摘  要:
利用手持式空气负氧离子测量仪,于2019年4月4日、10日、18日先后对龙岩市的新罗区、永定区、连城县等多个区域,同个区域不同地点进行负氧离子测量,探讨不同区域的负氧离子浓度的差异.结果表明,不同区域的负氧离子浓度存在着较明显的差异,从市区→郊区→林缘→森林的负氧离子浓度呈现出逐渐增大的趋势;负氧离子浓度与周围植被疏密、通风情况、离水源地距离等有密切联系,通风条件好且离水源地近的区域,负氧离子浓度明显增大,表现出了区域的局部性特征;某区域的一个测量值不能够真实地反映该区域的负氧离子浓度,应进行连续的观测,才能综合反映该区域空气负氧离子浓度值.

摘  要:
On April 4,10 and 18,2019,the negative oxygen ion concentration in Xinluo District,Yongding District and Liancheng County of Longyan City was measured by hand-held air negative oxygen ion measuring instrument,and the difference of negative oxygen ion concentration in different areas was discussed.The results show that there are obvious differences in the concentration of negative oxygen ions in different regions.The concentration of negative oxygen ions increases gradually from urban area to suburb to forest edge to forest edge.The concentration of negative oxygen ions is closely related to vegetation density,ventilation and distance from water source.The concentration of negative oxygen ions increases significantly in areas with good ventilation conditions and close to water source.It shows the local characteristics of the region;a measured value in a region can not truly reflect the concentration of negative oxygen ions in the region,so continuous observation should be carried out in order to reflect the concentration of negative oxygen ions in the region comprehensively.
