Objective

To construct a land use regression (LUR) model for particulate matter with an aerodynamic diameter ≤2.5 μm (PM2.5) in Zunyi.

Methods

Collect and organize hourly PM2.5 monitoring data from routine air quality monitoring stations from January 1, 2020 to December 31, 2020, as well as geographic information data such as land use, roads, population density, altitude, and meteorological factors in Zunyi. Conduct multiple stepwise linear regression with PM2.5 concentration as the dependent variable and geographic information variables and meteorological factors as independent variables to construct a model. Use leave-one-out cross validation (LOOCV) to verify the performance of the model.

Results

The model formula is Y=72.656-0.026×altitude-0.009×NDVI-0.62×average temperature-383.512×average precipitation. The model had R2=0.74, adjusted R2=0.72, cross validation R2=0.69, RMSE=3.51, and a high spatial resolution (250 m×250 m).

Conclusion

The model fits well and fully reflects the influencing factors of PM2.5 spatial distribution in Zunyi. It can be used to estimate individual exposure levels and provide strong support for environmental health epidemiological research.
