摘要: 为了推动草原信息化管理的进一步发展,本研究基于现代化信息技术,主要运用3D-GIS技术、遥感技术、仿真技术等相关技术,以具有典型草原代表性的锡林郭勒盟为示范区,建立了虚拟草原三维数字模型。该研究首先依据草地生态学原理,对草原生态系统信息数据(基础图件及属性数据)进行筛选;然后对筛选后的空间数据进行叠加并建立其与属性数据的关联;最后将草原生态信息镶嵌于三维数字模型之中,实现了在草原三维数字模型中进行草原生态信息查询分析功能。结果表明,运用C/C++语言调用OpenGL图形库从底层开发的草原三维数字模型快捷稳定,渲染速度快,可方便地动态查询示范区草原地理信息,为进一步地研究三维虚拟草原提供技术支持。

Abstract: To promote the further development of information-based management of grasslands, this work established a grassland three-dimensional digital model based on modern information technology, including 3D-GIS technology, remote sensing technology, simulation technology and other related technologies. The foundation of the 3D-digital model is based upon the Xilin Gol grassland as a demonstration area. The establishment of this digital model is based first on screen grassland information data (maps data and attribute data) according to the principles of grassland ecology; second, an overlay of the layer data filtered to establish the association with attribute data. Finally, the grassland information data was embedded in the three-dimensional virtual space model, to realize queries and analysis of grassland information. The research showed that the grassland three-dimensional digital model developed using the C/C++ language to call OpenGL graphics library works fast and steadily with fast rendering speed, and can provide real-time and dynamic queries of grassland information, and supply technical support for further studies on three-dimensional virtual grassland.
