Projection Pursuit Method for Assessing Analogy Basins

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.
