| Abstract: |
| ［ Purpose ］ The life cycle assessment（LCA）method is currently an important tool for evaluating the environmental impact of the product production or service process，and it is gradually getting more applications in agricultural research. Our study introduces this method，reviews the current development of life cycle assessment software and databases，analyzes the application potential of this method in agricultural production carbon accounting，and provides technical support for our country’s agricultural carbon emission reduction and sustainable development.［Method ］ Our study introduces the development status of life cycle assessment from multiple perspectives through database literature retrieval and network data collection.［Result ］ The results showed that：at present，our country has achieved some outcomes in the research and application of LCA methods and LCA in agriculture，which filling the gaps in LCA software and databases. However，the LCA has broad application prospects in agriculture，and further research needs to be further developed.［Conclusion ］ Follow-up work should continue to complete our country’s LCA basic database，collect and supplement country's relevant data，strengthen the research and development of localized software tools，continue to promote the development and application of LCA at the agricultural level，and establish an environmental impact assessment system in line with our country’s national conditions. |
