摘要
以栅格DEM为基础,以地理信息系统为平台,自动提取模型计算所需要的参数,基于COMGIS的ESRI ArcObjects平台,应用VBA进行二次开发,实现了水文模型和产沙模型以及模型与GIS的紧密耦合,最终实现了模型分布式功能。
Based on the grid DEM,the necessary parameters for the numerical model were extracted automatically from the GIS database.The runoff and sediment yield model was re-developed by the VBA and the ESRI ArcObjects of COMGIS. The hydrological model and the sediment yield model were coupled together and the whole model was also coupled closely with the GIS.The distributed function of the model was achieved finally.
