空气负氧离子的时空分布特征及其影响因素研究-以福建君子峰国家级自然保护区为例

Spatiotemporal Variation of Air Negative Oxygen Ions and Their Influencing Factors-A Case Study of Junzifeng National Nature Reserve in Fujian

空气负氧离子是评价森林环境质量的重要指标之一,对于调节人体稳态和延缓衰老具有重要作用。2022年3月至2023年2月对福建君子峰国家级自然保护区管理局岩坑、桃源两个监测站空气负氧离子变化进行研究。结果表明:岩坑和桃源两个监测点的年平均空气负氧离子的浓度分别为3798 ion·cm^(−3)和2360 ion·cm^(−3);两个监测点的空气负氧离子浓度呈双峰型,均在5月和11月达到最高值,而此时空气湿度均在90%以上,温度在10~21℃之间。为此,本研究认为空气负氧离子的产生可能受环境温度和湿度的影响。

Negative air ion is one of the important evaluation indexes of forest environmental quality,it also can regulate the steady state and delay senility of human.From March 2022 to February 2023,we conducted the changes of negative oxygen ions in the air at two monitoring stations in Yankeng and Taoyuan of the Junzifeng National Nature Reserve administration bureau in Fujian.The results showed that the annual average air negative oxygen ion in Yankeng and Taoyuan monitoring stations were 3798 ion·cm^(−3)and 2360 ion·cm^(−3),respectively.The concentration of negative oxygen ions in the air at the two monitoring stations showed a bimodal pattern,reaching the highest values in May and November,when the air humidity was above 90%and the temperature was between 10~21℃.So we believed that the production of negative oxygen ions in the air might be affected by ambient temperature and humidity.
