Based on the definition of green development and the characteristics of the Tuojiang River Basin, nine primary indicators and 17 secondary indicators are selected to establish a green development evaluation system for the Tuojiang River Basin from the four aspects of “economy, society, resource and nature”, and the weights of each indicator are determined by entropy method, with Zigong, Luzhou, Deyang, Neijiang and Ziyang as the research objects. The grey correlation method is used to analyze the 2017 statistical data to evaluate the green development of the Tuojiang River Basin and put forward some suggestions.
