摘要
通过对秦岭地区生态环境现状、敏感性及影响因素分析,结合该区域既有铁路建设对生态环境影响经验总结及铁路客运专线特点,确定了西成客运专线秦岭山地环保选线的基本思路及原则。对西成客专西安北至汉中段不同通道方案环境影响进行评价,结果表明:涝峪经佛坪(AK)方案避开了秦岭山区集中连片的保护区域,引线及越岭隧道工程涉及的生态敏感区少且线路短顺,对秦岭生态环境影响最小。
Through analysis of eco-environmental status, sensitivity and impact factors of Qinling mountains, a number of construction projects of the Xi' an to Chengdu Passenger Dedicated Railway were proposed. Combination of experience of railway construction in the region, the impact on the ecological environment, the basic idea and principle of construction projects were defined. The comparative analysis of environmental impact of construction options showed that: because of avoiding concentrate protection region, the lead and CROSSLINE tunnel project involved few ecologically sensitive areas, Laoyu-Foping(AK) project had least eco-environmental impact to Qinling mountain.
