摘　　要：研究负氧离子时间变异格局,以及气象因子对其的影响,可以为开发和利用负氧离子资源、创造优质森林旅游环境提供科学的理论参考。文章选择福州国家森林公园作为研究对象,利用负氧离子浓度定点监测设备检测以分钟为最小时间单位的负氧离子浓度、温湿度数据,结合降水量卫星监测数据,分析负氧离子浓度变化特征及其与气象影响因子的关系。结果表明:1)福州国家森林公园负氧离子资源较为丰富,全年浓度较高;2)负氧离子浓度日变化特征呈现白天低、晚上高的单峰单谷特征;3)负氧离子浓度呈现夏季>冬季>秋季>春季的明显季节变化特征,年均变化幅度达到346个/cm^(3);4)负氧离子浓度变化与气象影响因子有关,中雨及以上降水天气和闪电活动与负氧离子浓度存在显著的相关关系,负氧离子浓度雨天最大,雷雨天气小于雨天,晴天与多云天气均较小,且闪电活动后24 h会显著升高。因此,在闪电活动、中雨及大雨过后的24 h负氧离子浓度达到较高水平,适合进行森林旅游、康养等相关活动。The study of spatial-temporal variation pattern of negative oxygen ions and the influence of meteorological factors on the pattern can provide scientific theoretical reference for developing and utilizing negative oxygen ion and creating high quality environment for forest tourism.The paper chooses Fuzhou National Forest Park to record the data on negative oxygen ion,temperature and humidity,with minute as the minimal unit time,using the fixed-point monitoring equipment,and analyze the relationship between the variation characteristics of negative oxygen ion and meteorological influencing factors satellite using monitoring data on precipitation.The results are as follows:1)Fuzhou National Forest Park boasts abundant negative oxygen ion,with high concentrations year-round;2)The diurnal change in negative oxygen ion concentration presents the unimodal and single-valley characteristic,which goes down in the daytime and rises at night;3)The negative oxygen ion concentration shows obvious seasonal variation,with the ranking as summer>winter>autumn>spring,and the annual change ranges amount to 346 cm-3;and 4)The change of negative oxygen ion concentration is related to meteorological factors.In moderate and worse rain weather,climatic condition and lightning are significantly correlated with negative oxygen ion concentration.The concentration of negative oxygen ion is the highest in rainy days,followed by the concentration in thunderstorm days.The concentration is relatively small in sunny and cloudy days,but will significantly rise 24 hours later after lightening.It is concluded that the concentration of negative oxygen ions is relatively high 24 hours after lightning,moderate rain and heavy rain,which is suitable for forest tourism,forest therapy and other outdoor activities.
