摘　　要：该文基于县级森林防火的需求,从森林防火指挥需要出发,以森林资源多源数据(遥感图像、GPS数据、地形图、DEM数据、地面调查数据和防火资源数据等)为基础,充分考虑森林资源空间性、多元性、多态性的特点,解决了森林防火本底数据中属性数据和空间数据一体化管理问题,实现了将RS、GPS、GIS和3D4种技术有机结合的森林防火指挥的管理模式。对森林防火系统的技术构架进行了分析,对系统设计中的若干关键技术问题进行分析并提出了解决方案;以MapX、OpenGL、VC为开发工具,设计并开发了一个县级森林防火系统。Based on the demand of forest fire prevention at county level, and embarked from the demand of forest fire prevention direction, this paper fully considers the features of spatiality, pluralism, and polymorphism of forest resources on the basis of forest resource multi-souree data （RS image, GPS data, topographical map, DEM data, ground survey data and forest fire prevention resource data, etc. ）, then resolves the issue of integration management of the attribute data and the spatial data in the background data of the forest fire prevention, thus brings forward a management pattern of forest fire prevention direction which effectively integrates the RS, GPS, GIS and 3D technology. The paper analyses both the technical framework of forest fire prevention system and some key technical problems of the system, and then puts forward the resolution of these problems. In addition, the paper designs and develops a forest fire prevention system at county level using the tools of MAPX, OPENGL and VC.
