【 摘 要 】

The Yangtze River is the largest river in China. The quality of its water not only directly affects the safety of drinking water for residents, but also it is an important and far-reaching impact on China's ecological environment and economic development. Selecting the water quality monitoring data of the Yangtze River key section of China's ecological environment ministry with surface water environment quality standard in 2017. By the aid of matter-element theory analysis, the important sections of water quality of the Yangtze River are widely evaluated, and the evaluation results are compared with the fuzzy comprehensive evaluation method based on entropy weight, their comparison results are basically consistent. The study has shown that the matter-element analysis method can sort the water quality evaluation results for each monitoring section, and it more comprehensively analyses, discriminate, evaluates the object attribute level; the overall situation of water quality of the Yangtze is better, water quality grades are at grade II and above for most of the year.
