Based on the different vegetation area occupied by the construction of Zhengzhou-Xi'an passenger dedicated railway,the authors quantitatively analyzed the vegetation biomass losses of cropland,forest land,and wasted land.The results showed that the vegetation area occupied by the construction was 1526.12 hm2,of which cropland,forest land and wasted land accounted for 1240.17, 232.99 and 52.96 hm2,respectively.During the four year construction period,the total vegetation biomass loss would be 65081.82 t,of which 30535.64 t was cropland vegetation loss(46.9%),33077.59 t was forest land vegetation loss(50.8%),and 1468.59 t was cropland vegetation loss(2.3%).1220.90 t vegetation biomass would be compensated in the early stage after the vegetation restoration measures such as slope vegetation protection,stations afforestation took effect.
