Abstract: In order to accurately evaluate the ecological carrying capacity of vegetation landscape in nature reserves, and improve the accuracy and efficiency of evaluation, a method for evaluating the ecological carrying capacity of vegetation landscape in nature reserves based on improved analytic hierarchy process is proposed. Principles for evaluating the ecological carrying capacity of vegetation landscape are identified based on the Delphi method. Primary and secondary indicators are selected to construct an evaluation index system for the ecological carrying capacity of vegetation landscape in nature reserves. Due to the insufficient ability of traditional methods to handle fuzzy information, fuzzy theory is adopted to improve the traditional analytic hierarchy process, determine weights, and combine fuzzy comprehensive evaluation factors to comprehensively evaluate the ecological carrying capacity of vegetation landscape in nature reserves. The experimental results show that the evaluation weight calculation accuracy of the proposed method reaches 99%, and the time taken is less than 8.35 seconds.

Keywords: analytic hierarchy process; AHP; nature reserves; vegetation landscape; ecological carrying capacity.
