摘要:
 空气负氧离子浓度是评价空气质量的重要指标之一,空气负氧离子浓度高低直接影响空气清新指数和人体健康。在福建省永泰县辖区内选取102个空气负氧离子浓度监测点,运用地统计学Kriging插值评价夏季永泰县空气负氧离子总体分布与空气清新等级。结果表明:1)永泰县夏季空气负氧离子平均浓度为1 013.26个/cm3,其中靠近水源或林地的监测点负氧离子浓度较高;2)永泰县负氧离子浓度服从正态分布,采用四球模型作为半变异函数模型进行空间插值最优;3)永泰县负氧离子由随机变异和结构变异引起的空间异质性比例为59.86%,具有中等空间自相关性,以县城为中心,向四周递增,呈现规则条带及斑块状分布,全县空气负离子平均浓度达到大气清新度指数发布3级以上、有利于人体健康的面积达到99.78%,水平整体较好。
Abstract:
 The concentration of air negative oxygen ions (ANOI) is an important indicator to evaluate the air quality,which directly affects the air freshening index and human health.A total of 102 points for ANOI concentration monitoring were selected in the region of Yongtai County,Fujian Province,and the geostatistical Kriging interpolation was used to evaluate the overall distribution of ANOI and air freshening level in summer.The results showed that :1) The average concentration of ANOI in summer in Yongtai County was 1 013.26 /cm3,and the concentration of ANOI was relatively high in adjacent to water sources or forest land.2) The concentration of ANOI obeyed the normal distribution,and the four-ball model was used as the optimum semi-variogram model for the spatial interpolation.3) The proportion of spatial heterogeneity caused by random variation and structural variation in ANOI in Yongtai County was 59.86%,with moderate spatial autocorrelation.The concentration of ANOI was the minimum in the county downtown and were increasing around its periphery,which showed a regular bands and patchy distribution.The average concentration of ANOI in the county reached the third level of air freshness index,and the proportion of beneficial area to human health reached at 99.78%,and the ANOI concentration level was better in general.
