Research on Forest Utility for Maximizing Forest Value

Abstract

In order to measure forest carbon sequestration and make decisions on forest management, three models were established in this paper. Firstly, in Model I, we use ARIMA model and CBEF model to obtain the total biomass stored in the forest area and annual carbon sequestration of different dominant species in the same year. Then in Model II, the study classifies the value of forest ecosystem into carbon sink value, economic value and ecological benefit value. Then determine the weight of different forest values to obtain total forest value. Ultimately, In Model III, this paper defines the forms of economic benefits after tree harvesting based on economic principles, Tietenberg model and empirical equation, so as to obtain the optimal harvesting intensity and cycle of different tree species. So the optimal forest management plan can be determined. In this paper, the optimal management plan for forest value maximization in Palau within a certain period is given based on the above multidimensional measurement of forest value. Sensitivity analysis was also carried out, which shows there was little difference in the total value of forests calculated by the model when average log prices remained stable.
