| 摘 要： | 针对灌溉水质单指标评价的缺点和现有综合评价方法存在的问题,将分辨能力强、不易丢失信息的物元模型引入到灌溉水质的评价中,并采用主观权重(AHP法)和客观权重(熵权法)综合的方法解决关联度计算时权重不易确定的问题。将基于综合权重的灌溉水质评价物元模型应用于实例分析,5个水样的灌溉水质分别为Ⅱ级、Ⅲ级、Ⅴ级、Ⅴ级和Ⅲ级,与属性综合评价法的评价结果基本一致,说明物元模型用于灌溉水质综合评价方法可行、结果可信。

| Abstract: | For the shortcoming of single-index assessment to irrigation water quality and the problems of some comprehensive evaluation methods,the matter-element model which has the distinguish ability and fidelity information is introduced to quality evaluation of irrigation water in this paper.Subjective weight(AHP method) and objective weight(entropy value method) are used to determine combined weights when calculating the connect degree in the assessment.The matter-element model based on combined weights is used ... |
