Analysis on influential factors of water quality in key sections of Yangtze River basin in China

摘要

The Yangtze River Valley is the largest of China’s seven major water systems,the longest water system,and the length of 6300 kilometers,and ranked third in the world.Its water quality is not only closely related to the residents’drinking water safety,but also to the ecological environment of China has an important impact.Based on the panel data and stochastic forest modeling of the key sectional water quality monitoring data of the Yangtze River basin since 2018,NH3-N(ammonia nitrogen content)has the most important effect on water quality,and its value directly determines the quality of the water quality.
