Abstract

With the continuous development of cities and the rapid increase of urban population, the problem of air pollution in cities has become increasingly prominent. Improving the living environment has become a hot topic at present. As one of the areas where people stay the longest, the street is directly connected to the atmosphere and is most affected by air pollutants. To explore the current research status and hotspot evolution of pollutants in urban street valleys, a bibliometric method was adopted. Through the classification and statistics of 182 papers in the WOS core collection on the diffusion mechanism of pollutants in street valleys, the research on street valley greening and pollutant emission characteristics, and the improvement of air quality in street valleys, The existing research results are summarized and sorted out from multiple aspects such as the number of published articles, co-cited journals of the literature, publishing institutions, and co-occurring keywords. The analysis of 182 literatures in the WOS core collection shows that the papers on urban street valley greening and pollutants began in 2012, and the number of published papers has shown a trend of increasing year by year and then decreasing. The research content mainly focuses on fields such as environmental science and architecture; The key words co-occurrence network graph reveals that the research hotspots in this direction are developing towards the wind environment. The research on the impact of urban street and valley greening on pollutant diffusion started relatively early. It is suggested that further related research be carried out in the fields of atmospheric science, physics, ecology, etc., to make greater contributions to improving the urban living environment.
