Among cancers,lung cancer is the most common cause of death in China.For the prevention and control of lung cancer,it is necessary to investigate the spatial and temporal distribution of lung cancer mortality,as well as the changes in the trend and the affect-ing mechanism.Based on statistics and auto-correlation analysis,this paper studied the spatial and temporal distribution of lung cancer mortality in Yuhui District,Bengbu,Huaihe River Basin,from 2017 to 2020.In addition,Spearman's Rank Correlation Assessment Model and Geographic Detector Model were used to examine the relationship between environmental factors and lung cancer mortality to identify impact factors and their mechanisms.The findings indicated that:1)from the characteristics of temporal distribution,the number of lung cancer deaths exhibited a linear growth tendency,with the highest mortality in winter;2)from the characteristics of spa-tial distribution,lung cancer mortality showed a strong spatial agglomeration form,concentrating on two clustering areas,located in the old city and the central city of Bengbu,near the Huaihe River;3)from the point of view of the whole research area,there were 15 im-pact factors with significant correlation in the built and natural environment factors.The significant impacting factors in the built envir-onment included land use,road traffic,spatial form and blue-green space,which could indirectly affect lung cancer mortality,while air pollution and temperature constituted the significant impacting factors in the natural environment;4)the influence of screened environ-mental factors on lung cancer mortality was different.Spatial stratified heterogeneity assessment,the interaction among environmental factors demonstrated statistical significance,it was found that the interaction between environmental factors in pairs had a significant en-hancement effect on lung cancer mortality.To some extent,urban planning and policies could reduce lung cancer mortality.
