摘　　要：随着工业技术的发展,空气质量逐渐恶化,空气污染已经发展为全人类共同面对的严峻问题。随着监测技术的提升,空气污染数据迅速增加,人们对空气质量时空变化的研究逐渐向年际及年代际时间尺度靠拢。而现阶段对年际时间尺度空气质量评价的方法较少,常用年均AQI作为评价指标。由于AQI是单一污染物指数,抵消了多种污染物的累计效应,产生的模糊信息会掩盖其他污染物对健康的实际影响。因此,该研究基于中国AQI计算方法提出了一种基于多权重的特定的年际时间尺度空气质量评价模型——综合空气质量指数(CAQI),用于修正中国空气质量指数在年际空气质量评价中的缺陷。通过对模型验证发现该模型具有良好的性能,在年际时间尺度空气质量评价中效果较好,具有更高的合理性。With the improvement of monitoring technology and the rapid increase of air pollution data,the research on the temporal and spatial variation of air quality gradually approaches to the interannual and interdecadal time scales.At present,there are few methods to evaluate air quality on the interannual time scale,and the average annual air quality index(AQI)is commonly used as the evaluation index.Because AQI is a single pollutant index,it cancels out the cumulative effects of multiple pollutants,and the resulting fuzzy information can obscure the actual health effects of other pollutants.Therefore,based on the existing AQI calculation method,this study proposed a specific interannual time scale air quality evaluation model based on multi-weight-comprehensive air quality index(CAQI),which is used to correct the defects of China’s air quality index in the interannual air quality assessment.Through the validation of the model,it is found that the model has good performance,and it has better effect and higher rationality in the interannual air quality assessment.
