【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。更多还原

【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.更多还原
