Characteristics of Negative Air Ion Concentrations in Hengshui Lake Wetland and Raoyang Farmland and Path Analysis of Influencing Factors
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.
