Abstract

Abstract: On the basis of forest inventory data in 2004 in Hunan Province,we simulated the forest resources changes between 2006 and 2050 with the Visual Basic Code programming.The model simulated seven kinds of schemes based on three velocity variables including the artificial regeneration rate (R1),the new afforestated area rate (R2),and the project occupied area rate (R3).The result indicated that the basic scheme that takes Hunan Province’s realistic situation and the 11th 5-year plan of Hunan Province as the basis can reflect the rule of Hunan Province forest resources development.The basic scheme could be used for the optimal policy plan of sustainable forestry development in Hunan Province.

Key words: system dynamic, forest coverage, forest stock volume, Hunan Province
