摘　　要：[目的]研究天津滨海地区景观水体富营养化的特征及成因.[方法]根据2013年3～9月天津滨海地区典型景观水体——清净湖富营养化监测数据,采用综合营养状态指数法,对清净湖景观水体的营养状态及其成因进行评价与分析.[结果]清净湖景观水体属中-重度富营养化水平,综合营养状态指数随季节变化十分明显,呈春季低、夏秋季高,尤其是7、8月较为严重,为重度富营养状态;富营养化成因分析表明,雨水、再生水补水携带的污染物聚积及高氮磷底泥释放是清净湖景观水体富营养化加剧的主要原因.[结论]该研究为天津滨海地区景观水体富营养化防治提供理论依据.[ Objective ] The research aimed to study the eutrophication characteristic and cause of landscape water body in coastal area of Tianjin. [ Method] Based on the eutrophication monitoring data of Qingjing Landscape Lake in coastal area of Tianjin from March to Scptember in 2013, the eutrophication level and cause of Qingjing Landscape Lake were analyzed by the comprehensive trophic level index （TLI） method. [ Result] The eutrophication level of Qingjing Landscape Lake was moderate - severe eutrophication, and the TLI changes with the seasons was very obvious,the TLI values was low in spring,and high in summer and autumn. In especial Qingjing Landscape Lake were at severe eutrophication level in July and August. The primary causes of serious eutrophication were nutrients accumulation from rainwater runoff, reuse water and sediment. [ Conclusion] The study provides the theoretical basis for prevention and cure of eutrophication in coastal area of Tianjin.
