摘要
利用计算机技术及可视化技术构建草原干旱识别可视化系统,在草原地区抗旱减灾工作中具有重要的作用。应用标准化降水蒸散指数(SPEI)对草原干旱进行识别,采用Visual Studio 2010和Arc GIS Engine 10.2结合C#语言和GIS技术,研发出草原干旱识别可视化系统。以松嫩草原为实证研究区,系统实现了GIS浏览与灾情管理、草原干旱识别空间化和干旱识别结果可视化等功能。该系统的构建可为草原地区干旱灾害监测提供技术支持,为区域干旱灾害管理提供科学参考。
The visualization system of grassland drought identification was developed based on computer technology and visualization technology. The system plays an important role in drought resisting in grassland area. In this paper,the standardized precipitation-evapotranspiration index was used to identify grassland drought. By using of the Visual Studio 2010 and Arc GIS Engine 10. 2 software coupled with C# language programming and GIS technology,the visualization system of grassland drought identification was constructed. The Songnen Grassland in northern China was taken as study area,and the visualization system was utilized to GIS browse and disaster management,spatialization and visualization of the result of grassland drought identification. This system can be used as technology support for monitoring grassland drought and scientific reference for the management of grassland drought disaster.
