- 摘要:
- 为研究植物根系对天然气管道防腐层的影响，通过对内蒙古地区天然气管道周围5 m范围内植物种类和生态类型的调研,确定9处典型开挖点。开挖的9处中有1处白桦树根系对防腐层产生明显压痕,其他8处暂未对管道防腐层产生明显影响。研究结果表明，植物根系对防腐层的影响因素为树种、胸径、管道埋深、植物与管道相对距离、生态类型；植物种类不同,根系生长特征有很大区别;距离管道越近，管道埋深越浅,管道防腐层受影响风险越大;土壤含水率越高,植物根系分布越靠近地表。根据研究结果制定适用于内蒙古地区的植物风险等级和巡查风险目录,可为植物的种植和处置以及管道防腐层保护提供参考。
Through the investigation of plant species and ecological types within 5 m of natural gas pipeline in Inner Mongolia,9 typical excavation sites were selected to study the influence of plant roots on the anticorrosive layer of natural gas pipeline. Among the 9 excavation sites,1 site with birch tree roots showed obvious indentation on the anticorrosive layer, while the other 8 sites had not yet caused any significant influence on the anticorrosive layer. Research results indicate that factors affecting the plant roots to the anticorrosive layer include tree species, diameter at breast height pipeline buried depth, relative distance between plants and pipeline, ecological type, and environment. Root growth characteristics vary significantly among different plant species. The closer to the pipeline and the shallower the pipeline buried depth, the greater the risk to the anticorrosive layer. The higher the moisture content, the more likely plant roots are to concentrate near ground surface. According to this research and analysis, plant-related risk classification and inspection risk catalogue specific to the Inner Mongolia region were developed to guide vegetation management and control measures and provide reference for the protection of corrosion control layer of pipelines.
