Evaluation of Ecological Tourism Land Use Benefit based on the Coupling Relationship

Using coupling relationship model between green economic development theory and the land use benefit system, combined with mathematical modeling, this paper designs the global coupling degree algorithm, and represent the coupling efficiency of land use. By using MATLAB Simulink, it fits the curve in the coupling process, and the coupling curve of ecological tourism land use social efficiency and the ecology benefit is obtained. Through the analysis of the coupling result, the coupling model can effectively calculate the coupling degree of ecological benefits and social benefits, which provides a theoretical basis for the research on the evaluation of land use efficiency.
