Abstract:

In order to explore the air quality situation in bamboo forest and the relationship of air quality and environmental factors, the author researched the diurnal variation of aero-anion concentration in bamboo forest, and analyzed the relationship between aero-anion concentration and temperature, relative humidity and other environmental factors further. The tests completed by List-style hygrometer TES-1362 made in Taiwan and aero-anion concentration detector ITC-201A made in Japan. The results showed that the aero-anions concentration of 3 kinds of bamboo from February to May. The ground bamboo was 357.58/cm3. The single bamboo was 484.75/cm3. The clumping bamboo was 398.3/cm3. The average aero-anions concentration of bamboo was 413.54/cm3. The general trend of the aero-anions concentration in 3 kinds of bamboo increased firstly and then declined and was positively correlated with temperature and was negatively correlated with humidity.
