| Abstract: | With the principal component analysis we seek out the main factors which affect the water quality of Beijing-Hangzhou Grand Canal in Huaian, obtain factor score function, calculate factor score of each factor and water quality total score. According to the above results we perform water quality evaluation of Beijing-Hangzhou Grand Canal in Huaian. |
