摘要: 以森林经理学为理论基础,以地理信息系统作为系统管理平台,以三明市森林资源调查数据、数字地图为信息来源,借助相关数学分析方法,对森林资源1996—2005年期间的动态规律进行研究。结果表明:三明市林业用地面积基本保持稳中有升格局;森林覆盖率虽有起伏,但基本稳定在76.8%的较高水平上;人工林的面积呈增长趋势;天然林面积逐年减少;活立木蓄积量1996年后呈持续上升趋势。该项目研究为制定三明市林业的可持续发展方针提供科学决策依据,对于进一步促使森林资源管理信息化有一定的技术基础和应用价值。

Abstract: With the help of the relevant mathematical analysis approach,an investigation of dynamics of the forest resources based on the theoretical foundation of forest management was conducted withGIS used as a platform of system management. Its information sources come from data and digitalmaps of forest resources of Sanming City from 1996 to 2005. The result indicats that:the area of forest land of Sanming City has increased steadily. Althoughforest coverage rose and fell,it generally remained at a level of 76.8%. Thearea of the planted forests has increased,while the area of nature forests decreased year after year. The growing stock of standing timber has had a trend of increase since 1996. This study provids a scientific basis for drawing up policiesof sustainable development of forestry of Sanming City and a technologicalbasis as well and will be of a great value for promoting informationization ofthe management of forest resources.
