西径山森林公园夏季空气负离子日变化
Daily variation of air anions in Mount Xijing Forest Park
摘要
Abstract
The air anions concentration, temperature, relative humidity and light intensity of 6 plant communities in Mount Xijing Forest Park were measured and compared with the data of park entrance square and Lin' an People' s Square to study the impacts of different community types and environmental factors on the concentrations of the air anions. The results showed that the air anions concentrations of the 6 communities were much higher than that of the two squares. The average environmental quality of the Mount Xijing Forest Park was much better than the downtown. The air anion concentrations were sorted as Toona sinensis-Phoebe sheareri>Cinnamomun amphora-Osmanthus fragrance >Cunninghamia lanceolata>Schima superba-Cyclobalar-nopsis glauca >C. Glauca - Castanopsis sclerophylla >Phyllostachys pubescens. The air quality of 5 communities reached the cleanest standard. According to the diurnal variation curve between 8: 00 a.m. And 5 p.m., the air anion concentration had double peaks between 9: 00 a.m. - 10; 00 a.m. And 1: 00 p.m. - 2: 00 p.m. A correlation analysis showed an extremely significant (P<0.01 )positive correlation between air anion concentration and relative humidity, a significant(P<0.05)negative correlation between air anion concentration and temperature and no significant correlation between air anion concentration and light intensity.关键词
