湿地的

Furthermore, the gist and method of calculating ecological pondage and ecological water requirement have been provided, and Zhalong wetland has been given.

本文提出了沼泽湿地生态储水量的概念与内涵，界定了其与生态需水量的区别与联系，探讨了两者的计算依据与方法，并以扎龙湿地为实例进行了计算。

Ecological water use of marsh can be ascertained according to ecological pondage and ecological water requirement, and the suitable quantity can be calculated basing on the marsh's water condition and the total water quantity, insuring that the pondage changes reasonably in spatial and temporal scale, so that the rational water allocation can be achieved.

实际用水配置中应以湿地系统的自然条件为基础，考虑生态功能需要，根据实际水资源丰枯情况，确定合理的补水规模，保证湿地储水量在时空尺度上合理变化，实现水资源的合理配置。

However,there is no consistent paradigm that indicates which primary producer is the energy base of salt marsh food web,and the extent to which salt marsh supports the estuarine fishery production.

然而，对于哪类初级生产是盐沼湿地食物网的能量基础、以及盐沼湿地对河口及滨海渔业生产的支持程度，仍然没有一致的结论。

人工孵化的美洲鳄鱼破开它们的壳而得自由在大柏树湿地在佛罗里达的湿地。

In order to promote the development of economy, people develop and utilize wetland largely and unreasonably.

中国湿地面积的减少、功能和效益的下降昭示着中国保护湿地资源的行动迫在眉睫。

The 134 genera of vascular plants had 14 areal-types, including 42 cosmopolitans 55 temperate types 30 tropic types 2 Mediterranean-types, 2 East Asia types and 1 endemic species. The cosmopolitan and temperate type accounted for 31.34% and 41.04% of all the genera, respectively revealing the azonal feature of the wetland vegetations and the influences of cold and wet climate on the formation and distribution of the vegetations.

维管束植物属有14个地理分布区类型，包括世界分布属42属、温带分布属55属、热带分布属30属、古地中海属2属、东亚分布属4属、中国特有分布属1属，其中世界分布属和温带分布属分别占区系维管束植物总属数的比例较高，分别为31.34%和41.04%反映了湿地植被的隐域性和冷湿气候对湿地植被发育、分布的影响。

Using the static chamber and Chromatograph method, H2S and COS emission from the marsh meadow Calamagrostis angustifolia and typical meadow Calamagrostis angustifolia were measured during growth season (5-9 month). the results showed that the seasonal and diurnal variations of H2S and COS emission were both obvious, the mean emission of H2S and COS from the marsh meadow Calamagrostis angustifolia were 0.34μg?

利用静态箱／气相色谱法，观测了小叶章沼泽化草甸和小叶章典型草甸两种湿地类型中H2S和COS在生长季（5-9月）的释放动态，结果表明：在两种小叶章湿地中，H2S和COS的排放通量均具有明显的季节和日变化规律。

The principle component 1 in Carex lasiocarpa could explain the species relative density of 88% and the aboveground biomass of 84%.

毛果苔草湿地中主成分1能够解释88％的物种相对密度和84％的地上生物量；小叶章湿地中主成分1对相对密度和地上生物量的解释量则分别为75％和58％。

The change speed of the fluviatile and lacustrine wetlands is the highest, and the annual dynamic change rate is as high as 2.60%, such reduction is mainly caused by that many small plots are degraded into saline or alkaline lands and marsh wetlands.

河流湖泊湿地在研究时期内则表现出最快的变化速度，年均动态度达到2.60％，它的这种减少变化是由数量众多的小斑块退化为盐碱地和沼泽湿地导致。

As in Hanshiqiao nature reserve, the community coverage of invasive plants like Humulus scandens can even reach 90% or more, they may have formed a community with only one dominant plant, which makes it impossible for the native wetland plants like Phragmites communis to grow.

如汉石桥湿地保护区，捧草等入侵植物的群落盖度达到90％以上，有些形成单优势的群落，抑制了芦苇等湿地植物的生长。
