内蒙古集通铁路防护林构建技术研究

Technology of Constructing Protective Forest along Jitong Railway In Inner Mongolia

本项研究根据集通铁路所处的地理位置及所受沙灾、雪灾、风灾、水灾四大灾害的危害特点 ,以 DK32 8+ 5 0 0～ DK338+ 5 0 0为试验示范区 ,在调查分析当地自然条件的基础上 ,对沿线立地类型进行了科学的剖析和划分。针对铁路安全运输生产的要求 ,采用多种造林技术措施 ,乔灌草相结合 ,阻固造封并举 。

Based on geographic position of Jitong railway and characters of sand, snow, wind and flood, taking DK328+500～DK338+500 as demonstrative district, on the basis of investigating and analyzing local natural conditions, the project has analyzed and divided the site types along the railway. According to the demands of railway's safe transportation and production, several kinds of forestation technology have been adopted to recover vegetation along railway.
