生物群落

The riparian zone has four-dimensional structure characteristic with portrait, diastrophism, perpendicularity and changing by time which is outcome between land and hydrophily in space. It has important function in landscape pattern.

河岸带具有四维结构特征，即纵向、横向、垂直方向和时间变化(如河岸形态变化及河岸生物群落演替)4个方向的结构，是空间内陆地——水生态系统发生直接相互作用的产物，在景观格局中有重要的作用。

In chapter one, the former mono-disciplinary studies to the karst mountain in southwest China are analyzed and summarized.

具备复杂多变的小生境和以此为基础的多样性较高的生物群落。

During spring and fall turnovers , when organism from the upper layers enter this zone , is life abundant in profundal water.

这一层只有在春秋 turnover 的时候，才有丰富的生物群落在此活动。

Based on the three bottom trawl surveys in adjacent waters of Changjiang estuary in June, August and October 2006, the composition and variation of the functional groups of high trophic level communities in the waters were studied.

通过对2006年6、8和10月在长江口及邻近海域3次调查采集样品的分析，对该水域的高营养层次生物群落的功能群组成及其变化进行了研究。

Water is not only a carrier of lives in biotic community but also a medium for energy movement and matter cycling.

水是生物群落生命的载体，又是能量流动和物质循环的介质。

Then in 1875, out of nowhere, a well combination of wind currents, drought and basic biology, set the stage for the unthinkable -- the biggest baddish swarm ever recorded.

接着在1875年，不知从哪里出来的，一次风流，旱灾和基本的生物群落的正好的结合，促成了上演这个意想不到的——曾被纪录的最大的害虫群。

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。

A field experiment on the reproductive allocation of the annual plant Eragrostis poaeoides was carried out in the re-vegetated areas in Shapotou of the Tengger Desert.

繁殖是生命得以延续的唯一手段，它不仅是种群形成、发展和进化的核心问题之一，也是生物群落和生态系统演替的基础。

Scientists hae long assumed that the physical structure and condition of stream and rier channels hae perasie effects on biological communities and processes, but specific tests are few.

长期以来，科学家认为河道的结构、形态能影响生物群落和生命过程，但相关研究较少。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
