永泰县藤山省级自然保护区负氧离子浓度变化特征

Variation features of negative (oxygen) ions in the Yongtai Tengshan Provincial Nature Reserve

通过搜集2017年5月—2018年5月藤山自然保护区负(氧)离子的监测数据,分析其空气负离子浓度的变化特征,结果显示:1)永泰藤山省级自然保护区空气负(氧)离子浓度高,对人体健康十分有利;2)1～3月负(氧)离子日平均浓度的变幅较大,5月下旬开始到12月底,在全年中处于相对较低水平,多数天数介于1000～2000个·cm-3;3)空气负(氧)离子月平均浓度以6月份最小,4月份最大;4)季节分布服从:春季>冬季>秋季>夏季;5)空气负(氧)离子浓度与空气相对湿度和气温高度相关,空气相对湿度对负氧离子的贡献大于气温。

The variation characteristics of air anion concentration were analyzed by collecting data on the negative (oxygen) ions of the Tengshan Provincial Nature Reserve from May 2017 to May 2018. The results showed that: 1) There had a high concentration of negative (oxygen) ions in the Yongtai Tengshan Provincial Nature Reserve, which was Beneficial to human health. 2) The daily average concentration of negative (oxygen) ions varied greatly from January to March and was relatively low at the end of May to the end of December, with most days ranging from 1000 to 2000 per cubic centimeter. 3) The monthly average concentration of negative (oxygen) ions in air was the smallest in June and the largest in April. 4) The seasonal distribution of air anion concentration from high to low was as below: Spring > Winter > Autumn > Summer. 5) The negative (oxygen) ion concentration of the air was highly correlated with the relative humidity of the air and the temperature, and the relative humidity of the air contributes more to the negative oxygen ions than the temperature.
