扎龙湿地水体富营养化与治理措施研究

Study on Eutrophication of Water Body and Control Measures in Zhalong Wetland

以扎龙湿地水环境为切入点，采用改进的灰色识别分析法对湖泊湿地以及沼泽湿地的水质进行分析。结果表明：湖泊湿地富营养化程度均为重营养状态，隶属重富营养状态的关联系数为0．003—0．602；东升水库处于重富营养状态，关联系数为0．150—0．724。通过分析扎龙湿地富营养化成因，提出了疏控淤泥、下层滞水带充氧、曝气，建立人工湿地以及生物工程相结合的治理措施。

This paper takes Zhalong Wetlands as the case study, analyzing the lake and swamp wetlands with the improved gray method of identification. The resuhs show that the lake and swamp wetlands and Dongsheng Reservoir are hyper - eutrophic, with the incidence coefficient 0. 003 -0. 602 and 0. 150 -0. 724. Based on the causes of eutrophication, it puts forward the fol- lowing measures：conveying and controlling for sludge, aeration in hypolimnion, and constructed wetlands combined with biological engineering.
