Investigation and Analysis on Eutrophication of Urban Landscape Water Body in Mianyang City

In the construction of modern urban green space,landscape water has been paid more and more attention.However,the urban landscape water bodies are closed and are slow-flowing water bodies with static or poor fluidity,it is easy to cause eutrophication and lose the original landscape value.In this paper,the water quality of five water bodies in parks and residential areas in Mianyang city was determined.The eutrophication status of urban landscape water bodies was analyzed. The research results show that the water quality of urban landscape water bodies is poor, all of which are Grade V water quality.There are differences in the degree of eutrophication among different types of water bodies, and the degree of eutrophication in residential areas is higher than that in parks.Among them, the landscape water bodies in residential areas are moderately eutrophication, and the park landscape water bodies are mildly eutrophication. The research results provide basic data and useful references for the treatment of water quality of urban landscape water bodies and the prevention of eutrophication in Mianyang City.
