【摘要】 利用实测资料对贵阳市花溪风景区不同植被环境空气负离子浓度及空气清洁度进行研究及评价。结果表明:花溪风景区空气负离子浓度较高,空气质量好;不同植被环境中,其空气质量具有显著的差别,其顺序为:马尾松林>中国梧桐林>火棘林>草地;空气负离子浓度具有明显日变化规律,清晨高午后低。更多还原

【Abstract】 Aero-anion concentration and air quality of different vegetation in Huaxi scenic area of Guiyang city were analyzed in this study. Results showed that:1)Concentration of aero-anion was high,and air quantity was good in Huaxi scenic area. 2)Aero-anion concentration differed obvi- ously in different vegetation surroundings with order of:Pinus massoniana Lamb forest > Firmiana simplex forest > Pyracanthafortuneana forest > Meadow. 3)There was a significant daily variation of aero-anion concentration with high concentration in early morning and low concentration in the afternoon.更多还原
