演替

In construction of the city park, we should chose the suitable agrestic plants based on the basic theory of ecology and community succession and use the technique of"imitate nature" to construct the approaching nature communities in which the trees species were dominated and the shrub and grass were also included.

本文指出在城市公园建设中应以自然植被和群落演替的基本理论为依据，选择乡土树种即当地自然植被中的主要乔、灌木种类，&模拟自然&的技术和方法通过人工营造与植被自然生长的完美结合，建造以乔木为主体，乔灌花草多种植物相结合、常绿落叶相结合的近自然群落。

Agrioph yllum squrrosum and Psammochloa villosa community change Salix Cheilophila Schntid artifactitious vegetation community. No species was disappeared in succession. Between the species diversity and the time sandy barrier was positive correlation.

研究结果表明：随着沙障设置年限的增加，群落的物种数增加；群落类型由沙障设置前的沙米＋沙竹群落发展成沙柳人工植被群落，在演替过程中无物种消失，物种多样性与沙障设置年限基本呈正相关关系。

Miscamthus floridulus, Arundo donaxl, Artemisia argyi, Comnyza Canadensis, Crotalaris mucronata, and Kummerowia striata, are pioneer plants for vegetation recovery in coal piles. They have high summed dominance ratio and take crucial action on vegetation recovery and community succession. Many pioneer plants including annual and perennial herbs, e.g. Imperata cylindrical, Comnyza Canadensis, and Crotalaris mucronata colonize successfully to provide conditions for colonization of shrubs, e.g. Buddleja asiatica.

耐贫瘠、广布性植物如五节芒、荻芦竹、艾蒿、小飞蓬及豆科杂草猪屎豆、鸡眼草等是煤矸石堆植被恢复重建的先锋植物，它们在群落中综合优势比较大，对植被重建和群落演替起决定性作用；许多一年或多年生草本植物，如白茅、小飞蓬、猪屎豆等先锋植物的成功定居，为驳骨丹等灌木的入侵创造了条件。

Study of microbial ecology on the autecological factors, morphology and distribution of population and community succession was further carried out with the aim to understand the microbial characteristics in BAF.

为了探讨曝气生物滤池的微生物学机理，分别从个体生态条件、种群组成和分布、群落演替规律等方面研究了曝气生物滤池的微生物生态学特征。

In both types of autogenic succession pioneer species colonize quickly making opportunistic use of resources before the invasion of more competitive species.

在这两种自然发生的演替中先锋物种的移殖很快，在较强竞争力的物种入侵之前充分利用空间。

Oasis is one kind of azonal landscape developed under dry climate condition and surrounded by desert at small or medium scale, in which mesophytes or xero_mesophytes plants with relatively high primary productivity supported by runoff grows.

其具有径流依赖性、景观隐域性、演替双向性、分布边缘性、发展阶段性、空间分散性、易变性与基质的高反差性等特点；而人〓绿洲尚有儿何形状规则、生物多样性低、经济封闭等特点。

There are large niche overlaps between the shrub and semi-shrub species and among the herbaceous plants of which the overlap between H. scoparium and A. ordosica and between Chloris virgata and Bassia dasyphylla were 0.7192 and 0.8622, respectively, and this indicates that they have greater ecological similarity thus possessing strong competitive capacities in community succession; there are smaller niche overlaps between A. ordosica and various herbaceous plants and thus they can stably co-existed.

灌木、半灌木种之间、草本植物与草本植物之间的生态位重迭值较大，其中花棒与油蒿、虎尾草与雾冰藜之间的生态位重迭值分别为0.7192和0.8622，这表明二者之间有较大的生态相似性，从而在演替过程中具有较强的竞争作用；而半灌木油蒿与各草本植物之间的生态位重迭值很小，它们能够实现稳定共存。

Meantime, spatial and temporal variation of benthic algae community was investigated in Lake Donghu.

同时对东湖底栖藻类群落全年的分布格局、季节演替以及与主要环境因子间的相互关系进行了研究。

Moreover, the development of the fouling community on an offshore installation also represents a simplified model of the benthic community recovery.

此外，探讨污损生物群落的演替变化机制还可为海洋恢复生态学的发展提供借鉴。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
