Abstract

Abstract

Urban shallow landscape lakes suffered high eutrophication risk because of their special characters and functions in the water circulation system. Using a landscape lake located in Chengdu in Southern China, with a mixture of point source pollution and non-point source pollution, to which sustainable ecological maintenance was more difficult, we explored the methodology of AQUATOX to simulate and predict the state of this lake. According to the one-year monitoring data of water quality parameters, and trophic index was used to assess the eutrophication state to characterizing water pollution status. Using the measured data to fit the model results, we analyzed the sensitive parameters of the model operation, and determined the relevant parameters to increase the accuracy of the model in predicting the water ecological evolution of the water body. Using the height-fitting model to determine the effect of TP, TN and NH₃-N on the water quality of shallow water landscapes, and SWMM model to simulate the effect of LID measures on the reduction of rainwater pollution load in the lake. After LID measures, the stormwater runoff pollution load of total phosphorus and total nitrogen decreased by 59.34% and 58.39%, respectively, and the ammonia nitrogen load decreased by 21.94%. and the average reduction rates of TP, TN and NH₃-N in water were 38.57%,42.2% and 58.31%, respectively, which provided theoretical guidance for eutrophication and ecological restoration of landscape waters.
