stage of succession

Development model of plant diversity in whole stage in forest community succession was simulated and improved . Simultaneously described the process of forest plant diversity within the whole stage of succession the causes were explained .

模拟并改建了森林群落不同的演替阶段植物多样性变化机理性模型，从而说明了森林植物多样性随演替阶段变化过程及其原因；

The community was in primary stage of succession , or was disturbed severely by outside .

群落尚处在演替初期阶段，或群落受到外界严重干扰。

C. carlesii forest of natural regeneration was in the middle stage of succession , and C.

天然更新米槠林处于演替的中级阶段，未达到顶级群落；

The results showed that natural plant communities have relatively high index of abundance , species diversity and evenness especially in third stage of succession ;

结果表明：处于植被自然恢复阶段的群落其物种丰富度指数、多样性指数、均匀度指数均在演替的第三阶段较高；

In the earlier stage of succession , the diversity usually was relatively large owing to the invasion of many species and the lack of dominance .

在演替早期，由于无明显优势种，物种的优势度较低，物种多样性指数较高。

The process of succession is stochastic because the invasion of the initial species is stochastic , but the final stage of succession is the same .

通过研究认为：同期发生演替其侵入样地的初期种是随机的，演替的历程也具随机性，但演替的终极阶段却是一致的。

The result showed that the litter could improve every stage of succession . On the Legal Succession The processes of forest succession could be expressed by the dynamic characteristics of dominant populations in forest .

森林群落的演替过程，是以各优势种群的动态为其表现特征的。

This indicates that the forest communities of Conghua Hut Spring Nature Reserve are in a transitional unstable stage of succession , which calls for strengthened conservation of the natural habitats and the forest landscape .

显示出该保护区的森林群落处于演替中的不稳定阶段，亟待加强对天然生境和森林景观的保护。

The relationship between community productivity and water resource were dependent on the stage of restoring succession .

群落生产力与水资源量的关系因恢复演替阶段不同而异。

Political struggle and always run through each stage of the succession of the throne , and each stage has a similar form of political struggle , but at different times of political struggle or show different characteristics .

政治斗争始终贯穿于每个阶段皇位的继承之中，每个阶段也都有类似的政治斗争形式出现，然而，在不同的时期政治斗争还是会表现出不同的特点。

Artemisia frigida populations are present in every stage of degraded succession of Chinese Inner Mongolia steppe . They have important effects on community structure and function , but spatial pattern of Artemisia frigida populations are poorly understood .

冷蒿（Artemisiafrigida）种群伴随着典型草原退化演替的各个阶段，对其所在群落的结构和功能具有重要的影响。

黄土丘陵区植被次生演替灌木初期的土壤养分特征

It is shown that the stratigraphic division and correlation are effective and have high precision according to the characteristics of each stage of the community succession .

它们都是群落演替和取代的特殊阶段，所以，根据群落演替的各个阶段能比较精确地划分和对比地层。

The species diversity indices of the scrubs did not decreased from initial stage to middle stage and to climax stage of succession .

灌丛群落的物种多样性指数值随着演替的进行，没有表现出降低的趋势。
