摘要
生态护坡技术应用于生态敏感区,可以有效地解决工程活动带来的生态问题.为了保护铁路沿线的生态敏感区,促进工程建设与生态环境的协调发展,实现经济社会与自然环境的长足发展.本文以四川省境内的某铁路段为研究区,分析了铁路沿线的气候、工程地质条件及植被生长发育状况,建立了基于层次分析法的植被选型模型,总结了适用于研究区土质边坡生态恢复的植被.结果表明:基于层次分析法建立的植被选型模型具有良好的应用效果.草本植物中优选物种为狗牙草、草木犀、羊胡子草、结缕草、高羊茅;灌木中优选物种为紫穗槐、火棘、沙棘、多花木兰、马桑;乔木中优选物种为青㭎、构树、冷杉、马尾松、柳杉;藤本植物中优选物种为葛藤、三叶木通.基于优选植被进行的边坡生态恢复取得了良好的生态效应.
Abstract
The application of ecological slope protection technology in ecologically sensitive areas can effectively solve ecological problems caused by engineering activities.In order to protect the ecologically sensitive areas along the railway,and promote the coordinated development between the engineering construction and ecological environment devoting to balance the economy society and natural environment.We analyzed the climate,engineering geological condition and vegetation growth along the way,and established a vegetation selec-tion model based on AHP,summarized the revegetation during the ecological restoration which is suitable for the soil slopes in this area.The results show that the vegetation selection model based on AHP produces a favorable application effect.The dominant herbs are the Bermuda grass,grass rhinoceros,fox grass,zoysia and tall fescue;the dominant shrubs are the amorpha,fire buckthorn,sea buckthorn,multi-flowered magnolia,and masang;the dominant trees are aoka,paper mulberry,fir,masson pine and cedar;the dominant vines are kudzu and cloverleaf.The slope ecological restoration based on the optimal vegetation has generated a great ecological effect.
