摘要
应用地理信息系统 (GIS)技术 ,在MapInfo平台上建立分布式流域水文模型 ,模拟赣江流域的径流过程 ,探讨月水量平衡模型参数的地区分布规律 ,计算各网格的径流深和水资源量 ,并与实测值进行比较 .结果表明模拟径流深与实测径流深吻合良好 ,年径流的相对误差可控制在 10
On the basis of the geographical information system(GIS) technique and MapInfo software, a distributed two parameters monthly water balance model is developed. The relationship between model parameters and GIS information of the basin as well as the parameterization procedures are discussed and described. The model is used to simulate the grid runoff in the Ganjiang River basin. The comparison between simulated and observed runoff results shows that the model has high efficiency and low relative error.
