2、2.Study design

　　The type of study is defined as routine monitoring, which will involve field sampling procedures and equipment, sample transportation and preservation, and samples will be returned to the laboratory for testing and analysis of water quality indicators to assess the long-term trends of key indicators in key water bodies, and then the resulting data will be analyzed to determine the spatial and temporal distribution levels of pollutants in the water body using quantitative analysis to provide data references for relevant researchers.

　　The specific research contents are as follows:
　　1.To investigate and analyze the current situation of pollution of urban landscape water bodies in China, and to clarify their characteristics and main sources of pollution;
　　2.Investigate and study the basic conditions of the geographic, natural and hydrological conditions of Qujiang Pool, and carry out continuous monitoring of the water quality of Qujiang Pool.
　　Continuous monitoring of the water quality of Qujiang Pool;
　　3.The measured water quality of the Qujiang Pool of the individual indicators of time and space distribution analysis;
　　4.Establish water quality evaluation model, use single factor evaluation method (standard index evaluation method) and fuzzy comprehensive evaluation method to evaluate the current situation of water quality of Qujiang Pool, and to compare the two evaluation methods.

　　According to the characteristics of the water environment of Qujiang Pool, 11 representative observation points were taken in the slow-flowing area, inlet area, outlet area, and the connection point with Furong Lake (Fig 2.1), which were recorded as point 1, point 2 to point 11. The monitoring work will be determined from April 8, 2023 to April 29, 2023, and the frequency will be once a week.
