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月份地被竹、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种竹子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。

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.
