Tree assets evaluation of natural uneven-aged stand by selective cutting income method
摘要
Abstract
Taking uneven-aged stand of Pinus massoniana as the research object, the paper expounded the basic principle of selective cutting income method for tree assets in different age forests. As the key technical bottlenecks of selective cutting income method,the paper used dummy variable method to establish a storage growth rate model with the site quality grade as dummy variable,the volume and interval as the instrumental variable,and used 204 pieces fixed plots of multiple observation data and the ant colony algorithm to solve the model parameters. The applicability test was carried out through 32 pieces plots which showed that the absolute relative error of the model was 8.08% and the average system error was 2.17%. Based on the model combining with selective cutting income method,the paper discussed assets evaluation technology of the uneven-aged stand of P. massoniana forest, analyzed the effects of different cutting intensity and the interest rate of on the assets valuation, pointed out the selective cutting intensity of natural P. massoniana was more reasonable between 30%-40%,and the key technical points and possible problems that should be paid attention to,in order to provide references for improving the technology of uneven-aged stand assets evaluation.关键词
