Results show that Calamagrostis angustfolia wetland is higher than cropland in content of total sulfur and available sulfur, which indicates cultivation depletes soil S, and soil total sulfur and available sulfur show a decreasing trend with each passing year.

结果表明，小叶章湿地土壤总硫和有效硫含量高于开垦后的农田土壤，开垦导致土壤硫含量下降，且随着耕种年限的增加，土壤总硫和有效硫含量呈逐年下降趋势。

From May to October 2004, the seasonal changes of K, Ca, and Mg contents and accumulation in Calamagrostis angustifolia, the dominant species in the typical meadow anti marsh meadow communities of Sanjiang Plain, were studied.

2004年5-10月，对三江平原典型小叶章草甸和小叶章－苔草沼泽化草甸群落优势植物小叶章的K、Ca、Mg含量与累积的季节变化进行了研究。

N2O emission fluxes before and after reclamation of Calamagrostis angustifolia wetland in Sanjiang Plain were observed in situ with static-chamber and GC methods.

利用静态箱-气相色谱法对三江平原小叶章湿地开垦前后N2O的排放通量进行了原位测定，分析了N2O通量特征及其与温度、水分等环境因子的关系。

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。

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.

以三江平原典型环形湿地为研究对象，在小叶章群落、沼柳小叶章群落、漂筏苔草群落、塔头毛苔草群落，采用黄盘诱集法和扫网法定期对湿地昆虫群落进行采集，研究了该区内的昆虫生物多样性及其季节性变化特征。
