“3S”技术(地理信息系统GIS,遥感技术RS和全球定位系统GPS)、网络技术、计算机技术等现代信息技术的迅速发展,极大地促进了资源经营、管理、利用的信息化、网络化、数量化和模型化进程,从而使“数字林业”的建设与发展成为可能。所谓数字林业是对林业静态、动态、分析决策等各种特征的统一的数字化表述与认识,它是以林业数字化数据为依托、用宽带网络连接各分布式数据库,以虚拟现实技术为特征,具有三维显示和无边无缝多级分辨率浏览的开放系统。林业的可持续发展要求林业内部各要素之间相互协调,如森林生长发育与其适生立地条件之间、森林培育与木
The rapid development of modern information technologies such as “3S” technology (geographic information system GIS, remote sensing RS and GPS), network technology, and computer technology has greatly promoted the informatization of resources management, management and utilization, and the network And quantify and model the process, thus making the construction and development of “digital forestry” possible. The so-called digital forestry is a unified digital representation and understanding of various characteristics of forestry, such as static, dynamic, analysis and decision-making. It is based on digital data of forestry, and is connected to distributed databases by broadband network. It is characterized by virtual reality technology and has Open system with 3D display and boundless seamless multistage resolution browsing. The sustainable development of forestry requires that all elements within the forestry should be coordinated with each other. For example, between the growth and development of the forest and its habitat, the forest cultivation and wood
