Non-wood Forest Assets Evaluation Technology Research

This paper systematically elaborated market comparison approach and income approach methods theory and some practical application in the assessment of non-wood forest assets. In the course of the study, on the one hand the Gray Correlation Analysis and the Hierarchical Analysis were introduced to make a comprehensive analysis to determine the relational degree and the weight of factors between the reference case and the non-wood forest assets in the application of the market comparison approach.On the other hand, it systematically analyzed the method that it could use the Regression Analysis to predict the yield of forest products in the income approach.Through the study on improved assessment approach of non-wood forest assets, it's not only conductive for the national macro to control the price of non-wood forest resources, but also for decision-making of non-wood forest management.The main conclusions are as following:1,This study makes a comprehensive and systematic study on theory and practice of the market comparison approach and the income approach in the application, introduced the gray correlation analysis, AHP in the market comparison approach and the regression analysis in the income approach in non-wood forest assets , systematically analyzed the theoretical basis, application conditions, methods steps of market comparison approach and income approach in non-wood forest assets .2,Using the gray correlation analyzed the relational degree of comparable case and objects in detail.There were many influencing factors of non-wood forest assets'price.If we selected different main factors of comparable case ,the influenced degree to objects would be different too. In this study, used the similar trends of various adjustment factors to measure the relational degree by the gray relational analysis method,and adjusted the key factors of comparable case,then determined the weights of comparable cases.Therefore it makes a valuable result that not only reflected the significant difference among the cases and also reflected the quality of various key factors in the same case .And it can get a more reasonable comprehensive assessment. 3,Determining the weight of comparable cases through AHP. Using it to determine the weight of reference case and objects, simplify and reasonable, it is applicable to both the quantitative indicators and qualitative indicators. It is superior for some situations in forestry survey that some data can not be collected, or it is a long cycle or the data is easy to lose.4,Used the regression analysis method to establish yield prediction model. Through the investigation of relevant information, by production output data and investigation method to establish production regression analysis prediction model, through the model calculation and analysis for the volume estimates. These for tea and tea value of scientific management and economic benefit analysis provides a detailed information on the production of tea, management and practical value.This paper using assessment theory and method of general non-wood forest asset for reference, combining with the particularity of the non-wood forest assets, probed into the market comparison approach and the income approach of the non-wood forest asset . Put forward our own views for several problems about the assessment of non-wood forest asset that to be solved as soon as possible. These to further improve asset appraisal method has some reference value.
