| Abstract:【Objective】To study the characteristics of water quality and pollution in the Xiaoqing River Estuary, and to provide scientific basis for water environment management in the Estuary.【Method】The water quality of the Xiaoqing River from Shicun to Yangjiaogou was selected as the study river section, the water quality evaluation was conducted based on the water quality monitoring data of 4 water quality sampling sections from 2019 to 2021. The main pollutants of each section were analyzed by the principal component analysis method, and the sources of the main pollutants were discussed with the industrial and agricultural layout of the study area.【Results】The evaluation results show that the water quality of each section of the Xiaoqing River Estuary has been improved from 2019 to 2021, and the water quality level of each section has been reduced to Class IV in 2021; the common pollutant exceeding the standard at each section is total nitrogen(TN), of which nitrate(NO3-) is the main pollutant form, the NO3- at Shicun is affected by the mixed action of non-point and domestic sewage pollution, and the main source of NO3- at Houxinzhuang is sewage and manure pollution; The meteorological elements such as temperature and rainfall also indirectly affect the water quality in the Xiaoqing River Estuary.【Conclusion】The comprehensive water quality identification index combined with combinatorial integration method is suitable for the water quality assessment of the Xiaoqing River Estuary; the main pollutant of the Estuary is TN, which should be paid attention to. |
