Correlation between leaf functional traits of Euonymus japonicus in the environment polluted by atmospheric particulate matter. PM: atmospheric particulate matter, LT: leaf thickness, CCI: chlorophyll content index, SLA: specific leaf area, LDMC: leaf dry matter content, LTD: leaf tissue density, SD: stomatal density. “*” indicate that the indicators have reached a significant difference at the p < 0.05 level
