山区公路路幅布设与生态环境保护

摘要

Research purposes: In recent years, many roads have been built in coteau in China.Freeway construction affects the environment seriously.This paper discusses the relation between the transect arrangement of the coteau freeway and environment to reduce the influence of coteau freeway construction on the ecological environment.Research conclusions:When the freeway is needed to be constructed in coteau,it is necessary to do the research on the coordinated relation between the freeway construction in coteau and ecological environment.This paper analyzes the relation between transect arrangement of coteau freeway and ecological environment.The evaluation model is established with the objective and subjective synthetic approaches to determine the weights integrating the environment, society and economy factors for choosing the transect arrangement plan which benefits environment protection and economy to reduce the influence of the freeway construction in coteau on the ecological environment.%研究目的:近年来,我国高速公路建设比较多.高速公路建设,特别是山区高速公路建设对生态环境影响较为严重.本文通过探讨山区公路路幅布设与生态环境的关系,来减小山区公路建设对生态环境的影响.研究结论:在山区高速公路快速建设的同时,我们很有必要对高速公路建设与环境生态协调问题进行研究.本文详细分析了山区高速公路路幅方案与生态环境之间的关系,运用主客观综合评价法综合生态环境、社会、经济等方面因素建立评价模型,评选既能保护生态环境又经济合理的路幅方案,目的是通过山区路幅布设研究来减小山区公路建设对生态环境的影响.
