In this paper,based on the different vegetation area occupied by the traffic capacity expansion project of Litang-Qinzhou railway,the vegetation biomass losses of cropland,forest land,and grassland were analyzed quantitatively.The results showed that the vegetation area occupied by the project was 308.6 hm2,of which cropland,forest land and grassland accounted for 140.5 hm2,117.2 hm2 and 50.9 hm2,respectively.During the 2 year construction period,the total vegetation biomass loss would be 35 607.9 t,of which 4 792.7 t was cropland vegetation loss(13.5%),29 888.3 t was forest land vegetation loss(83.9%),and 926.9 t was cropland vegetation loss(2.6%).294.3 t vegetation biomass would be compensated in the early stage after the vegetation restoration measures took effect, such as slope vegetation protection and stations afforestation.
