摘　　要：基于环境空气的信息不确定性特点,运用未确知数学理论,建立了城市环境空气质量评价的未确知测度模型。根据未确知测度的大小,确定样本所属的质量级别及样本间的优劣排序。以唐山市为例,运用所建模型对其环境空气质量状况进行了评价。研究表明,未确知测度模型对于多指标的城市空气质量评价,理论上是可行的,结果是可信的。Based on the information uncertainty of air environment,the uncertain measure model in the air quality appraisal of urban environment is established with uncertain math theory. The model will determine the mass level and quality of selected samples according to the uncertainty. The model was applied to appraise the air quality in Tangshan as an example. The example analysis indicated that the multi-object air quality appraisal of urban environment using the uncertain model is theoretically feasible and the measured results are credible.
