| 摘 要： | 以数字西江水质预警预报系统为研究背景，对西江干道进行了数字化、河道贴体网格生成，以GIS数据为基础,进行一维恒定流方程组和二维水质模型计算，并且实现浓度场在GIS平台上的可视化。这种基于GIS的二维水质模型网格计算为水质的时空模拟和预测提供了一条新的途径；同时，也可以为水环境保护者在管理和决策时提供有利的支持。

| Abstract: | Taking digital warning and forecasting system of water quality in Xijiang River as background, the authors digitize the watercourse of the river, develop the close-fitting grids, and then calculate the numerical equations of one-dimensional steady flow and two-dimensional water quality model based on GIS. The results of the concentration field are implemented on the platform of GIS. The two-dimensional water quality grid calculation based on GIS supplies a new way of spatial and time simulation and forecasting of water-quality, and can also provide favorable support to the management and decision-making for water environment researchers. |
