摘　　要：利用再生水补充景观水体已经成为水资源再生利用的重要途径,但该类景观水体的水质保持情况尚缺乏长期跟踪研究。选择已经运行多年的泰达再生水景观河道进行研究,水质监测结果表明,河道型湿地对再生水中的TN和TP具有较好的净化效果,但河道水体亦存在富营养化趋势。依据综合营养状态指数(TLI)可知,泰达再生水景观河道水体总体为轻-中度富营养化;藻类定性分析结果表明,该再生水景观河道水体富营养化类型为绿藻-硅藻-裸藻型。Use of reclaimed wastewater as make-up water of landscape water bodies has become an important way of water reclamation and reuse. However, there is still a lack of long-period studies on quality conservation of landscape water bodies using reclaimed wastewater. The TEDA scenic watercourse using reclaimed wastewater for several years was chosen as a case study. Monitoring data showed that this scenic watercourse was effective in purifying TN and TP in reclaimed wastewater. However, according to the trophic level index and indicator algae, the total trophic state of TEDA scenic watercourse was in slight-middle eutrophic state. The qualitative analysis of algae demonstrated that the dominant species were Chlorophyta, Bacillariophyta and Euglenophyta.
