湿地的

The main mechanism of nitrogen in wetland systems is the action of microorganisms,while the removal efficiency will increase with the protraction of HRTin wetland,and also the action has a close relationship with the alternant changes of DO formed by the undee flowing.

湿地系统除氮的主要机制在于微生物的作用，随停留时间的延长湿地系统对氮的去除效率增加，且该作用与波形水流状态所形成的溶解氧交替变化有关。

因此，开展澳门海岸湿地生态系统特征及变化趋势的研究，不仅有利于促进澳门海岸湿地生态环境的良性与可持续发展，而且，可以使澳门有效地履行保护世界珍稀濒危鸟类黑脸琵鹭的国际义务，提升澳门在世界环境保护科学事业中的国际地位和影响力。

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.

区系中的单细胞浮游藻类包括近岸广布种116种、近岸暖水种31种、近岸温带种26种；维管束植物被划分为6大生态类群，包括盐生植物24种、水生植物22种、湿生植物35种、中生植物103种、旱生植物6种、沙生植物4种，保护区内湿地植被的建群种、优势种均为水生植物、湿生植物或盐生植物，反映了湿地植被的隐域性；维管束植物按照生活型划分，有20种高位芽植物、4种地上芽植物、54种地面芽植物、48种地下芽植物和68种1年生植物，其中地面芽植物、地下芽植物占区系植物总种数的比例较高，占52.58%，反映冷湿气候和局部低洼积水环境对区系的形成起较重要作用。

There are about 100 species plants in the wetland, and the majority is herbage and frutex. These plants included Polygonum hydropiper, Nelumbo nucifera, Annua Linn, Phragmites communis etc. At the same time, there are also 48 species animals, which belong to 30 families, and these animals included Ciconia ciconia, Cygrus cygrus, Platalea leucorodia, Meles meles etc.

湿地内有高等植物近100种，其中草本和灌木占大多数，典型的如水蓼、莲藕、早熟禾、芦苇等；在此栖息的动物有5纲共18目30科48种，具有代表性的如黑鹳，大天鹅、白琵鹭、狗獾等，是铜川市重要的水源补给地和湿地保护区，对于当地生态环境和经济社会可持续发展意义重大。

In 1999, WWF began supporting the nomination and gazetting of Ramsar sites in China. By Feb. 2, 2002, China had added 14 new Ramsar sites, an achievement that WWF and SFA celebrated together as the 71st Gift To The Earth.

世界自然基金会从1999年开始支持中国的国际重要湿地申请与加入工作。2002年2月2日，中国新增的14个国际重要湿地，被世界自然基金会确认为第71份&献给地球的礼物&，当时我们与国家林业局也在北京举行了隆重的庆祝仪式。

By using the normalized difference vegetation index extracted from CBERS-02 data and the leaf area index data obtained from field measurement, this paper analyzed the relationships between the NDVI and the LAI of total samples of meadow, marsh vegetation, shrubs, and islanded forests of the wetland vegetation in Honghe Nature Reserve of Sanjiang Plain. The linear and non-linear regression models between NDVI and LAI of different wetland vegetation types were established, and the spatial distribution of LAI in the Honghe Nature Reserve was mapped.
