Six representative areas of different types of urban green spaces in the main urban area of Nyingchi City were selected for NAIs observation and measurement. The results demonstrated that the NAI concentration in summer was significantly higher than the other three seasons in the study area. The NAI concentration in Fujian Park was significantly higher than the other observation sites, in the order of Fujian Park &gt; the green space of Guangfu Avenue &gt; Wetland Park of Happiness Community &gt; the ecological scenic area of Biri Holy Mountain &gt; Gala Peach Blossom Village &gt; the scenic area of Cypress King\u2019s Garden. Pearson\u2019s correlation analysis showed that the NAI concentration was positively correlated with positive air ions and humidity, while humidity was positively correlated with NAIs and positive air ions, but negatively correlated with temperature and CO\n                    <jats:sub>2<\/jats:sub>\n                    concentration (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.05).
