投影寻踪分类模型评定相似流域

Projection Pursuit Method for Assessing Analogy Basins

  • 摘要: 简要介绍了基于遗传算法的投影寻踪分类模型,并将其首次用于水文计算中相似流域的选择。对一个实例的应用研究表明,此模型能给出一个综合考虑流域中多指标间复杂关系的特征指标,利用这个指标取得合理的评定结果,且新模型计算过程简单,结果直观,为水文计算中水文比拟法提供了新思路。

     

    Abstract: The paper briefly presents the projection pursuit classification model based on genetic algorithm and first introduces it to the choices of analogy basins in hydrologic calculation.Applying the projection pursuit model to research a practical case,we found that it can construct a characteristic index to discover tomprehensively complex relationship among several indexes of analogy basins.The new model is qualified and provides a new approach for assessing hydrologic analogy.
