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

Abstract: |
: 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 |
