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。
In order to carry on the comprehensive appraisal to the ecological environment quality, using the comprehensive evaluation method of the environmental landscape pattern, divide 9 different ecological environment types into the railway section of Xi’an-Jiangyou section of Xicheng Passenger Dedicated Line. The construction of the Xicheng Passenger Dedicated Railway has a great influence on cultivated land and forestland along the line, and has little impact on water and grassland. It is the main evaluation and research in the construction and later ecological restoration of Xicheng Passenger Dedicated Line. Comprehensive assessment of the environment landscape shows that the construction of the Xicheng passenger dedicated line across the Qinling Mountains bounding the natural geographical boundaries between North and South of China has less impact on the landscape environment along the railway line and more harmonious coordination between the railway and the railways along the line, indicating that the design of the Xicheng Passenger Dedicated Line is reasonable. At the same time, the evaluation results also show that proper engineering measures can minimize the damage to the natural environment.
