Taking Cainiu Town, Tieling City, Liaoning Province as the main research area, the four evaluation index factors of water, fertilizer, gas and soil were selected through investigation and data collection. The method of combining fuzzy evaluation method and analytic hierarchy process is used to analyze the ecological aspects of comprehensive ecological links such as straw returning to grass, clear ridge returning to field, strip returning to field, deep rotation returning to field and strip returning to field. The final EBI index is obtained by multiplying the matrix by fuzzy analysis method, and then the EBI index and the grade corresponding to the score of the review are compared to get the final judgment result, and the comprehensive ecological benefit index is the final result. Obviously from the results, the comprehensive ecological benefits of soil and water conservation, carbon and oxygen fixation, and water bodies have improved significantly
