| 摘 要： | 生物质炭和土壤强还原处理（Reductive Soil Disinfestation， RSD）可以有效地修复退化设施蔬菜地土壤，但2种修复技术联用对土壤温室气体（CO2、N2O和CH4）排放的影响研究报道较少.本研究采用室内培养实验，设置未修复土壤（CK）、生物质炭修复（BC）、RSD修复（RSD）和BC与RSD联合修复（BC+RSD）4个处理，35℃条件下培养15 d，研究BC与RSD单独以及联合修复对退化设施蔬菜地土壤温室气体排放和综合温室效应（Global Warming Potential， GWP）的影响.结果表明，与对照CK相比，BC处理土壤N2O排放量显著下降了50.0%，但CO2排放量和GWP均显著增加（p<0.05）；RSD和BC+RSD处理土壤CO2、N2O、CH4排放量和GWP均大幅度增加.但与RSD处理相比，BC+RSD处理土壤N2O排放量和GWP分别下降了71.0%和30.0%.相关分析表明，土壤CO2、N2O、CH4排放量和GWP与可溶性有机碳（DOC）和铵态氮（NH4+-N）显著正相关，与pH和硝态氮（NO3--N）显著负相关.可见，生物质炭可以减少退化设施蔬菜地RSD修复引起的GWP.
