Investigating the Long-Term Relationship between Aerosol Optical Thickness and Land Use/Cover Change in Guangxi Coastal Cities, China

Land Use/Cover Change (LUCC) has an impact on AOD to a certain extent. It is of great significance for ecological environment and public health pay attention explore the response mechanism LUCC. Based remote sensing satellite technology, using landsat8 MODIS data, this paper analyzes correlation between different land use types in Beibu Gulf coastal urban belt under background wide-scale region long time series, further discusses difference value contribution level each LUCC AOD. The results show that: 1) there positive PM concentration cultivated land, water area other coefficient increases turn, R 0.812, 0.685, 0.627, 0.416, respectively, which indicates that increase extent; 2) significant negative forest -0.924, decrease woodland important factor atmospheric particulate matter study from 2015 2019; 3) through analysis method, largest, followed by smallest 2015-2019, mode closely related can be helpful reasonably plan scientifically optimize structure. effectively reduce air pollution particles.
