摘要:
磷是富营养化水体中的特征污染物，是植物和微生物的主要营养元素。而水体富营养化是水体污染中最为普遍的现象，也是国内外水环境污染治理的难题。本文以生态修复技术为切入点，研究了碟子湖湿地中酸模、蔊菜、稗草、莎草、野生胡萝卜、虉草六种优势植物的生物量和对污水中磷的净化效果，分析了根系和地上部分生物量与污水净化效果之间的关系。根据植被的生长环境条件和植被的自身特性探究出最优组合，使其适应于当地局部地区的气候及土壤环境，治理水体污染。Phosphorus is the specific pollutant in eutrophication of water body and it is a major nutrient element of plants and microorganisms. Water eutrophication is not only the most common phenomenon, but also a difficult prob-lem in water pollution environment treatment at home and abroad. This paper, based on ecological restoration technol-ogy as the breakthrough point, studies some plants in saucer lake wetland, including Rumex acetosa L., Rorippa indica L., Hiern, Echinochloa crusgalli L., Beauv, Cyperus rotundus L., Daucus carota L., Phalaris arundinacea Linn, the six dominant plant biomass and the purification effect of phosphorus in the sewage, and also analyzes the relationship be-tween roots, biomass above ground and the effect of the sewage purification. According to the growth environment conditions of vegetation and vegetation of its own characteristics, our team explores the optimal combination which makes it adapt to the climate and soil environment of the local area to govern the water pollution.
