Abstract

To research characteristics of changes in negative air ion concentration and their relationships with environmental factors in the Mount Tianmu Nature Reserve，measurements were made with an air ion measuring instrument，a microcomputer laser dust collecting instrument，and a temperature-humidity recorder. Then，diurnal variations （08：00－17：00） and annual variations were tested with a correlation analysis between negative air ions and 1） particle matter with aerodynamic diameter ＜10 μm，2） relative humidity，and 3） air temperature. Results showed that negative air ion concentration for selected plant communities was in the following order：Cryptomeria fortunei （1 331 particle·cm-3）＞ Phoebe sheareri （1 223 particle·cm-3）＞ Ginkgo biloba （960 particle·cm-3）＞ Phyllostachys pubescens （701 particle·cm-3）. Diurnal variations of negative air ion concentration was significantly and negatively correlated with PM10（r= －0.812，P＜0.01），significantly and positively correlated with relative humidity （r=0.820，P＜0.01），and significantly and negatively correlated with air temperature （r= －0.676，P＜0.05）. Therefore，dynamic water movement，such as from waterfalls and streams，could increase the negative air ion concentration. ［Ch，4 fig. 2 tab. 23 ref.］
