Research on the construction of ecological mechanism and sustainable development of university English teaching based on multi-objective planning

This paper firstly addresses the construction of the university English teaching ecosystem and gives the basic structure of the university English teaching ecological mechanism. Secondly, the multi-objective planning model is used to analyze the influencing factors of the university English teaching ecological mechanism, and the index evaluation system of the university English teaching ecological mechanism is constructed. Finally, to verify the effectiveness of the university English teaching ecological mechanism, the entropy weighting method was used to determine the index weights. The results show that the evaluation ratio of the first-level indicators with a C grade or above is 89.61%, and the weight values of the top three second-level indicators are 0.865, 0.808, and 0.715, respectively. It shows that multi-objective planning can effectively analyze the influencing factors of the ecological mechanism of English teaching and then promote the sustainable development of English teaching.
