摘要
本文从数字地球、数字林业概念出发,提出“数字林场”建设技术体系,并总结出以林场或县级林业局为管理单位的数字化林场建设的“8533”技术框架及技术路线,即选择八种林场基础数据获取方式,实现五种林图的绘制、更新,运用三类模型为林业生产经营及决策提供参考依据,建立林场小班影像、空间、属性三个数据库。最后分析并总结了数字林场在森林资源信息管理、森林防火、森林立地分析评价等方面的作用和效果。
The authors propose the concept of digital forest farm and describe its construction based on digital earth and digital forestryThe digital forest farm is constructed based on the forest farm or the forestry bureau at county level.We describe 8 methods to get the forest farm data and 5 mtehods for forest images designing,drawing and upgrading.We use 3 models to offer the reference for the forestry production,management and decision support.Moreover,we set up the image,space and attributes database of subcompartment.Finally,we analyze and summarize the functions and effects of the digital forest farm in the resource information management,forest fire-prevention and forest site analysis and evaluation.
