FIELD MEASUREMENT OF HEAT MITIGATION AND AIR PURIFICATION EFFECTS OF PLANTED AREA IN A CITY

Abstract

The prupose of this study is to understand the heat mitigation and air purification effects of planted park by measuring the nitrogen oxide, temperature and relative humidity in the residential and planted park. The results are following; ・ Planted park area is cooler and more humid than the residential area in the night. ・ Planted park area is warmer than the residential area at dawn. ・ The density of nitrogen oxide along the traffic road is higher than the planted park area. ・ But the difference of temperature, relative humidity and density of nitrogen oxide between residential areas and planted park ones is very small.
