| 摘 要： | 利用KEC-900负离子检测仪对黑龙江省森林植物园不同类型林分空气负离子浓度进行定点观测。结果表明:园内各类型林分空气负离子浓度日变化多存在1~2个峰值,峰值出现的时间为早晨或晚上,负离子浓度日最高值出现在白桦林,达到1 815个cm~(-3)。负离子浓度年变化分别在7月和9月存在峰值,7月红皮云杉林分空气负离子浓度最高,达到1 284个cm~(-3)。

| Abstract: | The concentration of negative-ion was observed on different types of stand by using KEC900 anion detector in Heilongjiang Forest Botanical Garden.Result shows that diurnal variation of negative ion concentration in each type of plantation exists 1-2 peaks;the peak appear in the morning or evening;the highest value of negative ion concentration appear in Betula platyphylla,being 1 815 cm-3.The annual variation of concentration of negative ion is in July & September,respectively;the concentration of negative ions of air in Picea koraiensis plantation in July is the highest,being 1 284·cm-3. |
