity of the plant community was smaller.

加拿大一枝黄花入侵的程度越严重，群落中物种丰富度越低，植物多样性越小。

Finally,the paper analyzes the evolution process from the holistic perspective,and draws the conclusion that the communities evolve spirally.

最后从整体的角度进行分析，得出群落螺旋上升式演化的结论。

Climatic climax A plant community that is in equilibrium with a stable climate.

气候顶级群落：与稳定的气候平衡的植物群落，它代表演替的顶级。

The present investigations show that Bt rice possesses high efficiencies for controling rice stem borer, yellow stem borer and rice leaf roller, and there are no significant differences in growth and development of non-target organisms, such as rice planthoppers, leafhoppers and predators, and the stability of arthropod community structure between Bt rice and conventional rice paddy habitats.

现有的研究表明，Bt水稻对二化螟、三化螟和稻纵卷叶螟等主要靶标害虫具有较高的抗性水平，对稻飞虱、叶蝉、捕食性天敌等非靶标生物的生长发育和稻田节肢动物群落的稳定性无明显影响。

Mixed pasture has a lot of advantages in respect of quality, yield and communities stability, so that it is an essential part of intensivism stockbreeding.

混播草地牧草的质量优、产量高，群落稳定性好，是今后集约化畜牧业发展的重要内容。

The characteristics of clonal growth and resources sharing were important to keep stability of community. The transpiration and the stomatal conductance of stolon with and without adventitious roots were same. But the water potential of stolon without adventitious roots was higher than that with adventitious roots.

臭柏克隆生长和资源共享特性在维持群落稳定中起着重要作用，来源于同一上级枝的匍匐茎，有不定根的和无不定根的日平均蒸腾速率和气孔导度没有差异，但无不定根匍匐茎的叶水势比有不定根的高。

In this investigation, the number of maternal ramets and daughter ramets, length of stolon and spacer, distributed pattern of spacer and the relationship with community quantitative character were compared and researched between the two Potentilla. This offers basic data for more discussions to ecological and phenotypic adaptive strategy of the two population.

本文就两种委陵菜种群的母株、分株数量、匍匐茎长度以及间隔子长度及其布局及其与群落数量特征的关系进行比较研究，为进一步深入探讨这两种委陵菜种群的表型适应与生态适应策略提供基础性研究数据。

Streptomyces and Bacillus are always existed in different seasons which are likely to the aboriginal population in soil bacteria community.

链霉菌和芽孢杆菌在季节交替过程中一直存在，可能是构成土壤细菌群落的原始种群。
