利用人工湿地与景观河道相结合构建水体循环系统，保持和改善城市景观水体水质，防止水体发生富营养化。由利贝格最小值定律，确定水体中TP对于水体富营养化发生过程的重要作用，将TP作为控制水体发生富营养化的首要约束。循环系统经过一段时间运行后，监测景观河道中的TP含量，结果表明TP含量逐渐趋于稳定。以循环系统内存在的局部死水区域作为对照区，比较景观河道和死水区的水体水质，结果显示在6次取样中景观河道中的TP ，氨氮的含量大部分低于死水区的含量。通过TP含量测定和分析，充分说明构建的循环系统在景观水体水质保持和改善中发挥了有效的作用。

In this article,man-made wetland and landscape rivers were used to build the water circulation sys-tem to maintain and improve the quality water of urban landscape and to prevent eutrophication. According to the liebig law of the minimum,the TP played an important role in the process of eutrophication and was the primary constraint condition to control eutrophication. After the circulation system operated,the TP content of the landscape river was determined and the result showed that the TP content became stable. Compared the wa-ter quality of landscape river with stagnant water, through the 6 times samplings, the content of TP and ammonia nitrogen in the landscape river was lower than the stagnant water. Through the analysis of the TP con-tent,the role of the water circulation system was proved.
