摘　　要：通过连续观测云南省热带作物科学研究所位于芒果山的橡胶种质圃和2006年建成的环境友好型生态胶园不同种植模式空气负氧离子(negative air ion,NAI)浓度,分析了负氧离子浓度变化特征及与相关影响因素之间的关系。结果表明:旱季纯胶林负氧离子浓度最高,其浓度为2980个/cm^(3),雨季和雾凉季均为绿肥地负氧离子浓度最高,浓度分别为5474、2208个/cm^(3),各季节橡胶种质圃负氧离子浓度均最低,分别为1890、2654、1685个/cm^(3);不同季节空气负氧离子浓度比较为:雨季(5-10月份)>旱季(2-4月份)>雾凉季(11月至翌年1月);不同种植模式空气负氧离子浓度比较为:绿肥>诺丽>用材林>纯林>种质圃;负氧离子浓度变化与空气湿度和空气含水量呈显著正相关,相关系数(R)分别为0.545和0.494,与空气相对湿度呈显著负相关,相关系数(R)为-0.169。Negative Air Ion(NAI)concentrations in the air of different planting patterns were continuously observed in the germplasm nursery of Yunnan Tropical Crops Research Institute located in Mango Mountain and the eco-friendly ecological rubber plantation built in 2006.The variation characteristics of NAI concentration and its relationship with related influencing factors were analyzed.The results showed that the highest negative air ion concentration was 2980/cm^(3) in dry season,5474/cm^(3) and 2208/cm^(3) in rainy season and fog-cool season,respectively.The lowest negative oxygen ion concentration was 1890,2654,1685/cm^(3) in each season.The concentration of negative air ions in different seasons was rainy season(May-October)>dry season(February-April)>foggy season(November-January of the next year).The air negative ion concentration of different planting patterns was green manure>noni>timber forest>pure forest>germplasm nursery.The change of negative air ion concentration was significantly positively correlated with air humidity and air water content,and the correlation coefficients(R)were 0.545 and 0.494,respectively.It was significantly negatively correlated with air relative humidity,and the correlation coefficient(R)was-0.169.
