Abstract:
Garden or urban street construction planting plants with high pollution resistance can not only play a remedial role in the surrounding environment, such as reducing dust and noise, absorbing toxic gases and substances, but also beautify the environment and play a role in shade and soil preservation, climate regulation, etc. Three street trees, Cassia nodosa, Cinnamomum camphora and Spathodea campanulata were selected as the objects, conductivity, chlorophyll content and plant leaf dust retention were used to reflect the pollution resistance characteristics of these three plants. The results showed that C. Camphor had the strongest anti-pollution characteristics, followed by Spathodea Campanulata, and Cassia Nodosa was the weakest. This conclusion provides theoretical guidance for the selection and utilization of street trees.
