Eutrophication Characteristics and Analysis of Environmental Factors for Urban Landscape Water in Southwest China
To understand the eutrophication characteristics and key environmental factors of urban landscape water in Southwest China,this paper selected a total of 18 landscape water bodies in Chongqing City(8 mountain cities with deep-water enclosed/semi-enclosed water)and Chengdu City(10 plain shallow water bodies)as the research objects,and monitored their water quality during the algal prone season.The results showed that the TLI(Σ)of urban landscape water bodies were between 48.09%and 70.72%.Overall,it presented mild and moderate eutrophication,accounting for 67%and 22%respectively.Correlation analysis showed the main influencing factors for eutrophication of deep-water enclosed/semi-enclosed landscape water bodies in Chongqing's mountainous areas and eutrophication of shallow water landscape water bodies in Chengdu Plain are TN,chlorophyll-a,SD,DO,chromaticity,water temperature,and conductivity.
