The Research On The Evaluation Of Ancient And Famous Trees

Based on the basic methods and principles of forest resource asset evaluation,this paper introduces AHP and GRA,and combines the characteristic of ancient and famous trees,the basic principles,the application conditions and the concrete method steps of the cost method,the income method and the market method in the evaluation of the value of the ancient and famous trees is elaborated,and finally the practical application of ancient trees and famous trees is discussed and compared.Based on the particularity of ancient and famous trees,three kinds of evaluation schemes are used to evaluate and compare the monetary value of ancient and famous trees.First of all,according to the composition of the value of ancient and famous trees,screening the impact of the value of ancient and famous trees 11 evaluation index factors,according to the quantitative classification to determine the adjustment coefficient score table,on this basis,respectively the income method and cost method is used to evaluated.In the application of market method,introducing analytic hierarchy process and gray relational analysis method to determine the reference case for the assessment of the weight,and further enriched the forest resource assets assessment technology in the ancient and famous trees.The application of the evaluation of the value of ancient and famous trees has improved the efficiency and flexibility of the assessment work,and provided the theoretical basis for the evaluation and protection of ancient and famous trees.This paper provides a theoretical basis and reference for the future research on the evaluation methods of the value of ancient and famous trees.The results of this study are as follows:(1)This paper systematically studies the prerequisites and method steps of the cost method,the income method and the market method in the evaluation of the value of the ancient and famous trees,so the evaluation method and the evaluation index factor is cognized,and according to the characteristics of the value of ancient and famous trees,determining the value of adjustment coefficient of ancient and famous trees,revising value of the assessment,making assessment of the ancient and famous trees of the monetary value more comprehensive and reasonable.(2)In the application of cost method for evaluating the value of ancient and famous trees,the comprehensive consideration to determine the maintenance and management costs of ancient and famous trees,and its equivalent to the present value of the cumulative sum,with referencing to the adjustment coefficient score table,determining the coefficient score of the evaluation index,and then calculating the revised assessment value,obtaining the final assessment results of ancient and famous trees.(3)The using of income method to assess the value of ancient and famous trees,by reference to the garden nursery price data,building a statistical model to estimate the future assessment of ancient and famous trees,using the relevant adjustment coefficient to evaluate the value of ancient and famous trees.(4)On the basis of understand the characteristics of ancient and famous trees using market method to estimate the value of ancient and famous trees.Concerning about the market method,introducing gray relational analysis and analytic hierarchy process,it is has great significance for the evaluation of ancient and famous trees.
