湿地

The research carried out an experiment of extracting water from inland limnetic wetlands using TM remote sensing imagery based on many arithmetic,and concluded that spectrum classification was the best among the area accuracy index,extraction accuracy index and visual effect index,the following was single band threshold and vegetation index method,however,multi-band relationship and water index method was the worst.

研究基于TM遥感影像，运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验，通过对实验结果的分析得出：在面积的准确性、提取的准确度以及视觉效果3种指标下，光谱分类法较其它方法效果要好，其次为单波段阈值分析法与植被指数法，较差的是多波段谱间关系法与水体指数法；影响提取效果的主要原因是湿地水体提取不够完全，这是由影像的分辨率及湿地特殊的水文条件所造成的，采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。

In the study area, the thinning-out line of albic horizon is coincident with the 55.74m contour line, and the maximum horizon error was less than 1m and the maximum vertical error less than 0.04m.

基于湿地边界标准的湿地的定义应为：湿地是陆地和水体之间的过渡带，是由于地表淹水／土壤水饱和而形成的一种隐域性自然综合体，其上界位于陆地土壤诊断层的尖灭点处，其下界是有根植物下界。

The number of the species of macrofauna of the Lotus flower bridge mudflat in the spring, summer, autumn and winter were respectively 19, 20, 20 and 12, respectively.

结果在两地共发现大型底栖动物38种，分别隶属于4门5纲24科，其中澳门莲花大桥滩涂的大型底栖动物有4门5纲23科34种，占两个湿地总种数的89%；路凼湿地大型底栖动物有3门4纲15科21种，占两个湿地物种数的55%。

Constructed wetlands include canal, pond, fishing pond and paddyfield. Types of wetlands in Sanchahe area are typical and representative. The wetlands area is suitable. Water quality is perfect.

湿地的类型具有典型性和代表性，湿地的面积适中，水质良好，但水资源季节分配不均，人为干扰严重等问题是湿地保护的制约因素。3。

PEATY wetlands emit about 1.3 billion tonnes of CO2 a year as a result of human activity that drains them and thus exposes them to the oxidative effect of the atmosphere.

作为人类活动的结果，含泥炭的湿地每年排放大约13亿吨二氧化碳。人类排干含泥炭湿地的水，从而使湿地暴露在空气中氧化。

BOGS, mires, marshes, swamps, fens and quagmires—whatever they are called, and wherever they are found, peaty wetlands emit about 1.3 billion tonnes of CO2 a year as a result of human activity that drains them and thus exposes them to the oxidative effect of the atmosphere.

湿地也好，沼泽也罢，不管它们叫什么，不管它们在哪里，每年因为人类的湿地排水活动，泥炭湿地会排放13亿公吨的二氧化碳，人类的活动使得这些沼泽在大气层的氧化效应下暴露无余。

In this paper, the applied researches of PEEN (Physico-Ecological Engineering) theory demonstrated the significant effect in renovating LW resource and environment, in the project of"Hongfeng Lake in GuiYang"and in the project of"Mochou Lake in NanJing"Moreover the author discussed the special and rescue protection countermeasure by constructing LW nature reserves in the areas of important value in its resource and environment.

以物理生态工程在"贵阳红枫湖"、"南京莫愁湖"工程中的应用为例，本文实证了PEEN在湖泊湿地资源环境局地恢复中的明显效果；以洪泽湖湿地自然保护区建设规划的实践研究为例，探讨了重要湖泊湿地的抢救性保护对策，为解决上述矛盾提供了决策依据和可操作的途径。

Based on the relict gull distribution at Hongjiannao lake and its protection significance, varies of manage policies, including the "protect island and bank" policy and establishment of watch station, and so on, were introduced in details, which is significant for the protection of wetlands.

在研究红碱淖湿地遗鸥种群的资源分布及保护意义的基础上，详细介绍了"保岛护岸"、建立保护观察站等保护红碱浮湿地及其遗鸥种群所采取的多样综合管理措施，为湿地保护及发展提供借鉴。

It is the first systematical survey on the characteristics and changing trend of the wetland in Macau, where has been believed to be the most important place for the world threatened bird species, black-faced spoonbill Platalea minor living through the winters; 2. some effective suggestions and strategies also have been proposed to protect the wetland ecosystem in Macau based on these characteristics.

该研究的创新之处在于，(1)首次系统全面地研究了世界珍稀濒危鸟类黑脸琵鹭的重要越冬栖息地澳门海岸湿地生态系统的特征及变化趋势：(2)在掌握澳门湿地生态系统变化特征的基础上提出了保护澳门湿地生态系统的建议和对策。

While, in suburb Wetland Park planning, the top-drawer ecosystem services are water quality and water supply reservoirs, and biodiversity conservation.

不同区域的湿地公园其恢复和重建的核心生态服务功能应在科学分析研究的基础上因地制宜地确定，例如：城市建成区域中建设的湿地公园应以水质净化和调节改善小气候为恢复和重建的核心生态服务功能；城郊的湿地公园应以水质水源保护和生物多样性保育为恢复和重建的核心生态服务功能等等。
