摘　　要：基于灰色论原理,本文用关联度模型综合判定地面水质的类别,其结果与模糊综合评判模型M相似评判及贴近度评判模型进行了比较。在此基础上,本文提出地面水环境质量综合评判的环境距离模型,该模型中,以几何环境距离G(d)识别水质差别,以算术环境距离A(d)判定同类水质的优劣,以线上距离d(+)定量地表达超标程度,从而使地面水环境质量综合评判中的三个主要问题统一于一个模型之中。In view of grey theory principle, the rclative degree model is used to comprch- ensively evaluate the type of the earth surface water quality in this paper, and the result is compared with fuzzy comprehensive evaluation model M(·, ), similar evaluation, as well as closeness degree model. Based upon this, the environ- mental distance model used to comprehensively evaluate the earth surface water qnality is put forward in the paper. According to this model, the geometric environ- mental distance G(d) is ussed to distinguish the classification of the water quality, the arithmetic environmental distance A(d) can evaluate the advantage or disadvantage of the water quality of the same kind and the upon-line distance d(+) can quantitatively describe the super-standard degree so that three basic problems in the comprehensive evaluation of the earth surface water environmental quality are unified into one model.
