农业土壤碳库研究进展

Research Progress of Agricultural Soil Carbon Pool

降低CO_(2)排放对于生态环境与经济发展具有重要意义。农业土壤固碳具有较大的成本效益是缓解温室效应的主要途径。在“碳达峰、碳中和”战略背景下加强农业土壤碳库研究,重视土壤碳固存与碳排放,对于实现“双碳”目标亦有重要意义。主要从土壤碳库的存在形式、不同管理措施对农田土壤碳库的影响以及稳定碳同位素技术在农业土壤碳库研究中的应用三个方面对国内外的研究进行综述,旨在为进一步探究农业土壤固碳减排的有效措施提供重要的线索和依据。

Reduction of CO_(2) emission is of great significance to our ecological environment and economic development.Agricultural soil carbon sequestration has significant cost-effectiveness and is the main way to alleviate the greenhouse effect.It is also of great significance to strengthen the research on agricultural soil carbon pool,and to attach importance to soil carbon sequestration and emission for the realization of the goal of“carbon peak and carbon neutrality”.The existing form of soil carbon pool,the influence of different management measures on farmland soil carbon pool and the application of stable carbon isotope technology to the study of agricultural soil carbon pool were reviewed to provide important clues and basis for further research on effective measures of carbon sequestration and emission reduction in agricultural soil.
