本文研究结果如下：（1）3种植物沼泽湿地土壤的CH4产生率在培养前期达到最大值后，随培养时间逐渐降低。

The results showed : ( 1 ) The methane production rates reached the maximum on the third day in three kinds of plant marsh soil , then gradually decreased with incubation time .

自然沼泽湿地土壤中元素垂直分布分层性较明显，而农田土壤中，除Pb外，其他元素含量的剖面变化较自然沼泽湿地平缓，但剖面变化的趋势基本一致（B和Cd除外）；

The vertical stratification of trace elements in natural wetland soils is significant while in tillage soils section changes of elements , except Pb , are gentler than those in natural wetland soils . Some elements in wetland and tillage soils have a similar trend excluding B and Cd .

结果表明，沼泽湿地土壤有机碳的垂直分布随土壤深度、植物群落类型和农业耕作方式的变化而变化；

The results show that the vertical distribution of SOC in wetlands varies with soil depth , type of plant communities and tillage pattern .

而沼泽湿地土壤中硝态氮的运移通量与土壤水扩散率及土壤含水量都呈显著正相关关系，并随土壤水扩散率的增加呈指数增长。

But these fluxes had obvious positive correlation with diffusibility and content of water in soil and the exponent increased with the increase of soil water diffusibility .

结果表明，沼泽湿地土壤中硝态氮的运移通量与运移距离显著负相关，并随运移距离的增加呈一阶衰减指数变化；

The movement fluxes of nitrate nitrogen in the wetland soil had obvious negative correlation with the movement distances , and varied in one-order exponent decay with increase of the distances ;

湿地垦殖后，在相同季节根层土壤温度明显高于沼泽湿地土壤，但垦殖后土壤有机碳、氮素含量明显降低，C：N比值减小，土壤呼吸通量增大，且具有季节性变化。

The soil temperature of rhizosphere is distinctly higher after cultivation of mire soil , but soil organic carbon and nitrogen levels , and C : N ratios decreased notably after reclamation .

主要土壤有水稻土、冲积土和滨海盐渍沼泽土（海涂土壤）等三个土类。

The three major soil types in this region are the paddy soil , the alluvial soil , and the salt swamp soil .

降水减少导致的沼泽水位下降将加强若尔盖高原沼泽土壤氧化CH4从而减少沼泽CH4排放。

The falling of bog water level caused by raining decrease would strengthen the CH4 oxidation by bog soil in Zoige Plateau , thus the CH4emissions from bog decreased .

融化过程中，由于泥炭沼泽土渗透性较草甸沼泽土低，土壤化通后，其表层能滞留更多的水分。

In melting process , more water is blocked in upper layer because peat mire soil permeability is lower than meadow marsh soil .

沼泽水位的变化引起沼生植物种群更替，从而形成不同类型的沼泽及其土壤剖面形态特征，进而导致沼泽产生和排放甲烷能力的不同。

The depth of water table affects the pattern of vegetation in mires , which , in turn , strongly influences the development and soil profile of mires , resulting in discrepancy in flux of methane emission from various mires .
