摘　　要：对我国现有水资源质量评价方法作了总结评述,对其中的确定性评价方法进行实例计算分析。总结现有方法的不足,以国家水环境质量标准为基础,提出了改进的分级评分水质评价方法。应用该改进方法进行实例验算。结果表明,该改进的方法统一了评判标准,提高了结果的可比性,兼具污染指数法和分级评分法的优点,计算简便,应用性强。A review on the evaluation methods for water quality in China is presented and a water evaluation example is performed using the deterministic methods.Then,by analyzing the deficiency of the present methods,an improved water quality evaluation method of grading score,is proposed based on the national water quality specification.Finally,a practical water quality evaluation case is shown based on the above-mentioned improved method.The results indicate that the use of this improved method can unify the evaluation criterion and thus improve the reliability of the evaluation results;the improved method takes the advantages of both pollution index method and score-and-classify method,and also be simple and feasible itself.
