摘要
在分析影响灌溉用水水质因素的基础上,选择酸度、碱度和矿化度为评价因子,建立了灌溉用水水质评价的投影寻踪分析模型,采用蚁群算法对评价模型进行优化,并将该模型应用于某灌区灌溉水水质的评价。研究表明,用投影寻踪回归分析法进行水质评价,避免了传统评价方法由于主观原因造成的误差,评价结果合理可信、方法简单,为灌溉用水水质的评价提供了新途径。
The acidity,alkalinity and mineralization degree were selected as evaluation factors based on analyzing the factors of affecting irrigation water quality to establish the model of projection pursuit for evaluating water quality and then the model was optimized by Ant Colony Algorithm.The evaluation result from evaluating the irrigation water quality by the model with a simple way was more reasonable and reliable than that by the conventional evaluation method.The model of projection pursuit provides a new method for evaluation of irrigation water quality.
