基于遥感反演的绿色空间景观格局对气溶胶污染的影响

气溶胶对人类的生命健康具有重要影响,绿色空间被认为是缓解气溶胶污染的重要生态设施.既往研究集中于单个污染因子与土地利用的相关研究,但对绿色空间景观格局与综合空气污染物空间规律的定量化研究较少.以武汉市为例,基于遥感影像,利用ENVI、ArcGIS提取绿地和AOD数据,运用Fragstats计算绿色空间景观指数,从统计学...

The Impact of Green Space Landscape Patterns on Aerosols Pollution Based on Remote Sensing Inversion

: Aerosols have an important impact on human life and health, and green spaces are considered to be important ecological facilities to alleviate aerosol pollution. Previous studies focused on the correlation between individual pollution factors and land use, but there were few quantitative studies on the landscape pattern of green spaces and the spatial laws of comprehensive air pollutants. Taking Wuhan as an example, based on remote sensing images, using ENVI and ArcGIS to extract green space and AOD data, and using Fragstats to calculate the green space landscape index, the relationship between the green space landscape pattern and AOD was studied from the two aspects of statistical law and spatial distribution law. The research found that: 1) Both the green space landscape index and AOD have significant spatial agglomeration characteristics; 2) The core landscape index indicators for green space landscape patterns to alleviate aerosol pollution are CA, PLAND, LPI, COHESION, and AI; 3) Based on geographically weightedregression, the impact of the green space core landscape index on the distribution of AOD concentration has spatial differences. A regulation strategy for the green space core landscape index to alleviate aerosol pollution is proposed. It aims to provide a reference for ecological planning and design of green space from the perspective of mitigating aerosol pollution, and provide a theoretical reference for the construction of a healthy living environment and public health safety
