摘要：铁路施工对周边植被和土壤等环境造成较大扰损，对陆地生态系统与大气间的碳平衡造成破坏。因此，厘清铁路周边植被和土壤对CO2的吸收、固定、释放机制，对于促进碳吸收、碳储存和减缓碳释放具有重要意义。作者基于国内外历年发表的文献阐述了植被与土壤固碳和释碳的机制及影响因素，并对铁路周边固碳增汇提出了几点建议，以期为铁路周边土壤与植被的固碳增汇提供一定的参考和借鉴。

Abstract: Railway construction will cause great disturbance to surrounding vegetation and soil and damage the carbon balance between terrestrial ecosystem and atmosphere. Therefore, it is of great significance to clarify the mechanism of CO2 absorption, fixation and release by vegetation and soil around railway for promoting carbon absorption, carbon storage and mitigation of carbon release. Based on the literature published at home and abroad over the years, this paper expounds the mechanism and influencing factors of carbon sequestration and carbon release of vegetation and soil, and puts forward some suggestions on carbon sequestration of soil and vegetation around railway.
Keywords: railways, soil, vegetation, carbon sequestration, carbon release
