南昌市大气污染与居民肺癌发病率的灰色关联分析

Grey Correlation Analysis of Air Pollution and Lung Cancer Incidences in Nanchang City

研究结果表明:对比SO2、NO2、PM10,霾日数与肺癌发病率的灰色综合关联系数最高,南昌市近15年来霾日数与肺癌发病率的灰色综合关联系数为0.783 8,滞后期为5年。研究旨在为保护公众健康提供科学依据,本地气象部门可以利用长期的历史数据优势,不断深化历史资料分析,结合环保、医疗等各部门的数据开展霾污染与人群健康相关研究,为政府科学开展污染治理提供决策参考。

In view of the hot issue of environmental air quality and human health, based on the meteorological observation da- ta, environmental monitoring data, lung disease patient data, this paper tries to use gray correlation analysis method to study relationship of atmospheric pollution and residents of lung cancer incidence rate in Nanchang city in nearly 15 years. The results show that ： Compared to SO2, NO2, PM10, the comprehensive grey correlation coefficients of haze days and lung cancer incidence rate is the highest one, the comprehensive grey correlation coefficients of haze days and lung cancer incidence rate in Nanchang city in nearly 15 years is 0. 7838, lag for a period of 5 years. This study aims to provide a scientific basis for the protection of public health and the local meteorological department should use the advantage of long - term historical data, carried out research on haze pollution and population health by deepening of historical data analysis and combining with the data from environment and medical departments. Such study can provide suggestion for government to carry out pollution control and make decisions.
