Effects of urban functional fragmentation on nitrogen dioxide (NO₂) variation with anthropogenic-emission restriction in China.

ABSTRACT: Urban functional fragmentation plays an important role in assessing Nitrogen Dioxide (NO₂) emissions and variations. While the mediated impact of anthropogenic-emission restriction has not been comprehensively discussed, the lockdown response to the novel coronavirus disease 2019 (COVID-19) provides an unprecedented opportunity to meet this goal. This study proposes a new idea to explore the effects of urban functional fragmentation on NO₂ variation with anthropogenic-emission restriction in China. First, NO₂ variations are quantified by an Autoregressive Integrated Moving Average with external variables-Dynamic Time Warping (SARIMAX-DTW)-based model. Then, urban functional fragmentation indices including industrial/public Edge Density (ED) and Landscape Sh
