在分析现有森林资源更新研究成果的基础上,从生产实践的角度提出基于二类调查小班数据的森林资源更新技术路线和方法。该技术方法以前期二类调查数据、年度森林经营档案数据及两期卫星影像作为数据源,应用3S、数学模型、数据库等技术方法结合现地调查核实,实现落实到小班的森林资源更新及年度出数。实践表明,该技术方法高效、可行,更新成果数据详实、可靠。

Based on the analysis of research result concerning forest resource regeneration,An approach and technology route for updating forest resource data based on the information contained in forest sub-compartment of forest management inventory was proposed from the production practice point of view.The technical route implements updating the annual statement of forest resources and data updating in sub-compartment level based on the data of previous forest management inventory,annual forest management archive data and two-stage satellite image,by applying 3S technology,mathematical model and database technology,combined with field investigation.The practice shows that the approach is feasible and supports the full and accurate data updating efficiently and reliably.
