　　5.Data analysis and interpretation
　　In this study, quantitative analysis will be used with the aim of determining the spatial and temporal distribution levels of contaminants within the water. The Némero (Nmeoerw) mean method was used to calculate the calculated concentrations, with the expression:

　　(5-1)

　　Equation (5-1) in cmax 、c 、c respectively, that the maximum concentration of pollutants monitored (mg/L), the average concentration (mg/L) and the average value of Nemero (mg/L).
　　When calculating the indicators of each water body in Qujiang Pool using the Nemero average formula (Equation 5-1), Qujiang Pool is divided into four parts: the slow-flowing area, which is denoted as P1: including points 1 and 2; the inlet area, which is denoted as P2: including points 3 to 6; the outlet area, which is denoted as P3: including points 7 to 9; and the connection area with Furong Lake, which is denoted as P4: including points 10 and 11.
　　The article mainly introduces the geographical location, natural features and hydrological conditions of Qujiang Pool. The spatial and temporal distribution and analysis of the measured values of six indicators, including CODMn、TP、TN、NH3-N、NO3-N and NO2-N, were carried out by the Nemerov mean method (Nmeoerw), and the treatment planning of Qujiang Pool was carried out based on the analysis results combined with urban water quality standards.
