摘　　要：将超球向量机方法引用到水环境质量评价中,并应用该方法与标准指数法分别对细河水体进行了评价。结果表明,超球向量机评价方法对监测值处于分类重叠区域的水质分类要优于标准指数法,评价结果更客观,具有较好的泛化能力,说明超球向量机法可以用于水环境质量评价,具有很好的研究前景。The method of hypersphere vector machine was adopted for quality assessment of water environment, and the assessment on a practical case was conducted effectively by this method and standard index method. The results indicated that the hypersphere vector machine evaluation method was superior to standard index method for the water quality classification of overlapping area by the monitoring data, the assessment result was more objective, and generalization ability was satisfied. It indicated that the method of hypersphere vector machine could adopt in the quality assessment of water environment, and there is a better research prospect.
