摘要
铁路的绿色通道可以起到稳固边坡、保持水土、美化路容等作用。采用工点分区和多因素影响分析等方法,对某铁路的绿色通道设计进行研究。根据适用的绿化形式和基本原则,将该新建铁路分为路基、桥梁和站区三类工点,分别采用灌乔结合、灌草结合和以观赏性植物为主的绿化原则;在苗木种类和建植方式选择方面,采用对比分析的研究方法,选取了与既有绿化有机统一的植物种类。研究表明:铁路绿色通道建设应根据工点类型选择相应的绿化形式,路基的绿化设计应根据边坡高度以及是否有排水沟进行有机调整,苗木种类和建植方式应与当地自然环境和既有绿化有机结合。
The green channel of railway plays a role of stabilizing slope,maintaining water and soil and beautifying the road. This paper studied the design of green channel of a railway section through site partitioning and multi-factor impact analysis. The new railway section was divided into three types of work sites: subgrade,bridge and station area,according to the applicable greening forms and principles. The green principles including combination of shrub and arbor,combination of shrub and grass,and ornamental plant dominated were adopted,respectively. A comparative analysis method was adopted in the selection of seedling species and planting methods,and the plants organically united with existing greening were selected. The results show that the green channel construction of the railway should choose the corresponding greening patterns according to the working types thereof,the greening design of the subgrade should be organically adjusted according to the height of the slope and whether there is a drainage ditch,and the selection of seedling species and planting method should be combined with the local natural environment and the existing greening.
