基于层次分析法的建筑再生骨料人工湿地植物评价模型构建与应用
Plant Evaluation Modeling and Application Construction Recycled Aggregate Constructed Wetland Based on Analytic Hierarchy Process
摘要
Abstract
In this study,mixed construction recycled aggregates,red bricks and gravels were used as fillers,Acorus calamus L.,Typha orientalis Presl,Iris tectorum Maxim.,Phragmites australis(Cav.)Trin.ex Steud,Canna indica L.,Thalia dealbata Fraser and Cyperus involucratus Rottboll were used as test plants.A constructed wetland plant evaluation system based on plant growth characteristics,physiological characteristics,water purification effect and economic cost was constructed using analytic hierarchy process(AHP).Results showed that the four criterion layers were ranked as water purification effect(0.6144)>growth characteristics(0.1727)>economic cost(0.1187)>physiological characteristics(0.0942).The weights of the four purification factors were ranked as TN(0.3050)= TP(0.3050)>ammonia nitrogen(0.2769)>CODCr(0.1131).The highest score for growth characteristics was 0.585(Cyperus involucratus Rottboll)and the lowest score was 0.229(Iris tectorum Maxim.);the highest score for physiological characteristics was 0.410(Phragmites australis(Cav.)Trin.ex Steud)and the lowest score was 0(Iris tectorum Maxim.);the highest score for purification effect was 2.858(Cyperus involucratus Rottboll)and the lowest score was 1.361(Acorus calamus L.and Thalia dealbata Fraser).According to the evaluation system,the comprehensive ranking of the seven plants was Cyperus involucratus Rottboll,Typha orientalis Presl,Phragmites australis(Cav.)Trin.ex Steud,Canna indica L.,Iris tectorum Maxim.,Acorus calamus L.and Thalia dealbata Fraser.To take full advantage of the role plants play in wetlands,the top three plants in the composite ranking can be selected to study influencing factors.关键词
