演替

This regional community structure is simple. The shrub layer and the liana layer are undeveloped. The syngenesis time is short.

调查表明该区域群落结构简单，灌木层和层间结构不发达，群落演替时间短。

It differs from predestination ante prvisa merita in two points: first, it rejects the absolute decree and assumes a hypothetical predestination to glory; secondly, it does not reverse the succession of grace and glory in the two orders of eternal intention and of execution in time, but makes glory depend on merit in eternity as well as in the order of time.

它不同于宿命前厅prvisa merita有两点：第一，它否定了绝对的政令，并假定一个假设性的宿命走向辉煌；其次，它并不逆向演替的恩典和荣耀，在这两项命令的永恒的意图和执行时间，但使荣耀依靠优异在永恒以及在该命令的时间。

This study was carried out in collective-owned summer grassland in Ganchaitan, which is located at the south foot of eastern Lenglongling Mountain (a branch of north Qilian Mountain), with yak and Tibetan sheep miscellaneously grazed on it. The grassland type could be classified as alpine meadow, dominated by Potentilla froticosa shrub. This study, under grads grazing stress, focused on the community structure, composition, species diversity, above-ground biomass of PFS, by using pane net sampling based on spatial distribution in stead of temporal succession. Results showed that: Grazing stress negatively related to the distance between grazing area and resident area.

以祁连山北支冷龙岭东段南麓的甘柴滩夏季牧场集体长期混合放牧的高寒金露梅Potentilla froticosa灌丛草场为对象，利用空间分布代替时间演替的方法，采用方格网法取样分析调查，对不同放牧压力梯度下金露梅灌丛群落的结构、组成、物种多样性、地上生物量进行研究，结果表明：①放牧居住点由远到近，放牧压力梯度不断增加，金露梅株高、密度、覆盖度、地上生物量和丛间草地的地上生物量均有不同程度的降低，地上的总生物量降低幅度达84.77%。

The reduction of species richness was the most remarkedble in Trichoptera and Mollusca. Species succession of macrozoobenthos was closely related to the changes in environmental conditions such as the isolation of the lake from the river, eutrophication, and disappearance of macrophytes. Perhaps, the latter two changes were more important.

分析表明东湖底栖动物群落的演替与湖泊环境条件的变化关系密切，这些变化主要包括：江河阻隔，湖泊富营养化的加剧以及水生高等植物的消失，其中后两个因素相对前一个显得更为重要。

Such as Pui Pui's home, Succession Walk, Mangrove and Mudflat Hide.

于是我们自行分组，按照作业上的指示参观及游览这个湿地公园，像佩佩之家、演替之路、红树林和观鸟区。

In our prior work, including three experiments in two different habitats, we showed that the presence of the mutualism can reduce plant diversity and slow plant succession from grassland to forest.

在我们以前的工作，其中包括3名在两个不同栖息地的实验，我们发现，该互惠的存在可减少植物多样性和草地缓慢植物演替森林。

Environmental changes in the Swan Oxbow of the Yangtze River in China in the last 3 decades have been documented by morphological diversity, ecological characteristics and assemblages of testate amoebae, combined with pigment data.

通过对天鹅洲长江故道近代沉积物中有壳变形虫的形态、生态特征和多样性组合变化的研究，重建了该地区30a以来有壳变形虫的群落演替过程。

In spite of its short history, it develops rapidly and is widely used in core correlation, material source identification, sediment tracing, ecosystem evolution, paleocliamtic and paleoenvironmental study, pedology, environmental pollution, oil and gas exploration and paleomagnetism.

尽管其历史不长，它的发展却异常迅速，在样芯对比、物质来源鉴别、泥沙运移示踪、流域生态环境演替、古气候和古环境研究、土壤发生学、环境污染、油气勘探、古地磁学等领域得到了广泛应用。

The environmental requirement for plants and the successional trend of vegetation can be further understood by means of researching the regularity and diversity of phyllotaxy, besides, some auxiliary resources would be added in respect of the plant taxonomy and ecological conservation.

由叶序的规则性与歧异性发展，可以进一步了解植物对於环境的需求和植群演替趋势，而在植物分类及生态保育上，增加一些辅助资源。

Phytogeography which study flora geography and vegetation geography research the relation between the plant distribution and space and time. It has great meaning for studying plant distribution , flora evolve , protection and utilization of plant resources, vegetation evolve etc..

植物地理学研究植物区系地理和植被地理即植物分布与空间及时间的关系，对于研究植物的分布、区系演化、植物资源保护和利用、植被演替等均有重大的意义。

It goes back to what I told you...

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。
