Carbon Sequestration and Carbon Release in Vegetation and Soil Around Railway and Influencing Mechanism of Various Factors
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.
