摘要
研究以混合建筑再生骨料、红砖和砾石为填料,菖蒲、香蒲、鸢尾、芦苇、美人蕉、再力花、风车草为供试植物,利用层次分析法,构建了基于植物生长特性、生理特性、水质净化效果和经济成本为准则层的人工湿地植物评价体系.结果表明,对4 个准则层进行排序为水质净化效果(0.6144)>生长特性(0.1727)>经济成本(0.1187)>生理特性(0.0942);在净化效果中,4 个因子的权重排序为 TN(0.3050)= TP(0.3050)>氨氮(0.2769)>CODCr(0.1131).生长特性中风车草得分最高(0.585),鸢尾得分最低(0.229);生理特性中芦苇得分最高(0.410),鸢尾得分最低(0);净化效果中风车草得分最高(2.858),菖蒲和再力花得分最低(1.361).根据该评价体系,7 种植物的综合排序依次为风车草、香蒲、芦苇、美人蕉、鸢尾、菖蒲、再力花.为充分发挥植物在湿地中的作用,可选取综合排序前 3 的植物用于影响因素的研究.
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.
