浅谈辽宁山区高速公路绿化设计思路及树种选择

A Brief Introduction on Greening Design of Highways in the Mountain Region of Liaoning Province and Tree Species Selection

结合辽宁省辽东山区高速公路生态环境、气候、地形等自然情况,全面阐述了辽东山区高速公路服务区、收费站、互通立交区、中央分隔带、路堤坡脚、路堑边坡、隧道洞口等区段的绿化设计思路及常用树种,并根据高速公路树木生长的立地条件和地形地势等,"因地制宜、适地适树"的原则进行工程防护,保证了山区高速公路的"畅、安、舒、美"。

Combined with the ecological environment,climate and terrain of the mountain regions in the eastern part of Liaoning Province,the greening designs on highway service area,toll- station,interchanges,separation zones,slope toe of the embankment,side slope of the cutting as well as the tunnel portal are introduced and the commonly used tree species are selected. Besides,based on the growing conditions of the trees and the terrain,protective projects are implemented in line with the principle of ＂ Prior to local conditions and prior to proper tree species＂,which will definitely guarantees the smooth,safety,comfort and beauty of the highways.
