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。
In order to evaluate the suitability of plants in bio-retention measures, three evaluation factors of plant selection in bio-retention measures applied to road runoff elimination were put forward on the basis of analytic hierarchy process (AHP) through consultation with experts: ecological benefits, landscape benefits, Economic evaluation, 10 evaluation indexes were drought tolerance, waterlogging tolerance, soil resistance, salt tolerance, cold tolerance, shade tolerance, ornamental, rustic, purchase cost, management and protection requirements, and established the level of plant evaluation Structural model. This model was used to evaluate the suitability of nine kinds of ground cover plants in Beijing for bioretention measures. The results showed that there was a high suitability of biotremor in Ipomoea aquatica, Iris latifolia, Iris lactea, Fragrant grass, Radix, Euonymus fortune higher suitability, Lythrum suitability in general.
