摘　　要：利用河南黄河小浪底地球关键带国家野外科学观测研究站的空气负离子和气象数据,分析春旱期典型天气条件下,河南省济源市南山森林公园人工侧柏林中的空气负离子浓度与气象因子的关系.结果表明:①晴天和阴天空气负离子浓度日变化呈“U”形曲线,雨天呈单峰曲线;日均空气负离子浓度雨天>晴天>阴天.②温度、相对湿度、风速和饱和水汽压亏缺均对空气负离子浓度有显著影响:晴天时,温度、风速和饱和水汽压亏缺与空气中负离子浓度呈极显著负相关,相对湿度与空气负离子浓度呈显著正相关;阴天时,温度、风速和饱和水汽压亏缺与空气负离子浓度呈极显著负相关;雨天时,温度、风速和饱和水汽压亏缺与空气负离子浓度呈显著正相关,相对湿度与空气负离子浓度呈显著负相关.Data of the negative air ions and meteorological factors,acquired from the Yellow River Xiaolangdi Earth Critical Zone National Field Scientific Observation and Research Station of Henan,were used to analyze the variation of air negative ion concentration of Platycladus orientalis forest under typical weathers and its relation with meteorological factors in spring drought period.The result showed:①The diurnal variation of negative ions concentration on sunny and cloudy days both showed“U”shape trend,and single-peak trend on rainy days,and the sequence of daily average value of negative air ions concentration was rainy days>sunny days>cloudy days.②Air temperature(TA),relative humidity(RH),vapor pressure deficit(VPD)and wind speed(WS)had significant relationship with negative air ion concentration.On sunny days,TA,VPD and WS showed highly negative correlations with NAI concentration significantly.RH showed a significant positive correlation with NAI concentration;On cloudy days,VPD and WS showed highly negative correlations on NAI concentration significantly;On rainy days,TA,VPD,and WS showed positive correlations with NAI concentration significantly.RH showed a significant negative correlation to NAI concentration.
