摘　　要：以17种挺水植物为研究对象,对挺水植物进行驯化处理,随后移植在模拟生活污水中培养,在不同的时间段内采集水质,并对水质中的总氮、总磷、氨氮和化学需氧量以及pH进行监测,采用灰色关联度分析评价挺水植物的综合净化水质的能力。结果表明,不同的挺水植物对单个水质指标的去污能力差异较大;灰色关联度分析17种挺水植物综合去污能力优等的有3种,分别是旱伞草、紫芋和灯芯草;综合去污能力良好的有6种,分别是海寿花、水葱、溪荪、水生美人蕉、花叶芦竹、再力花;综合去污能力中等的有5种,分别是香蒲、水芹、慈姑、纸莎草、泽泻;综合去污能力较低的有3种,分别是千屈菜、黄菖蒲、菰。初步筛查出9种挺水植物具有良好的综合去污效果,试验结果可为后续小微湿地水生植物示范与推广提供基础数据。In this paper,17 kinds of emergent plants are taken as research objects,and they are domesticated,and then transplanted into simu⁃lated domestic sewage for cultivation.Water quality is collected in different time periods,and the total nitrogen,total phosphorus,ammonia nitro⁃gen,chemical oxygen demand and pH value of water quality are monitored.Grey correlation analysis is used to evaluate the comprehensive puri⁃fication ability of emergent plants.The results showed that the decontamination ability of different emergent plants to a single water quality index was significantly different;according to the grey correlation analysis,three of the 17 emergent plants had the best comprehensive decontamina⁃tion ability,which were Umbrella,Amorphophallus purpureus and Dendrolimus;there are 6 kinds with good comprehensive decontamination a⁃bility,namely,Haishouhua,Shuicong,Xisung,aquatic canna,flowering and leafy asparagus,Zailihua;there are 5 kinds with medium comprehen⁃sive decontamination capacity,namely cattail,water celery,arrowhead,papyrus and alisma orientalis;there are 3 species with low comprehen⁃sive decontamination capacity,namely,Lythrum,Acorus calamus and Zizania latifolia.Nine emergent plants have been preliminarily screened and have good comprehensive decontamination effect.The test results can provide basic data for the subsequent demonstration and promotion of aquatic plants in small and micro wetlands.
