| 摘 要： | 基于新安江模型,利用GIS技术和相似性分析开展流域无资料情况下的水文模拟。在提取流域特征值的基础上,通过相关分析、聚类分析等方法判定相似流域,有效地分析了模型参数与流域特征的关系,重点论证了相似流域参数移植的可行性。通过相似性分析,发现相似流域的水文参数在几何空间上距离较近。基于此结论,本文对无资料地区进行了水文模型参数的确定,并取得了较好的模拟结果。

| Abstract: | Based on XAJ model, the GIS technology and similarity analysis were used for hydrological simulations in the ungauged basins. Through correlation and cluster analysis methods, this paper determined the similar basin by the basin characteristics extraction, analyzed the relationship between the model parameters and watershed characteristics, and expounded the feasibility of parameter transformation method for the similar watersheds. The analysis of hydrological similarities indicate that the distances on the parameters of two similar watersheds are mostly small and close in the geometric space. Based on this conclusion, the hydrologic model parameters of ungauged basins were determined, and the good simulation results were achieved. |
