摘要
研究目的:我国现行铁路建设对临时工程用地的土地复垦没有统一的设计技术规范和因地制宜的可借鉴的设计思路。本文主要从铁路建设临时用地原有生态环境功能恢复的角度,通过实际案例剖析,旨在结合区域气候特点和地形地貌为铁路等大型临时工程建设后期的土地生态功能恢复以及复垦土地资源的综合利用提供可借鉴的思路。研究结论:铁路建设过程中除路基、站场等永久占地外,对于取弃土场、便道、施工营地等临时工程对沿线土地功能的破坏,通过结合不同地类及地形地貌采取相宜的土地复垦技术方法和措施能较好地恢复原有土地的生态功能。本文提出的表土剥离临时挡护措施、土地复垦区的排灌系统及生态植被系统等工程技术方案在工程中有较好的实际应用效果,其措施和方法对恢复和改善铁路沿线的生态环境和景观环境都起到了一定的作用。
Research purposes： There are no design codes and design thoughts for reclamation of land temporarily used for railway construction. This paper describes what was done for reclamation of the land used for construction of Guiyang - Guangzhou Railway and points out the land reclamation should be done according to the local conditions for the purpose of providing reference to the similar work. Research conclusions：The ecological functions of the land destroyed in the course of railway construction, such as the lands for storing waste soil, for temporary path, for temporary house and for temporary engineering can be restored by adopting the relative reclamation technology and taking relative measures, such as removing surface soil, building irrigation system and installing vegetable layer. These technologies and methods are very useful for restore the ecological function of the destroyed land along the railway.
