近日,园艺与植物保护学院罗云建副教授在《Earth System Science Data》发表题为《A review of biomass equations for China's tree species》的综述论文。论文全面系统地总结了我国1978年至2013年林木生物量模型的研究成果,首次构建了我国林木生物量模型标准库,对于区域森林碳收支核算及林学基础研究具有重要科学价值。
Google Earth在森林防火信息管理中的实现方法
Google Earth 森林防火信息管理 实现方法
2011/8/26
为了提高森林防火信息管理中空间数据的利用效率,针对Google Earth的共享遥感影像数据,提出利用Google Earth的二次开发,将其应用到森林防火信息管理。笔者通过调用Google Earth类库的方法,开发实现了森林防火信息系统。系统读取Access数据库的坐标信息,自动生成并加载各类地标文件,实现防火专题信息定位、GPS跟踪、历史火场位置重现等功能,为森林防火管理与决策提供依据。
