An environmental pollution assessment method for tourist attractions in nature reserves based on factor analysis

In order to improve the accuracy of environmental pollution assessment and shorten the assessment time, a factor analysis based environmental pollution assessment method for tourist attractions in nature reserves is proposed. Firstly, establish an environmental pollution assessment index system for tourist attractions. Secondly, based on the evaluation index system, collect relevant data on environmental pollution in tourist attractions, including air pollution data, water pollution data, soil pollution data, noise pollution data, ecosystem data, and socio-economic data. Finally, a standardised matrix was constructed using factor analysis to extract common factor variables of environmental pollution risk in tourist attractions. Calculate the comprehensive factor score of environmental pollution risk and complete the environmental pollution assessment of tourist attractions. The experimental results show that the environmental pollution assessment results of this method are completely consistent with the actual results, and have a shorter assessment time.
