查询词典 communities

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.

Based on a systematic field investigation and laboratory experiments, the structures of arthropod communities and the evalution of dominant predatory enemies in cabbage fields of different seasons were studied. The main results were as follows:1 The structures and their dynamics of arthropod communities in cabbage fields1.1 Species composition and population dynamics of each species of the arthropodcommunities in the cabbage fieldsThe research results showed that the occurrence of Pieris rapae in spring cabbage fields was relatively grave.

本文在田间系统调查和室内试验的基础上，对不同季节甘蓝田节肢动物群落结构及捕食性天敌优势种的评价进行了研究，主要结果如下：1甘蓝田节肢动物群落结构及其动态1.1节肢动物群落物种构成和各种群数量动态研究结果表明，春甘蓝田菜青虫的发生比较严重，菜青虫在调查期间种群数量呈上升趋势，5月初高峰期平均每株甘蓝接近20头；菜蚜与小菜蛾的发生相对较轻，菜蚜在5月中旬有个明显高峰。

By means of molecular biology, researchers identified some bacteria communities which had not been qualitative by microbe taxology nor been reported through conventional identifying methods. The effects of these bacteria communities on quyao are still waiting for further research.

The results show that the construction of the railway has an obvious effect on the warm steppe,but the characteristics of community,such as the coverage,ecological dominance and species richness of communities have been improved after its natural restoration,and some species,such as Elymus nutans,Aconitum gymnandrum and Thermopsis lanceolata,play an important role in the restoration communities.An assistant measure taken by human beings will benefit to the restoration.There is no any evidence of exotic invading plants in the restoration of the warm steppe in the study area.

结果显示，青藏铁路修筑过程对铁路两侧一定区域的温性草原有较大影响，但随着受影响区域植被的自然恢复，群落盖度、生态优势度和物种多样性等反应群落特征的指标都有一定程度的改善，一些在原生植被中很少出现或伴生种在恢复后的群落中有可能成为群落的优势种或建群种，如露蕊乌头和鹅绒委陵菜等；人为辅助措施将有利于受损植被的恢复；修筑铁路过程中受到影响的温性草原其恢复过程中尚未出现外来入侵植物。

He promised that next month will see the launch of an "ambitious household emissions reduction programme", and while Communities Secretary Hazel Blears welcomes the Budget because it will "help us support peoples aspiration to own their own homes and ensure communities are built in a way that will protect the environment for future generations", she is mindful that we also need to look at what we should be doing to tackle carbon emissions from the rest of our buildings - our offices, shops and pubs.
