竹林空气负离子浓度状况及变化规律研究

为了探讨竹林的空气质量情况以及空气质量和环境因子的关系,采用台湾TES-1362数字式温湿度测量仪和日本ITC-201A型智能便携式空气负离子测定仪,对不同竹种的空气负离子浓度进行测定,探讨竹林空气负离子浓度的日变化规律,并进一步分析空气负离子浓度与气温、空气相对湿度等环境因子之间的关系。结果表明,2—5月地被竹、单生竹、丛生竹3种竹的空气负离子浓度分别为357.58个/cm3、484.75个/cm3、398.3个/cm3,而竹类平均的空气负离子为413.54个/cm3。3种竹林空气负离子浓度的日变化规律总趋势是先升高再降低;空气负离子浓度与气温呈正相关,与湿度呈负相关。

Study on the Aero-anion Concentrations and the Change Law of Bamboo Forest

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.
