摘　　要：基于2019—2023年衡水湖湿地气象站与饶阳国家气候观象台的NAIC数据和气象资料,探讨衡水湖湿地与饶阳农田的空气负离子浓度特征,并采用通径分析方法分析气象影响因子对衡水湖湿地NAIC的影响。结果表明:衡水湖湿地与饶阳农田的NAIC等级均为2级,但饶阳农田的NAIC年平均值明显低于衡水湖湿地。衡水湖湿地与饶阳农田不同季节的NAIC日变化特征均表现为白天高于夜间,且峰值均出现在白天。衡水湖湿地6月至9月NAIC明显高于其他月份,夏季NAIC明显高于其他季节。饶阳农田8月份和秋季NAIC最高,且各月和各季节的NAIC平均值差异均较小,饶阳农田在不同时间尺度上NAIC水平均低于衡水湖湿地。在衡水湖湿地NAIC气象影响因子通径分析中,RH对NAIC的促进作用最显著,PMAX对NAIC的限制作用最显著,且气象影响因子TMIN、PMAX、PMIN、RH、SS对NAIC的影响主要表现为直接作用,T、P、TMAX、RHMIN对NAIC的影响主要表现为间接作用。Based on the NAIC data and meteorological data from Hengshui Lake wetland meteorological Station and the Raoyang National Climatological Observatory from 2019 to 2023,this study explores the characteristics of air negative ion concentration(NAIC)in Hengshui Lake wetland and Raoyang farmland,and uses path analysis method to analyze the impact of meteorological influencing factors on NAIC of Hengshui Lake wetland.The results showed that Hengshui Lake wetland and Raoyang farmland had an NAIC level of 2,but the annual average NAIC value of Raoyang farmland was significantly lower than that of Hengshui Lake wetland.The daily variation of both NAIC in Hengshui Lake wetland and Raoyang farmland in different seasons show higher values during the day than at night,and the peak occurs during the day.The NAIC of Hengshui Lake wetland from June to September is significantly higher than in other months,and the NAIC in summer is significantly higher than in other seasons.The NAIC of Raoyang farmland is highest in August and autumn,and the differences in the monthly and seasonal average NAIC values are relatively small.The NAIC level of Raoyang farmland is lower than that of Hengshui Lake wetland at different time scales.In the path analysis of meteorological influencing factors on NAIC in Hengshui Lake wetland,(relative humidity)RH has the most significant promoting effect on NAIC,while PMAX has the most significant limiting effect on NAIC.The meteorological impact factors TMIN,PMAX,PMIN,RH,and(sunshine duration)SS mainly have a direct effect on NAIC,while(temperature)T,(precipitation)P,maximum temperature(TMAX),and(minimum relative humidity)RHMIN mainly have an indirect effect on NAIC.
