| 中文摘要: |
| 抗生素能够影响土壤微生物群落结构和功能多样性从而影响微生物介导的氮循环过程，改变土壤环境中各种氮素形态和脲酶活性，进而影响土壤氮循环。为了量化分析土壤中抗生素对土壤氮循环的影响，本研究从中国知网和Web of Science数据库收集了2002年1月—2024年3月共62篇相关文献，从中提取相关数据用R语言进行Meta分析，综合不同时空甚至结论相悖的研究结果，得出更一般、普遍的研究结论，揭示抗生素对土壤氮素循环的影响机理。结果表明：四环素类（TCs）、磺胺类（SAs）和喹诺酮类（QNs）三类抗生素会抑制土壤脲酶活性、amoA-AOA和amoA-AOB，促进土壤NH3挥发，降低氨氧化速率，减缓土壤氮素循环。TCs降低了土壤NH4+-N、NO2--N和NO3--N含量，而SAs和QNs提高土壤NH4+-N含量，降低了土壤NO2--N和NO3--N含量。基于以上研究，三类抗生素总体抑制氨化作用、硝化作用和反硝化作用中的各类指标；但SAs增加NH4+-N、nirK、nirS和nosZ，促进NH3排放；QNs增加NH4+-N和促进N2O排放，这与抗生素的类型及抗生素类型影响的相关微生物有关。 |

| Antibiotics are used heavily in livestock and poultry farming, but up to 90% of antibiotics are not fully absorbed by animals and are excreted in the urine and enter the soil with fertilization. Antibiotics can affect the structure and functional diversity of soil microbial communities, thus affecting the microbial mediated nitrogen cycle process, changing various nitrogen forms and urease activity in the soil environment, and thus affecting the soil nitrogen cycle. In order to quantitatively analyze the impact of antibiotics in soil on soil nitrogen cycling, this article collected a total of 62 relevant literatures from China National Knowledge Infrastructure（CNKI）and Web of Science from January 2002 to March 2024, and relevant data were extracted for meta-analysis using R language. By combining the results of different time and space studies and even with contradictory conclusions, more general and general research conclusions were drawn to reveal the mechanism of the effects of antibiotics on soil nitrogen cycle. The results showed that tetracyclines（TCs）, sulfonamides（SAs） and quinolones（QNs）antibiotics would inhibit the activity of soil urease, amoA-AOA and amoA-AOB, increase the volatilization of soil NH3, and decreased the ammonia oxidation rate, slow down soil nitrogen cycling. TCs decreased the contents of NH4+-N, NO2--N and NO3--N in soil, while SAs and QNs increased the contents of NH4+-N and decreased the contents of NO2--N and NO3--N in soil. Based on the above research, the three types of antibiotics overall inhibit various indicators of ammonification, nitrification, and denitrification; But SAs promote NH4+-N, NH3, nirK, nirS, and nosZ; QNs promote NH4+-N and N2O, which is related to the types of antibiotics and the associated microorganisms affected by antibiotic types. |
