温室气体排放与土壤理化性质的关系研究进展

Advances on Research of Relationship between Soil Physio-chemical Properties and Greenhouse Gase Emission from Soils

根据国内外研究温室气体的文献资料 ,综合分析了土壤理化性质对3种主要温室气体(CO2,CH4,N2O)排放影响的研究进展情况。影响温室气体排放的土壤理化性质主要是土壤有机质、质地、温度、湿度或Eh、pH。因此 ,深入而全面的研究土壤CO2、CH4、N2O排放与土壤理化性质之间的数量关系 ,尤其是与土壤基础物质之间的关系 ,估计土壤CO2、CH4、N2O的排放总量 ,初步提出区域性的温室气体减排方案是将来的主要研究方向。

Greenhouse gase emission from soils is mainly controlled by soil physical and chemical properties.Key factors influencing the production and emission of CO 2 ,CH 4 ,N 2 O from soil are organic matter content,temperature,water content or Eh,pH and soil texture.It is recommended that future study be focused on quantitative description between CO 2 ,CH 4 ,N 2 O emission and these key factors,especially soil matrix,estimation of regional amount and feasible ways of reducing emission from soils.
