| To deepen the quantitative understanding of the air purification function of vegetation in the
context of land use change, this study reviewed the trends of land use change in Lishui City from 2000 to 2020, assessed the dynamic changes of vegetation′s ability to remove PM2.5 by using a dry deposition
model. Additionally, the study used a geographically weighted regression model to analyze the primary
drivers of land use changes and utilized the PLUS model to spatially predict the land use patterns and
vegetation PM2.5 removal capabilities under different management scenarios by 2030. The results showed
that the primary type of land use change from 2000 to 2020 was the encroachment of construction land on
forest areas driven by socio-economic factors; under the joint influence of urbanization and air pollution
control, the dry deposition rate of atmospheric PM2.5 by vegetation in Lishui area decreased by 3.0% in
2020 compared to 2000, and the dry deposition flux decreased from 0. 36 g/ (m2·a) in 2000 to 0. 26 g/
(m2·a) in 2020; natural environmental factors had the strongest explanatory power for the spatial variation
in the PM2.5 removal capacity of vegetation; under a natural development scenario, the PM2.5 removal
capacity of vegetation by 2030 would continue to decline by 1.6% compared to 2020, while an ecological
protection scenario would see an increase of 1.3%. In summary, from 2000 to 2020, the area of cultivated
land, forest land and grassland in Lishui City showed a shrinking trend, and the area of water and
construction land expanded, which was mainly driven by socio-economic factors; the dry deposition removal
capacity of vegetation for atmospheric PM2.5 continued to decline, and its spatial differentiation was
mainly related to natural environmental factors; in the future scenario, under the current development
model, the dry deposition removal capacity of vegetation for atmospheric PM2.5 would continue to decline,
while the dry deposition removal capacity would increase under the eco-development scenario. |
