承德超贫钒钛磁铁矿规模化开采对区域大气环境的影响
The impact of large-scale mining of ultra-poor vanadium-titanium magnetite on regional atmospheric environment in Chengde
摘要
Abstract
This study utilizes satellite remote sensing technology to monitor the atmospheric pollution caused by high-intensity mining in the ultra-poor vanadium-titanium magnetite mining area of Chengde.The research results show that spatially,Aerosol Optical Depth(AOD)level in mining area is significantly higher than the background value,and the extreme value difference between the two is particularly pronounced in summer.Temporally,the interannual AOD showed a downward trend after peaking in 2014.Seasonal characteristics indicate that AOD is highest in summer,at 0.409,followed by spring and winter,and lowest in autumn,at 0.151.In terms of influencing factors,iron ore output continued to increase from 2018 to 2022,and rainfall decreased significantly in 2022.Nevertheless,the regional AOD presented an overall downward trend,indicating that atmospheric pollution prevention and control measures have effectively offset the adverse impacts of industrial mining activities and unfavorable meteorological conditions factors.By analyzing the spatiotemporal variation characteristics of atmospheric aerosols in Chengde typical low-grade vanadium-titanium magnetite mining areas,and clarified the response relationship between mining development and atmospheric environment.The research findings can provide theoretical basis and data support for the comprehensive atmospheric environmental governance and green development of mining areas.关键词
