摘　　要：分析了国内各区划系统的目的、影响因素及指标,以《铁路绿色通道建设指南》为基础,结合铁路绿色防护特点及环境概况,提出了铁路路基绿色防护的区划方案。该方案遵循了气候区、自然区及生态区区划工作中普遍运用到的区划原则,提出了以气候、地貌及植被和水资源分布为主导因素,以温度及干燥程度、地貌及植被和有无灌溉条件为主要指标的二级区划系统,并推荐了干旱区及过干旱区的适宜植被。旱区铁路路基绿色防护区划方案对旱区铁路绿色通道建设有一定的促进作用,并为制定防护区划的细化方案及采取相应的工程措施奠定了基础。This paper analysis the purpose,influence factor and index of division in different academic disciplines.A green protection regionalization plan for railway subgrade is proposed based on construction guide for green space attached of railway engineering,and combined with the characteristic and the environmental profile of railway green protection.This plan followed the common division principles used in the climatic,natural,and ecological regionalization,and proposed a two level division system.The primary factors of the division system are climate,landform and vegetation,and water resources distribution.And the key indicators are temperature and drying degree,landform and vegetation,and irrigation condition.The suitable plants for arid area and excessive arid area based on the regionalization plan were recommended.The green protection regionalization improved the construction for green corridor of railway and laid the foundation for the further work.
