Along with the development of social economy, the expansion of city scale andthe increase of people’s demand for living standard and environment, more and moreartificial scenic water appeared in city. The artificial scenic water not only beautifyurban environment but also could improve the micro climate surrounding the water.However, water quality’s variation of the artificial landscape water brings new waterenvironment problem. In this paper, the landscape water system of QuJiangChinational park and Datang hibiscus garden was the study object, several related workswere carried out, such as water quality monitoring, water monitoring and water qualitysimulation.The main content of this paper are as follows:(1)Monitored sampling continuously and analysed the water quality ofQuJiangChi national park and Datang hibiscus garden. The monitoring results show thatthe water quality of the entire lake system mainly meets the quality standards of thelandscape recreational water. But the phenomenon of eutrophication is serious, theaverage contents of total nitrogen and total phosphorus in water system were greaterthan the international standard. According to the monitoring datum of each samplingpoints, the quality of water was evaluated by using fuzzy comprehensive evaluationmethod and single-factor evaluation. The evaluation results of fuzzy comprehensiveevaluation method indicated that: the water quality of QuJiangChi is Ⅰ class, thewater quality of hibiscus garden is Ⅱ class. The results of using single-factorevaluation are both Ⅴ class.(2)According to the situation of QuJiangChi landscape drainage, drainage water volume was monitored and recorded for long-term. And based on the record, waterquantity balance was established to calculate the leakage and analysis the cause of thelake water leakage.(3)The water quality model software of WASP simulated the water quality ofQuJiangChi park, which is relatively commonly used in water quality simulation.Though the simulation results, the curves of measured and simulated matched well. Butthe values of measured and simulated still existed a certain deviation. So it needed us tostrengthen the related work in the future.(4)This paper presents methods of controlling water quality based on watersystem landscape situation of the park. For example: strengthening the management ofpark, controlling of storm flow pollution and enhancing the lakes self-purification.
