郑西客运专线建设的植被影响分析

Effects of construction of Zhengzhou-Xi'an passenger dedicated railway on vegetation

基于郑西客运专线建设工程所占用的各类植被面积,对工程造成的农田、林地和荒草地的生物量损失进行了估算。结果表明,该工程占用的植被面积为1526.12hm^2,其中农田、林地和荒草地分别为1240.17hm^2、232.99hm^2和52.96hm^2,工程在4年的施工期内造成的生物量损失共计65081.82t,其中农田植被生物量损失为30535.64t,占46.9%,林地植被生物量损失为33077.59t,占50.8%,荒草地植被生物量损失为1468.59t,占2.3%。随着边坡防护、站场绿化等植被恢复措施的实施,初期每年可补偿的植被生物量为1220.90t。

Based on the different vegetation area occupied by the construction of Zhengzhou-Xi＇an passenger dedicated railway, theauthors 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.
