摘要
河流泥沙淤积是许多大江大河洪水泛滥的重要原因之一 ,关于泥沙淤积过程已经建立了大量数学模拟模型系统 ,这些系统具有强大的模拟计算能力 ,但其时空过程数据表现和进一步空间分析能力很弱 ,现有 GIS系统具有很强的时空过程数据可视化表示和空间数据分析能力 ,通过与GIS集成 ,可望解决这个问题 ,本文研究并实现了一个基于 GIS与数学模型集成的泥沙过程可视化分析系统。
WT5BZ]:Sedimentation is one important cause of river flooding. Many mathematical simulation model systems for this process have been successfully established. These model systems are very powerful in simulating calculation, but much more weaker in visualization of process data and further spatial analysis. Current GISs are very strong in visualization and spatial analysis. So by integrating with GIS, it is hopeful to resolve this problem.In this paper, a visualized analysing system of sedimentation process is studied and implemented.
