黔张常铁路环境敏感区铁路选线

Selection of Route in the Environmental Sensitive Region of Qianjiang-Zhangjiajie-Changde Railway

研究目的:本文结合黔张常铁路工程和环境敏感区的特点,重点对工程穿越湖南龙山印家界省级自然保护区和湖北省咸丰县二水厂野猫河水库饮用水源地两段重要线路路段进行环境比选,旨在选出一条符合技术标准而又环保的铁路线路。研究结论:(1)在充分收集环境敏感区域资料的基础上,在选线时进行多方案比选,线路必须绕避环境敏感区的核心区,当线路无法绕避环境敏感区的缓冲区时,尽量采用对环境影响较小的隧道或桥梁工程;(2)在项目勘察、设计阶段主动与各级政府环保部门沟通,为了使该铁路的环境影响评价与勘察、设计等工作有机结合起来,必须及时申报、办理环保方面的手续,从而合法地推进该铁路的顺利、快速建设;(3)黔张常铁路环境敏感区选线研究的方法,可为日后中西部此类地区的选线提供理论和实践层面的借鉴与参考。

Research purposes： In this article, the characteristics of environmental sensitive regions in Qianjiang -Zhangjiajie- Changde railway project are taken into consideration. The research tocuses on tlae environmental comparison of the important railway sections which penetrate Longshan Yinjiajie provincial natural reserve of Hunan province and drinking water source of Yemaohe reservoir of the second water factory in Xianfeng county of Hubei province, in order to select a railway route which is environmental benign and satisfies the technique criteria. Research conclusions： （ 1 ） A comparison was made amongst various solutions, on the basis of a sufficient literature survey on the environmental sensitive regions. The core environmental sensitive regions should be circumvented. If penetrating the buffer area of environmental sensitive regions was unavoidable, tunnels or bridges should be adopted in the projects, since the influences on environment would be relatively less. （2） During the project survey and design phase, active communication work for environmental issues with environmental agencies of government were necessary. In order to combine the environmental impact assessment of railway with project survey and design, the formalities of environmental protection must be timely declared. Accordingly, the railway construction could be performed rapidly and legally. （3） The exemplary route selection methods for environmental sensitive regions of Qianjiang -Zhangjiajie -Changde railway can provide both theoretical and practical references for route selections in the mid - west region as such regards.
