应用室内培养试验的方法，研究武夷山市4种茶园土壤（红壤、潮砂土、高山草甸土、紫色土）的温室气体排放潜势及其对氮素的响应。结果表明：整个培养期间4种茶园土壤温室气体排放量差异显著（P＜0.05），其中高山草甸土茶园土壤温室气体排放量最大；氮肥均在一定程度上提高了茶园土壤温室气体排放量， CO2的排放量增幅为14.04％～29.58％，C H4的排放量增幅为2.34％～38.58％，N2 O的排放量增幅为21.27％～85.23％， N2 O受氮肥影响的敏感程度要大于CO2，加氮能显著增加高山草甸土和潮砂土温室气体的排放；CO2是茶园土壤主要的温室气体，对温室效应的整体贡献在94％以上， N2 O产生的温室效应为1.44％～5.89％，茶园土壤C H4产生量很低。茶园土壤温室排放量与土壤有机碳、全氮、硝态氮、铵态氮、容重、孔隙度均存在显著或极显著的相关关系，但与土壤全磷、碳氮比、pH值无显著性的相关关系。

A laboratory incubation test was conducted to study the emission potential of greenhouse gases from tea garden soils and its responses to the soil nitrogen fertilizer .Four soil types (red earth ,moisture sandy soil ,alpine meadow soil and purple soil ) were collected from tea gardens in Wuyishan City . The results showed that the greenhouse gas emission potential was significantly different between soil types (P< 0.05) ,the emission from alpine meadow soil was the largest .Nitrogen fertilizer increased the emission of greenhouse gases differently in cumulative amount of CO2 ,CH4 and N2 O for 21.27% -85.23% ,2.34% -38.58% and 21.27% -85.23% , respectively .The emission of N2 O responded more sensitively to nitrogen fertilizer than it of CO 2 .The application of nitrogen fertilizer significantly increased the emission of greenhouse gases from the alpine meadow soil and moisture sandy soil .The amount of CO2 dominated in the greenhouse gases of Tea garden soil ,which contributed for 94% of greenhouse emission from Tea garden approximately ,and it of N2 O contributed approximately from 1.44% to 5.89% ,but the CH4 emission was low in Tea garden soil .The greenhouse gas emission from Tea garden was significantly correlative to the content of soil organic carbon ,total N ,soil NO -3-N ,soil NH+4 -N ,soil bulk density and soil porosity ,but not to total P ,C/N and pH value .
