依据贵州省林业调查规划院 1979、 1984、 1990、 1995、 2 0 0 0年 5次森林资源连续清查资料 ,从森林资源面积、蓄积量、组成结构等方面总结了该省近 2 0年间森林资源动态变化的详细资料 ,并对变化的原因进行了分析。结果表明 ,2 0世纪 70年代末至 80年代末 ,林业用地面积、天然林面积与蓄积量均呈下降趋势 ;其后 ,由于贵州省政府及林业部门的高度重视 ,实施一系列林业生态保护与可持续发展工程 ,如国家“长江防护林工程”、“珠江防护林工程”等 ,贵州森林资源自 1990年以来持续稳定增长 ,促进了生态环境改善 According to the continuous inventory data of forest resources in 1979, 1984, 1990, 1995 and 2000 in Guizhou Province, this paper summarized the forest resources in recent 20 years in terms of forest resource area, stock volume and composition structure, Dynamic details of the changes, and the reasons for the changes were analyzed. The results showed that from the late 1970s to the late 1980s, forestry land area, natural forest area and stock volume all showed a decreasing trend. Since then, due to the great attention of Guizhou provincial government and forestry departments, a series of forestry ecological protection and For sustainable development projects such as the state “Yangtze River Protection Forest Project” and “Pearl River Protection Forest Project,” Guizhou’s forest resources have enjoyed sustained and steady growth since 1990, contributing to the improvement of the ecological environment
