Study On The Evaluation Technology Of Tea Resource Assets

This paper, staring from the problems existing in the tea garden resource assets assessment, according to the theory of forest resource assets appraisal, combing with characteristics of the tea plantation resources assets, analyzes the application of the analysis hierarchy process(AHP)、the gray relational analysis、TOPSIS in the market value method, and introduces the regression analysis in the application of income approach. So as to obtain the tea resource assets evaluation of new methods and new technologies, to improve its theory and method system, and to enhance the work efficiency and the accuracy of the result, as well as provide a reliable guarantee for the development of tea industry. According to the research this article adopt AHP and the gray relational comparison with better effect in combination with market value method、the regression analysis、the income approach to assess the tea garden resource assets. In the meanwhile, the author illustrates the concrete application of those methods based on the result of the research and relevant living examples. On the one hand, this paper gives its own ideas and improvements about the weight of each comparable cases on the basis of fundamental of the market comparison method. On the other hand, the author sets up a reasonable and scientific model for the yield prediction of tea garden. The model can accurately predict the output of tea garden in the specific period. Through the study of the tea garden resource assets assessment an d the application of specific methods, the mainly conclusions are as follows:1、As one of the commonly used method on the tea resource valuation methods, the market comparison method has a strong fuzziness and want many factors which can influence the assessed value. This article introduces AHP、gray correlation analysis、TOPSIS in the market comparison method and effectively analyzes some concrete cases by the use of reasonable AHP in addition to reasonable gray relational analysis. The emphasis is market comparison method as well as its application in the practice, and the comprehensively analysis of theory foundation、condition and step of market comparison method in the evaluation work.2、Using the theory of gray relation analysis to appraise correlation of each reference case and estimated case, it has certain limitations if you directly apply correlation on a tea garden resource assets evaluation, so we make three hypotheses on the correlation analysis.Firstly, the influencing factors of reference and object is equal and vital. Secondly, all factors on the tea garden resource assets value is irrelevant to time that is the coordinates horizontal time axis into influencing factors related to the axis, instead of using the time to arrange. Thirdly, the sequence of each element represent certain factors, process and quantify, and then analyze degree of association. The gray relation analysis can make up the defects brought by the systematic analysis of mathematic statistics, the number of sample and the regularity of reference case just make slight difference. It is accurate and small calculation workload, so it is very convenient and has a extensive application prospect and high value in the tea garden resource assets evaluation.3、The weight of each reference case can be calculated by the gray relational analysis directly, or by AHP method to confirm, two methods have mainly same result.4、AHP is a kind of multi-objective decision method, which combines analysis with qualitative analysis. It is used in the determining relative to the reference case for the weight of assessment case, and is applicable to the qualitative indexes and quantitative indexes due to its simpleness and rationality. More importantly, it has a lot of advantages for those situation which has a long cycle to survey data sampling or which tend to lose data.5、After build the prediction model using the regression analysis, we can predict the yearly output of tea garden by providing the stand age of tea garden. As a result, it provides the convenience for the tea economic benefit analysis management and a more detail and reasonable data evaluation for tea plantation resource assets. That has great practical significant for the management of tea garden and the asset operation in the same area etc.
