摘要: 以湖南省2004年森林资源二类清查数据为基础,用Visual Basic语言编辑程序,建立湖南省森林资源系统动力学模型,根据人工更新率R1、新造林面积率R2和开发建设项目占地率R3三个速率变量的变化,模拟7种方案,计算湖南省森林覆盖率和蓄积量从2006—2050年的动态变化过程。分析结果表明:以湖南省现实情况和湖南省“十一五”规划为依据确定的基本方案是湖南林业可持续发展的最佳政策方案。

关键词: 系统动力学, 森林覆盖率, 森林蓄积量, 湖南省

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
