Alignment Standard Combination and Ecologic Environmental Protection of Mountainous Area

分析了山区高速公路线形指标组合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、交通安全、运行的经济成本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指标组合,目的是通过山区公路线形标准组合研究来减小公路建设对山区生态环境的影响。

The article analyzes the relationship between the alignment index combination and ecological environmental protection of mountainous expressway. The subjective and objective comprehensive assessment method synthesizing the factors of ecological environment, traffic safety and operating economic cost is used to establish the assessment model to evaluate and select the index combination not only to protect the ecological environment, but also to be economic and reasonable. The purpose is to decrease the influence of highway construction on the mountainous ecological environment through the study on the alignment standard combination of mountainous expressway.
