【摘要】 为评价生物滞留措施中植物的适宜性,在层次分析法的基础上,通过专家咨询,提出了应用于路面径流消纳的生物滞留措施中植物选择的3个评价因素为生态效益、景观效益、经济效益,10个评价指标为耐旱性、耐涝性、耐污性、耐盐性、耐寒性、耐荫性、观赏性、乡土性、购置成本、管护需求,建立了植物评价的层次结构模型。并采用此模型评价了北京市常见的9种地被植物对生物滞留措施的适宜性,得出八宝景天、鸢尾对生物滞留措施的适宜性高,崂峪苔草、萱草、马蔺、紫露草、麦冬、扶芳藤的适宜性较高,千屈菜的适宜性一般。更多还原

【Abstract】 In order to evaluate the suitability of plants in the bioretention measure,the analytical hierarchy process( AHP) and expert consultation were used,and three evaluation factors of ecological benefit,landscape benefit and economic benefit,as well as ten evaluation indexes of drought tolerance,flooding tolerance,runoff pollution tolerance,salt tolerance,cold tolerance,shade tolerance,ornamental value,indigene,cost and maintenance need were proposed,thus the hierarchical model used for plant evaluation in bioretention of road runoff was constructed. The suitability of nine common ground cover plants in Beijing to bioretention was assessed using this model,and it was found that Sedum spectabile and Iris tectorum had high suitability,and Carex giraldiana,Hemerocallis fuava,Iris lactea,Tradescantia albiflora,Ophiopogon japonicas and Euonymus fortunei had relatively high suitability,and Lythrum salicaria had common suitability.更多还原
