于2010年12月-2011年11月,对散生竹、丛生竹、地被竹等3种竹群落的空气负离子浓度、可吸入颗粒物浓度进行监测,采用单极系数( q)、空气质量评价指数( CI)和森林空气离子评价指数( FCI)对空气质量进行评价,并探讨竹群落空气负离子浓度与温度、湿度的相关关系。结果表明:竹群落空气负离子浓度具有明显的日变化特征:波谷和波峰交替出现的单峰曲线,在8∶00-18∶00时段内,负离子浓度在8∶00处于最高水平,而在12∶00处于最低水平;空气负离子浓度随季节变化呈现出一定的规律性:春季很低,到夏季上升很快,而到秋季则又下降。竹群落可吸入颗粒物浓度的日变化:从8∶00开始可吸入颗粒物浓度开始缓慢下降,到16∶00达到最低,之后又缓慢上升;随季节变化则为冬季>秋季>春季>夏季。空气负离子浓度均值为丛生竹>散生竹>地被竹。空气负离子浓度总体水平均超过700个· cm-3,有益于人体健康,具有保健功能;空气质量评价系数CI均值为0.892,空气质量等级总体达到A级水平,即清洁程度。空气负离子浓度与气温、相对湿度呈二次曲线相关关系。
于2010年12月-2011年11月,對散生竹、叢生竹、地被竹等3種竹群落的空氣負離子濃度、可吸入顆粒物濃度進行鑑測,採用單極繫數( q)、空氣質量評價指數( CI)和森林空氣離子評價指數( FCI)對空氣質量進行評價,併探討竹群落空氣負離子濃度與溫度、濕度的相關關繫。結果錶明:竹群落空氣負離子濃度具有明顯的日變化特徵:波穀和波峰交替齣現的單峰麯線,在8∶00-18∶00時段內,負離子濃度在8∶00處于最高水平,而在12∶00處于最低水平;空氣負離子濃度隨季節變化呈現齣一定的規律性:春季很低,到夏季上升很快,而到鞦季則又下降。竹群落可吸入顆粒物濃度的日變化:從8∶00開始可吸入顆粒物濃度開始緩慢下降,到16∶00達到最低,之後又緩慢上升;隨季節變化則為鼕季>鞦季>春季>夏季。空氣負離子濃度均值為叢生竹>散生竹>地被竹。空氣負離子濃度總體水平均超過700箇· cm-3,有益于人體健康,具有保健功能;空氣質量評價繫數CI均值為0.892,空氣質量等級總體達到A級水平,即清潔程度。空氣負離子濃度與氣溫、相對濕度呈二次麯線相關關繫。

During December, 2010~November,2011,this paper monitored the aero-anion concentration and inhalable particle con-centration of scattered born bamboo , bushes bamboo and cover bamboo by aero-anion measuring instrument .It also discussed the re-lationship between aero-anion concentration and temperature and humidity .The research results showed that the aero-anion concen-tration had evident daily changes characteristics with the changes of time .There was a single-peak curve with peaks and troughs ap-peared alternately , during 8∶00~18∶00, the aero-anion concentration was highest at 8∶00 am and was lowest at 12∶00 am.The aer-o-anion concentration showed a certain regularity that it was very low in spring ,increased quickly in Summer , and decreased in Au-tumn.The bamboo community inhalable particle concentration daily change was that the inhalable particle concentration began de -creasing at 8∶00 am slowly, and the minimum appeared at 16∶00 am and then increased slowly .The seasons change was winter >au-tumn>spring>summer.Air negative ions concentration overall levels were more than 700 ones· cm-3 , beneficial to human body health, had the health functions; the air quality evaluation coefficient CI mean value was 0.892, The levels of them respectively were A level ( clear degree ) .Aero-anion concentration , temperature and relative humidity appeared a quadratic curve .
