湿地的

Wetlands are important elements of a watershed because they serve as the link between land and water resources.

湿地是一个分水岭的重要因素，因为他们的土地和水资源的纽带。

And most of the endogenous rivers, the seasonal river ducks River was also evident, Jiaying winter blight and October each year down to the following year in May, the low-water ducks, some sections of riverbed revealed, forming numerous shoals, shallow water, deep water, the duck turned into a big river wetlands in river system, but also a large number of wild ducks therefore category Charadriiformes placing of wintering waterfowl and birds of prey, and the movement of supplies to.

和大多数上源性河流一样，鸭子河河水的季节性也很明显，夏盈冬枯，每年十月以降，至次年五月，鸭子河水位低落，部分河段河床显露，形成无数滩涂、浅水、深水区域，整个鸭子河变成一大的河流湿地系统，也因此成为大量雁鸭类鸻鹬类水鸟及猛禽的越冬地及迁徙补给地。

The constructed wetland was a good new ecological method for treating eutropic lakes water with abundant algae.

藻类的去除主要发生在湿地水流方向的前几层，而系统其他层对藻类只有微弱的去除效果。

Halophytic plants are the main vegetations on the north bank. Typha latifolia occurred on the south bank of Yellow River due to the eco-restoration engineering, indicating the law of vegetation succession in Yellow River Delta.

黄河北岸的植被主要以盐生植被为主，由于在黄河南岸实施恢复工程，南岸的植被中则出现了香蒲等物种，代表了黄河三角洲湿地植被演替的一个方向。

A local plant Suaeda heteroptera, which widely distributed in tideland ecosystem of Shuangtaizi Estuary, Panjing city, was selected in the Liaoning province as a object to study,.

以辽宁盘锦双台子河口潮滩湿地生态系统一种常见土著植物翅碱蓬作为研究对象，分析了Cu、Zn、Pb和Cd在该植物体内的累积分布、迁移规律并对其重金属的耐性进行了初步的探讨。

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.

结果表明，随着湿地水分由多到少的变化，植物群落类型发生相应的生态演替，其演替序列为水生植被→沼生植被→沼泽化草甸植被→草甸植被，且在水平方向呈对列式和同心圆式分布；从湖心至丘顶的垂直分布规律表现为水生植被→沼泽植被→沼泽化草甸→亚高山草甸→亚高山灌丛。

On the basis of enhancing mineralization of organic matter,and inducing non-biologi-cal stress on microorganic population as a result of soil freezing-thawing,it is summarizedthat global freezing-thawing soils are ...

本文根据土壤冻融加强有机质矿化作用，以及对微生物群体产生非生物应力的性质，结合冻融地区土壤和冻土带湿地所具有的特征，进行综合分析，论述冻融地区土壤是重要的N＿2O释放源。

Naturalists are concerned that diminishing wetlands are leading the water birds to overpopulate this refuge.

自然主义者博物学家担心，逐渐减少湿地是第一位的对水禽的影响，形成人口过密的避难所。

The Pn of Phragmites communis is higher than that of Phalaris arundinacea L, meanwhile Phragmites communis has the higher diurnal photosynthetic capacity, which shows that the Phragmites communis could grow more rapidly, and have higher biomass, so the Phragmites communis could be one of the priority implemental plant.

芦苇的Pn比虉草的Pn高，同时芦苇较虉草有更大的日光合量，说明芦苇相比较长势更快，生物量更高，当年栽植当年见效，在湿地生态系统人工修复中可作为优选工具植物之一。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

为了开发对植物病原真菌生长有抑制作用的药源微生物，本实验采用平板稀释法从江苏大丰盐沼湿地土壤中分离微生物，并通过菌丝块法检测这些微生物代谢产物对5种植物病原真菌生长的抑制活性，进而利用柱层析分析其活性成分；结果共分离得到235株细菌，其中好氧细菌92株，厌氧细菌143株；体外活性测试结果显示有65株至少对1种测试植物病原真菌的抑制率在30%以上，其中好氧菌39株，厌氧菌26株。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
