摘　　要：为了对生态环境质量进行综合评价,运用环境景观格局综合评价方法,对西成客运专线西安至江油段铁路段划分出9个不同的生态环境类型。西城客运专线铁路的修建对沿线的耕地和林地影响较大,对水地和草地的影响较小,是西成客运专线施工和后期生态恢复中主要评价和研究的内容。环境景观综合评价表明,横贯中国南北自然地理分界线秦岭的西城客运专线的修建对沿线景观环境影响程度较轻、铁路与沿线景观较为协调,表明西城客运专线设计比较合理。同时,评价的结果也说明,采取恰当的工程措施可以最大限度地减小对自然生态环境的破坏。Environmental landscape pattern and comprehensive evaluation methods were used to make a comprehensive assessment of eco-environment quality by dividing the eco-environment types of Xi'an-Chengdu passenger dedicated line into 9 different types. The construction of Xi'an-Chengdu passenger dedicated line has the greater impact on the farmland and woodland,and the smaller impact on water and grass along the line,which are the main point of assessment and research in present construction and post-ecological restoration. Comprehensive evaluation indicates that the impacts on landscape environment caused by construction of the railway which traverse Qinling Mountains,the natural geographical boundary between north and South China,are slight. Railway is harmonious with landscapes along the line. The results showes that design of the railway was reasonable. The impacts on the environment caused by the construction are slight. At the same time,the results of assessment also indicate that the use of appropriate engineering measures can minimize the damage on the natural environment.
