摘要:

空气负氧离子具有提高人体免疫力、调节机能平衡的功效,被誉为“空气维生素”,但受区域生态环境条件差异影响,导致合理解释空气负氧离子变化存在不确定性。因此,研究特定区域空气负氧离子浓度特征及其影响因素,对于深入揭示空气负氧离子变化机理及开展区域空气质量评估具有重要意义。本研究以湖北幕阜山区潜山国家森林公园空气负氧离子为研究对象,利用长期动态监测数据,分析了该区域空气负氧离子浓度的日变化、月变化、季节变化等特征和浓度等级评价,并分析负氧离子与气温、相对湿度、风速、PM2.5等环境因素之间的关系,旨在为该区域环境质量评价和生态服务功能评估提供科学依据。结果表明:负氧离子浓度分布呈现出明显的季节变化,夏季最高,冬季最低,总体表现为夏季>秋季>春季>冬季;月均值最大为8月,最小为1月。负氧离子浓度与气温总体上呈正相关关系,与相对湿度和PM2.5总体上呈负相关关系,与风速相关性表现不明显。潜山国家森林公园负氧离子浓度均值为2191个/cm3,具有优异的空气负氧离子生态康养资源。

Abstract:

Air negative oxygen ion has the effect of improving human immunity and regulating function balance and is known as “air vitamin”. However, due to the difference of regional ecological environment conditions, it is uncertain to explain the change of air negative oxygen ion reasonably. Thus, it is of great significance to study the characteristics of air negative oxygen ion concentration and its influencing factors in a specific area for further revealing the change mechanism of air negative oxygen ion and carrying out regional air quality assessment. In this study took air negative oxygen ions in Qianshan National Forest Park of Mufu Mountain area of Hubei Province as the research object, and used the long-term dynamic monitoring data to analyze the characteristics of diurnal, monthly and seasonal variations of the concentration of negative oxygen ions in the air and the assessment of the concentration level. The relationship between negative oxygen ion and air temperature, relative humidity, wind speed, PM2.5 and other environmental factors was studied as well, so as to provide scientific basis for environmental quality assessment and ecological service function assessment in this region. The results showed that the distribution of negative oxygen ion concentration showed obvious seasonal variation, with the highest concentration in summer and the lowest concentration in winter, and the overall pattern was summer > autumn > spring > winter. The maximum monthly mean was in August and the minimum monthly mean was in January. The concentration of negative oxygen ions was positively correlated with air temperature, negatively correlated with relative humidity and PM2.5, and had no obvious correlation with wind speed. The mean concentration of negative oxygen ions in Qianshan National Forest Park was 2191/cm3, which had excellent air negative oxygen ion ecological health resources.
