Abstract:

The daily variation, difference of various site conditions and correlation of temperature, humidity, atmospheric particulate matter of 2.5 μm diameter or less and 10 μm diameter or less (PM 2.5, PM 10), negative air ions and noise were monitored for 14 days, at sites both on and off the golf course. The level of every factor in the golf course was better than outside the golf course, and the purification efficiency of compound green space with arbor-shrub-grass was superior to arbor-grass and grass. Daily variation of temperature and relative humidity showed a single peak and trough pattern, respectively. Compared with the outside, the daily average temperature in the golf course was 2.1℃ lower, the relative humidity increased by 9.2%. The daily variation of PM 2.5 and PM 10 showed a bimodal trend, rising in the morning, falling to a minimum in afternoon, and then gradually increasing. The daily purification rates of them were 25.9% and 26.6%, respectively, on the golf course. These two measures had a highly significant correlation, and also had a highly significant positive correlation with temperature and negative correlation with humidity. The level of negative air ions in the golf course was 4.95 times higher than outside the golf course, which had a similar but opposite diurnal pattern and correlation with temperature and humidity to that of particulate matter. The noise in the golf course was significantly (11.8%) lower than outside the golf course.
