无资料地区径流预报方法比较与改进

 利用新安江模型对无资料地区径流预报方法进行研究。以澳大利亚东南地区的210个流域为例，首先利用距离相近法、属性相似法和回归法进行预报，并对3种方法进行比较，结果表明，距离相近法精度最高，属性相似法次之，回归法效果较差。然后在距离相近法和属性相似法的基础上提出了综合相似法，使得模拟结果进一步提高。此方法可对中国无资料或者资料缺乏流域进行水文预报。

Comparison of Regionalization Approaches for Runoff Prediction in Free of Observational Data Catchments

This paper uses a conceptual rainfall-runoff model,the Xinanjiang model,to evaluate regionalization approaches using 210 catchments in south-east Australia as examples.Three regionalization approaches are compared: spatial proximity,physical similarity and regression.The results show that: spatial proximity provides the best regionalization solution;the physical similarity approach is intermediary;the regression approach is the least satisfactory.A new method,integrated similarity,is proposed by combining t...
