【摘要】 生物炭在土壤应用过程中,对土壤碳库含量以及碳封存稳定性的影响受到广泛关注。本文综述生物炭在土壤碳库含量和碳封存稳定性方面的最新研究进展。明确生物炭的添加可增加土壤中的有机质,显著提高土壤中的碳储存量。此外,通过改善土壤的理化性质,提高土壤的持水性和通气性,增强土壤碳的封存稳定性。通过生物炭对土壤中微生物群落及微生物代谢机制的影响对,土壤碳封存稳定性的辅助作用。尽管生物炭的应用对土壤碳库含量和碳封存稳定性具有潜在的益处,但其影响因素和机制仍存在一定的争议。生物炭的品质、添加量和土壤类型等因素可能会影响其对土壤碳库含量和碳封存稳定性的影响效果。因此,未来的研究应重点关注这些因素,并进一步深入探究生物炭在不同环境条件下的作用机制。更多还原

【Abstract】 The effects of biochar on soil carbon pool content and carbon sequestration stability during soil application have received widespread attention.This paper summarizes the recent research progress of biochar on soil carbon pool content and carbon sequestration stability.It is clarified that the addition of biochar can increase the organic matter in soil and significantly improve the carbon storage in soil.In addition,it enhances the stability of soil carbon sequestration by improving the physical and chemical properties of the soil and increasing the water holding and aeration properties of the soil.The effect of biochar on microbial communities and microbial metabolic mechanisms in the soil is complementary to the stability of soil carbon sequestration.Despite the potential benefits of biochar application on soil carbon pool content and carbon sequestration stability,the influencing factors and mechanisms remain somewhat controversial.Factors such as the quality of biochar,the amount of addition,and soil type may influence its effect on soil carbon pool content and carbon sequestration stability.Therefore,future research should focus on these factors and further explore in depth the mechanism of biochar’s action under different environmental conditions.更多还原
