| 摘 要： | 在临安城区选择居住区、道路、街旁、带状公园、学校、广场六个不同功能区绿地作为研究对象,通过进行负离子浓度、温湿度、光量子、噪声、粉尘以及二氧化碳等指标含量的测定,以此了解各功能区的生态效益状况,结果表明:负离子与粉尘呈显著性正相关(P<0.05)、与湿度呈极显著性正相关(P<0.01),与温度呈极显著性负相关(P<0.01);湿度与温度呈极显著负相关(P<0.01)。城区内负离子浓度苕溪最高,最低的是浙江农林大学东湖校区,苕溪是学校的1.9倍。二氧化碳浓度浙江农林大学东湖校区最高,最低的为城中街,学校是城中街的1.6倍;粉尘含量最高的是人民广场,最低为苕溪,人民广场是苕溪的1.26倍;而噪声最高是人民广场,最低的是浙江农林大学东湖校区。六种功能绿地中,空气负离子含量、噪声大小差异性最显著(P<0.01),二氧化碳、粉尘、光照及湿度差异性较显著(P<0.05),但是空气温度的差异性不显著。

| Abstract: | Green space in the six different functional areas of urban Lin’an including residential area, road, street side, street park, school and square were selected as the research object, and through the testing of the indicators like aero-anion concentration, air temperature, relative humidity, light intensity, noise, dust and carbon dioxide, the ecological benefits of these functional areas came to be known. The results showed a significant positive correlation （p〈0.05） between the aero-anion concentration and dust, a significant positive correlation （p〈0.01） between the aero-anion concentration and the relative humidity, a significant negative correlation （p〈0.01） between the aero-anion concentration and air temperature and a significant negative correlation （p〈0.01） between relative humidity and air temperature. In the urban area, the aero-anion concentration was the highest in Tiaoxi, and the lowest in the East Lake Campus of Zhejiang Agriculture Forestry University, the highest being 1.9 times of the lowest; the carbon dioxide was the highest in the East Lake Campus of Zhejiang A F University, and the lowest in Chengzhong Street, the highest being 1.6 times of the lowest; dust was the highest in People’s Square, 1.26 times of the lowest in TiaoXi River while the noise was the highest in People＇s Square and the lowest in the East Lake Campus of Zhejiang A F University. In the green space of the six functional areas, there was a significant difference （p〈0.01） between aero-anion concentration and noise, and a significant difference （p〈0.05） among carbon dioxide, dust, light intensity and relative humidity, but no significant difference in air temperature. |
