浅析铁路建设对风景名胜区景观敏感性影响——以新建和顺至邢台铁路为例

Study on Impact of Railway Construction on the Sensitivity of Scenic Area——Taking the Newly Built Railway from Heshun to Xingtai as the Example

本文分析了新建和顺至邢台铁路对太行大峡谷国家级风景名胜区景观敏感性的影响,通过景观阀值计算显示拟建线路所经过风景名胜区域的景观敏感性得分10分、景观阈值得分21分,景观环境质量等级为Ⅱ级,即中度脆弱区,能够容忍轻度人类扰动。工程实施后,项目区景观敏感性增加、景观阈值减低,原有景观将被以铁路运输为主体的交通景观所取代,需在工程选线、软质景观建设等优化设计以减轻工程建设对重要生态敏感区的影响。

：This paper analyzed the impact of railway constmction on the sensitivity landscape of Taihang Grand Canyon National Sct;nie Area. Threshold calculation showed that the sensitivity score of the scenic area was 10 in the assessment area,the landscape threshold score was 21 ,and the environmental quality was grade II,which was the moderate vulnerable area and can tolerate mild human disturbance. After the implementation of the railway project, the sensitivity of the impact area was increased, meantime, the threshold value of the landscape was reduced, and the original landscape would be replaced by the railway transport works. It was necessary to choose an optimal line and the soft landscape factors should be applied in design process in order to reduce the impact of engineering construction on the significant ecological sensitive area.
