[Comparison of spatial-temporal evolution of habitat quality between Xinjiang Corps and Non-corps Region based on land use].

Regional habitat quality is an important indicator of ecosystem health. Understanding land use change and habitat quality will help protect biodiversity and build an ecological security pattern. We used the InVEST model to quantitatively evaluate the habitat quality of the Xinjiang Corps and Non-corps Region based on land use data of 1990, 2000, 2010 and 2018, and further analyzed the similarities and differences of the spatiotemporal distribution.

[Simulation of the Spatio-temporally Resolved PM Aerosol Mass Concentration over the Inland Plain of the Beijing-Tianjin-Hebei Region].

In recent years, haze pollution in China is becoming increasingly serious, especially in the Beijing-Tianjin-Hebei region. In order to identify the temporal and spatial distributional characteristics of PM aerosol mass concentration in the region, this study selected the inland plain of the Beijing-Tianjin-Hebei region as the research area, and used MODIS AOD as the main predictor in a mixed effects model to establish the daily relationship of AOD-PM in the study area, from 2013 to 2014. The model was validated by a ten-fold cross validation method.
