Reuse of the waste in agriculture is a hot study recently, however, the environmental impact assessment for the reuse was rarely reported. Taken Fuzhou jasmine plantation as the case study, the carbon emissions and comprehensive global warming potential were determined after the reuse of sole straw and straw amended with gypsum slag, biochar, steel slag on jasmine plantation. The results show that:①the CH_4 emission fluxes increased by 20.05% after straw amendment with gypsum slag, biochar, however, decreased when amended with steel slag.②CO_2 emission fluxes increased by 30.45% after straw amendment. with gypsum slag,while decreased after straw amended with biochar and steel slag.③Carbon emissions and comprehensive global warming potential were showed straw combined application with gypsum slag>straw>straw combined application with biochar>straw combined application with steel slag> control. Carbon emissions and comprehensive global warming potential were increased by 30.42% and 30.18% after straw treatment, respectively. Compared with the straw amendment, the carbon emissions and comprehensive global warming were increased after straw combined application with gypsum slag,however,the carbon emissions and comprehensive global warming potential were decreased after straw combined application with biochar and straw combined application with steel slag. Seen from the comprehensive global warming potential,straw combined application with biochar or steel slag would be a effective supporting measure for carbon sequestration and mitigation of carbon emission in jasmine plantation.
