湿地

A blue-feathered barn swallow, part of the thousands of migratory birds descend on Candaba marsh north of Manila. Thirty years ago the marshes covered some 32,000 hectares (79,000 acres) but with the spread of agriculture and urbanisation just 72 hectares remain

这是一只蓝羽家燕，它是马尼拉北部Candaba湿地上成千上万只迁徙鸟儿中的一员。30年前，这些湿地曾占地32，000 公顷（79，000英亩），而如今，由于农业发展加上城市扩张，只余下72公顷了。

Being an important part of global carbon cycle,the biogeochemical process of organic matters in wetlands has been focused on for the recent decades.

同时作为全球碳循环研究中的重要内容之一，有机质在湿地中的生物地球化学过程研究一直备受关注，然而迄今为止，关于河口湿地中有机地球化学的研究还有待进一步的充实和完善。

Wetland biogeochemistry is the core of wetland ecosystem ecology process.

湿地生物地球化学是湿地生态系统生态过程的核心研究内容。

With a sample study area in Xi'an Bahe River,the urban wetland biotope formation and evaluation issues were discussed in this paper.

本文结合西安市灞河湿地研究样区，对城市湿地鸟类生境构成与评价问题进行了探讨。

In the survey 7 populations including 74 individuals of wintering Black-faced Spoonbills were found.

本次黑脸琵鹭的越冬调查历时3个月，共7个省，基本上覆盖了江苏以南的东部沿海主要湿地和主要的岛屿沿岸湿地。

Also it can be concluded that the narrower the width of the channel is, the higher the flood level rises.

对于在河流中如何布置和种植人工湿地及湿地植物的选取具有一定的指导作用。

Also it can he concluded that the narrower the width of the channel is, the higher the flood level rises.

对于在河流中如何布置和种植人上湿地及湿地植物的选取具有一定的指导作用。

The results show that, the nitrate-N concentration in groundwater in the reed area was 0.2~0.8mg/L and significantly lower than that in surrounding wells (more than 20mg/L), and the reed wetland can remove nitrate pollution in shallow groundwater. The distribution of denitrifying bacteria showed obvious rhizosphere effect, and the higher biodenitrification in natural reed wetland was related to the distribution of denitrifying bacteria. There was a negative relationship between the nitrate-N concentration and the number of denitrifying bacteria in groundwater.

结果表明：芦苇区浅层地下水中硝酸盐氮仅为0.2~0.8mg/L，远低于湿地周围井水中硝酸盐氮质量浓度（大于20mg/L），芦苇湿地能够去除浅层地下水中硝酸盐污染；反硝化细菌在土壤中的分布呈现明显的根际效应；野生芦苇湿地较强的生物脱氮作用与反硝化细菌分布有关，地下水中硝酸盐氮含量与反硝化细菌分布呈负相关。

However,there are some ecological crisis emerged in Qilihai recent decades.Making reference of many experiences of wetland protection,recovering and development,this paper gives some rational suggestions of ecological restoration and green development in wetland:protecting and managing it according to law and rules of reserve firstly;recovering nature function of the river which had compensated for ecol...

近几十年出现了严重的生态危机，本文借鉴众多湿地保护与开发经验，就七里海湿地生态恢复与绿色开发利用提出了一些可行的措施：依据自然保护区的相关法律法规对其进行切实保护与管理，通过恢复河流生态补水、翻耕苇地、禁捕鸟类等生态修复措施恢复其生态功能，进而发展湿地绿色产业、开展项目建设环评等绿色开发活动发挥其重要的生态、经济和社会价值。
