演替

Tolerance: late successional species invade because they are able to tolerate lower resource levels and can outcompete early successional species.

iii耐受：后期演替的物种的入侵，因为它仍能够忍受较低的资源水平和排斥早期演替的物种。

Anaerobic synecology of the hydrogen-producing fermentation system was investigated under certain test condition in this thesis. In the continuous flow system of anaerobic hydrogen-producing fermentation, the succession of hydrogen-producing acidogenic microbiology may be regressive process. By regressive process we means that the original community getting from nature which structure being complex with a high ability would degenerate gently to a certain climax community which structure being simple with less ability.

产氢发酵系统的微生物群落生态学研究证明，在连续流发酵产氢反应系统中产氢产酸发酵细菌群落的演替过程，是在人为控制的生境条件下，微生物从自然群落这种稳定性大、组成及生化反应过程复杂的生态群落，向稳定性小、组成和生化反应过程相对简单的某一产酸发酵顶极群落进行的"逆行演替"。

The result showed that species diversity of plant community in sands of the different succession phases was increasing trend. The plants of Leguminosae and Chenopodiaceae, as dominant plant species in the shifting sand, demonstrated a strong ability for adaption.

结果表明：不同演替阶段沙地内植物群落多样性呈不断增加的变化趋势，各演替阶段均有不同的植物群落和优势物种。

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。

Degradative succession is a type of augogenic succession involving colonization and subsequent decomposition of dead organic matter.

退行性演替是涉及到移殖和死亡有机体后来腐烂分解的自发演替的一种类型。

New collapses are ceaselessly induced by the special geology geomorphological process, and then a new primary succession starts from bare rocks.

特殊的地质地貌过程使之不断有新的崩塌，从裸露的岩石开始的新的原生演替，如此形成不同时间系列的原生演替阶段。

With distance from the lake,the Aerxiaote lake vegetation happened converse succession.From outside to inside,the structure of plant community was gradually simple,biological diversity was shrinking and halophytic vegetation had decreasing tendencies.From outside to inside,there were Aneurolepidium dasystachys,Phragmites australis,Suaeda salsa L.community.Succession tendency was from wetland and typical grassland vegetation to salinization and desertization vegetation.

阿尔肖特湖边的植被随着距湖面距离及地形的不同，植被发生逆向次生演替，自外向内具有植物群落结构逐渐简单，生物多样性逐渐降低、盐生植物逐渐增加有规律性变化趋势；植被由外至内依次形成了赖草、芦苇、白刺和盐地碱蓬群落梯度，其演替趋势是由湿地和典型草原植被向盐碱化和荒漠化植被过渡。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

The results indicated that there was an ecological succession of wetland plant communities and that the successive series is as follows: aquatic plant→helophytes→swampy prata→herbosa with the changes of habitat from aquatic to mesophytic. The horizonal distribution regularity of plant communities showed symmetric distribution at loop lake or banks of small stream and con centric distribution at depression. The vertical distribution regularity is as follows: aquatic vegetation→moor vegetation→swampy prata vegetation→subalpine meadow subalpine shrub from the center of lake to the hilltop.

结果表明，随着湿地水分由多到少的变化，植物群落类型发生相应的生态演替，其演替序列为水生植被→沼生植被→沼泽化草甸植被→草甸植被，且在水平方向呈对列式和同心圆式分布；从湖心至丘顶的垂直分布规律表现为水生植被→沼泽植被→沼泽化草甸→亚高山草甸→亚高山灌丛。

Under natural conditions and with human activity, the dominance of Oxytropis coerulea become weaker than ever among associations, which reflects a tendency of inverse succession, while those which are less disturbed by human activity show xerosere character because of poor habitat.

在自然条件和人为干扰双重作用下，蓝花棘豆Oxytropis coerulea在群丛中的优势度明显弱化，群丛反映出逆演替趋势，受人为干扰较少的群丛则由于生境条件较差显现旱生演替特征。

It goes back to what I told you...

现在回到我告诉过你的。。。

With a supporter in Mr Charest and an admirer in Mr Dumont, Mr Harper may be encouraged to call an election himself.

由于在沙雷那边有个支持者，杜蒙那边有个崇拜者，鼓励哈珀为自己举行一次选举。
