Abstract

Abstract:

During the short term of 2018 and 2019, Xiamen University undergraduates' social practice team called "Trace of the Green Line" went to Chongqing, Shanghai and other major cities along Yangtze River to do some social practice activities. We collected the local water samples and determined the content of phosphate and permanganate index in water samples. At the same time, we had the promotion and the network questionnaire survey to promote the consciousness of protecting water resources.

Key words: Water quality of Yangtze River, Water quality analysis, Social practice
