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。

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。

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。

To explore the effects of exogenous nitrogen input on the enzyme activity of Calamagrostis angustifolia during litter decomposition in a freshwater marsh, we supplied dissolved NH4NO3 (N0:0; N1:6 g·m-2·a-1;N2:12 g·m-2·a-1) to field plots on the Sanjiang Plain and determined the enzyme activities of litter decomposition within 160 d using litter bags.

以三江平原沼泽湿地典型湿地植物小叶章枯落物为研究对象，采用分解袋法研究了不同外源氮输入(N1、 N2分别为 6 、12g·m-2·a-1)对小叶章枯落物分解过程酶活性的影响，并设置对照区（N0，0 g· m-2·a-1）进行比较。

A survey was conducted to study the biodiversity and seasonal change of insects in four plant communities, Calamagrostis angustfolia, Salix brachypoda-Calamagrostis angustifolia, Carex pseudocuraica, Carex casiocaepa, in a typical annular wetland in Sanjiang Plain by the methods of yellow-pan trap and net-sweeping.
