| Abstract: |
| This paper focuses on the six spaces composed of different landscape elements in an urban park to conduct on-site measurement. By measuring the PM2.5 concentration, air temperature, relative humidity, wind velocity and direction, and analyzing the relationship between the composition of landscape elements and PM2.5 concentration in different spaces, we explore the correlations between spatial meteorological factors and PM2.5 concentration. The results show that: 1) There are significant differences (P<0.05) in PM2.5 concentrations among landscape spaces. 2) There is a significant negative correlation (R=－0.966) between PM2.5 concentration and green volume (D).
