摘要： 水资源开发利用程度评价是一个由多指标组成的复杂巨系统,其难点是如何合理地建立评价该系统的数学模型。当前的评价模型随着评价内容的不同而变化,精度较难控制。为解决单项水资源开发利用程度评价指标评价结果的不相容问题,提高水资源开发利用程度综合评价各层次的分辩力和评价模型的精度,论文采用大样本数据,利用投影寻踪、遗传算法、插值型曲线和水资源开发利用程度评价标准,为水资源开发利用程度综合评价建立了一种新的数学模型———遗传投影寻踪插值模型(GPPIM)。实例研究表明,GPPIM建模方法直观、可靠、精度高,既有较强的分类功能,又有较好的排序功能,可广泛应用于各种水资源问题的综合评价。

关键词: 水资源开发利用程度, 综合评价, 插值, 投影寻踪, 遗传算法

Abstract: It is difficult to establish the mathematics model and to control the precision of the assessment models in the multi - index complex system of water resources development.In order to solve the nonunniformity indexes problem and to raise the model precision for water resources development level assessment,a new model,genetic projection pursuit interpolation model(GPPIM),is presented for water resources development level assessment by using projection pursuit,genetic algorithm,interpolation technique and lots of sample data from the assessment standards of water resource development level.And its detailed step is developed.GPPIM remarkably improves calculation accuracy.The results of case studies in Xian show that GPPIM has the features of direct,credibility and effective.It proves a good assessment method in both classifying and arrangement,and could be applied to various water resources comprehensive assessment issues.

Key words: development of water resources, comprehensive assessment, interpolation technique, projection pursuit, genetic algorithm
