摘　　要：为了解西南地区城市景观水体富营养特征及关键环境因子,选取重庆(8个山城深水型封闭/半封闭水体)和成都(10个平原浅水型水体)共18个景观水体作为研究对象,在藻类易发季节对其进行水质监测。结果表明,西南地区城市景观水TLI(Σ)处于48.09~70.72之间,整体上呈现轻度和中度富营养化,分别占67%和22%。经分析发现,重庆山城深水型封闭/半封闭景观水体及成都平原浅水型景观水体富营养化主要影响因子为TN,Chl-a,SD,DO,色度、水温和电导率。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 deepwater 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.
