| 摘 要： | 废弃物的农业资源化是当前研究的热点之一,但将其应用于环境效应评价还鲜见报道.通过实验测定,探讨了秸秆及秸秆分别配施石膏渣、生物炭、炉渣对福州茉莉园碳排放及其综合增温潜势的影响.结果表明:与对照相比,施加秸秆CH_4排放通量提高了20.05%;与秸秆处理相比,秸秆配施石膏渣和秸秆配施生物炭不同程度地提高了CH_4排放通量,而秸秆配施炉渣的CH_4排放通量则有所降低.与对照相比,施加秸秆CO_2排放通量提高了30.45%;与秸秆处理相比,秸秆配施石膏渣提高了CO_2排放通量,而秸秆配施生物炭和秸秆配施炉渣的CO_2排放通量均有所降低.CO_2对茉莉园碳排放和综合增温潜势贡献较大,碳排放和综合增温潜势均表现为秸秆配施石膏渣秸秆秸秆配施生物炭秸秆配施炉渣对照,秸秆处理的碳排放和增温潜势较对照分别提高了30.42%和30.18%,秸秆配施石膏渣较秸秆处理提高了碳排放和综合增温潜势,而秸秆配施生物炭和秸秆配施炉渣的碳排放和综合增温潜势均有所降低.从温室气体综合增温潜势来看,秸秆配施生物炭或炉渣可作为茉莉园固碳减排的有效配套措施.

| Abstract: | 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 CH4 emission fluxes increased by 20.05% after straw amendment with gypsum slag, biochar, however, decreased when amended with steel slag.2CO2 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. |
