Abstract
To understand the impact to the water quality of Huangpu River, a serious scientific research has been conducted. Using the questionnaire answered by the residence and samples of the water collected across different locations, a model has been setup to analyse the relationship between the water quality and residents’ knowledge of environmental protection. A novel Grey Relational Analysis method was proposed to calculate the impact factors from year 2013 to year 2018. The analysis results show that the residents’ environmental awareness and their cognition of water quality is opposite to the actual water quality because of the level of education level of the residence around the river. As for the orientation of the government’s environmental protection measures, the research displays a new focus from the perspective of social science: ways to popularize the status quo of environment protection to the general public.
