【摘要】 在不同季节对鹅凰嶂自然保护区不同地点（缓冲区和实验区）的不同位置（林内和林缘）的空气负离子浓度进行了观测,结果表明,鹅凰嶂自然保护区的空气负离子浓度介于1 198⁵ 842个·cm^-3之间,在季节上表现为雨季>旱季,在空间上表现为缓冲区>实验区,林内>林缘。空气负离子浓度与气温、相对湿度均极显著正相关（P<0.01）。林内/林缘位置对空气负离子浓度有显著影响,表明森林微环境对提供空气负离子起着重要作用。更多还原

【Abstract】 The spatiotemporal distribution of negative air ion（NAI） was investigated in Ehuangzhang Nature Reserve.The NAI concentration in different sites（buffer zone and trial zone）,positions（inner and edge of forest） and different seasons（rainy and dry season） were compared.The relationships between NAI concentration and environmental factors（air temperature and relative humidity） were analyzed.The results showed that NAI concentrations ranged from1 198 to 5 842 ions ? cm^-3.Generally,the concentration distribution follows the trend that rainy season > dry season,buffer zone > trial zone,and inner zone > edge zone.NAI concentration was significantly positively correlated with air temperature and relative humidity respectively.Position had significant influence on NAI concentration,indicating that forest micro-environment played a significant role in NAI concentration.更多还原
