高速公路植物隔离栅的应用研究现状与展望
Reviews on Researches of Application and Prospect of Highway Hedgerow Network
-
摘要: 植物隔离栅就是以有刺植物为主体材料、宽幅1m 左右，进行高速公路隔离防护的设施，沿着高速公路路幅外围的边沟外侧、公路红线范围内侧用地边界上，将高速公路与农田、村庄、城镇、山林等隔离分开构成一道绿色的屏障型廊道，以取代金属为主体材料的隔离栅。我国高速公路隔离栅需求大，文章针对金属隔离栅易生锈损毁、管理养护成本高、景观效果差的现状，提出了植物隔离栅在隔离阻断、生态保育、景观提升、环境教育、养护管理等方面具有的优良特性。研究认为，以往的植物隔离栅在植物品种选择、栽植技术、抗旱性研究、综合效益评价、相关技术规范等方面已经取得了一定的研究进展。提出了做好植物隔离栅建设与隔离防护功能的衔接、现有金属防护网与新栽植物篱的衔接及科学研究与工程实践的衔接三个方面的建议与展望，对高速公路植物隔离栅的推广应用具有积极意义。Abstract: Presentation was made on highway hedgerow network at home and abroad in terms of concept, special functions. Reviews were carried outon researches on application of hedgerow network at early time, as well as on species selection, plantation and distribution of different plants, droughtresistance, comprehensive evaluation and technical specification. Suggestions and prospects were put forward for better development ofhedgerow network.
