根据2013-03—2014-07的监测数据，采用综合营养状态指数法，对天津水上公园景观湖进行了富营养化评价。通过对氮、磷营养盐和叶绿素a含量，以及水体氮磷负荷的分析，结果表明：水景湖已经发生了富营养化，夏秋季较为严重；磷是水体富营养化的关键因子，氮、磷输入湖的负荷远高于输出负荷；底泥氮磷营养盐的释放以及水生植物治理氮磷措施不当是造成湖水富营养化的主要原因。
根據2013-03—2014-07的鑑測數據，採用綜閤營養狀態指數法，對天津水上公園景觀湖進行瞭富營養化評價。通過對氮、燐營養鹽和葉綠素a含量，以及水體氮燐負荷的分析，結果錶明：水景湖已經髮生瞭富營養化，夏鞦季較為嚴重；燐是水體富營養化的關鍵因子，氮、燐輸入湖的負荷遠高于輸齣負荷；底泥氮燐營養鹽的釋放以及水生植物治理氮燐措施不噹是造成湖水富營養化的主要原因。

Based on the monitoring data of Aquatic Park Landscape Lake from March, 2013 to July, 2014, the level and cause of eutrophication were analyzed by the comprehensive trophic level index (TLI) method. According to the analysis of the nitrogen, phosphorus, chlorophyll-a content, and nitrogen and phosphorus load, the results show that landscape lake was in high level of eutrophication, and it was more severe during summer and fall. Phosphorus was the key factor of eutrophica-tion. Nitrogen, phosphorus input load was much higher than the output load of the lake. Release of nitrogen and phosphorus from the sediments, and improper aquatic plant control countermeasure were the main cause of landscape lake eutrophica-tion.
