摘要
为了筛选出适应性强、繁殖速度快、成活率高的藤本植物,实现高速公路石质边坡快速复绿和生态恢复的效果,更好地服务广西生态文明建设,以广西崇靖和崇水高速公路为试验地,根据试验地现场调查和层次分析相结合的方法,按景观价值、适生性能、繁育难度、应用潜力以及经济性等4个因子,设置20个指标针对30种藤本植物在高速公路边坡绿化的效果与潜力进行评价与筛选。藤本植物的评价等级划分标准,结合实地调查与综合评价的分值来划分,分值≥4.00分为Ⅰ级,3.50~3.99分为Ⅱ级,3.00~3.49分为Ⅲ级。结果表明:Ⅰ级的藤本植物为囊托羊蹄甲、爬山虎、三角梅小叶浅紫、木麒麟、使君子、鸡屎藤、翅茎白粉藤、炮仗花、菰腺忍冬、常春油麻藤,为适应性较强的藤本植物;Ⅱ级的藤本植物为蒜香藤、金钟藤、凌霄、山蒟、珊瑚藤,为适应性强的藤本植物;其他均为Ⅲ级,适应性一般。
To better screen out Guangxi native vines with high adaptability,fast reproduction speed,and high survival rate,to achieve rapid greening and ecological restoration of highway stone slope,and to better serve the ecological-civiliz-ation-construction of Guangxi.Taking Chongjing Expressway and Chongshui Expressway in Guangxi as test sites,According to the method of field investigation and AHP,20 indexes were set to evaluate and screen the greening effect and potential of 30 species of lianas on highway slope according to four factors,including landscape value,fitness,breeding difficulty,application potential,and economy.The evaluation grade of lianas was divided according to the field investigation and comprehensive evaluation scores.The scores of lianas≥4.00 were classified as gradeⅠ,3.50~3.99 as gradeⅡ,and 3.00~3.49 as gradeⅢ.The results showed that:The gradeⅠlianas were the most adaptable lianas,such as Bauhinia touranensis Gagnep,Parthenocissus tricuspidata(SIB.&Zucc.)Planch,and Bougainvillea glabra Choisy'Elizabeth Angus',Pereskia aculeata Mill,Quisqualis indica L,Paederia scandens(Lour.)Merr,Cissus hexangularis Thorel ex Planch,Pyrostegia venusta(Ker-Gawl.)Miers,Lonicera hypoglauca Miq,Mucuna sempervirens Hemsl;The lianas of gradeⅡwere Mansoa alliacea(Lam.)A.H.Gentry,Merremia boisiana(Gagnep.)Ooststr,Campsis grandiflora(Thunb.).Schum,Piper hancei Maxim,Antigonon lepto-pus Hook.et Arn,which was highly adaptable;All the others wereⅢlevel,with general adaptability.
