摘要: 京通线奈曼地区铁路沿线有丰富的沙物质来源, 有春旱与大风多风期的一致性, 形成具有严重风沙活动的特有生态条件。在治理铁路沿线沙害中, 采取以植物固沙为主, 机械固沙为辅、乔、莜、苹相结合, 建立阻、固、造、封加速度流沙固定的综合防护体系是行之有效的固沙措施。防护体系建立后, 大约经过5-10年时间, 可形成良好的人工植被防护体系, 使流沙达到固定, 消除线路沙害, 保证列车正常通行的目的。

Abstract: Naiman Section of Jing-Tong railwary, with abundant sandy deposits on both sides and suffer-ring from spring drought, frequent and strong winds, is in an unique ecological condition. It has been proved that a comprehensively protective system which consists of vegetation stabilization and mechanical sandbreak is a successful measure against sand harms to railway. However, the priority is given to the vegetation stabilization and formed into a fixation-block-afforestation-enclosing system comprising of trees, shrubs and grass. During the succeeding 5 to 10 years this protective system would form a better artificial vegetation belt, thus making shifting sand fixed and ensuring smooth traffic of railway.
