摘　　要：对天津市4个不同地点(昆仑桥、水上公园、杨柳青庄园和市区空旷地)林木的空气负离子浓度日变化和年变化进行测定,并分析了空气温湿度等环境因素对其影响。结果表明:空气负离子浓度日变化基本呈先增大而后减小的趋势,其最大值多出现在中午左右,不同地点略有不同;空气负离子浓度季节变化趋势基本为夏季>春季>秋季,最大值出现在7月;不同地点空气负离子浓度变化趋势与温湿度变化趋势一致,呈正相关关系;水上公园的空气质量最清洁,市区空旷地质量最差。林木可以提供空气负离子,从而达到净化空气的目的,有利于身体健康。因此,城市建设中应加强植被绿化。Diurnal and annual variation of air negative ions at four different sites（Kunlun Bridge,Water Park,Yangliuqing Manor and field）in Tianjin were studied,influence of air humidity and temperature were analyzed.The results showed that diurnal variation of air negative ions firstly increased and then decreased,and the maximum value mostly occurred at noon which was slightly different in various sites;annual variation of air negative ions presented summer〉spring〉autumn,and maximum occurred in July;the variation tendency of air negative ions was completely similar to that of humiture in different sites,presenting positive correlation;air quality in Water Park was the best of all,and that of field was the worst.Forests could provide air negative ions,consequently purifying the air pollution,which was in favor of human bodies.Therefore,urban landscaping should be enhanced in the city construction.
