摘要
在河势贴体二维正交网格生成方法的基础上,采用边界拟合坐标系方法,将正交网格既与河势拟合又与河道边界线拟合,研究基于MapObjects的二维正交曲线网格生成技术;利用Visual Basic工具开发了二维正交曲线网格自动生成系统,实现了二维河流自动网格化;结合二维水质模型和GIS叠加功能,探讨了二维正交曲线网格在水质模拟中的应用。
The generating technology of two-dimension orthogonal curve grid based on MapObjects was researched with the methodof river-regime and boundary fitted coordination system.And the autogeneration system of orthogonal curve grid was programmed with Visual Basic.The orthogonal curve grids of two-dimension river fitting to its boundaries were automatically generated.At last,its application of two-dimension water quality model to water quality simulation using the overlap of GIS was discussed.The forecast and prevention ability of water environment pollution accident is increased greatly.
