摘要
铁路建设生态影响主要体现在生态敏感区受损、生态系统服务功能降低、生态景观破碎加剧等方面,本文通过剖析基于全线生态影响的设计方案评价的内涵与特点,采用三角模糊数、生态系统服务功能价值理论等技术方法,建立了基于全线生态影响的方案评价模型,可从全线生态保护角度,为铁路设计方案的优化评价提供参考依据,对于路域生态保护决策提供了新思路。
Ecological sensitive area damaged, ecosystem services value decreased and ecology landscape crushing aggravation is the main ecological impact causing by railway construction. The paper analyzed the characteristics of scheme comparison Based on the whole railway line ecological impact and took some effective evaluation methods such as triangular fuzzy number and ecosystem services value theory to establish an evaluation model of ecology impact evaluation. It could provide reference for optimization railway scheme and provide a new idea for railway ecology protection decision from the point of view of the whole railway area ecology protection.
