%X 空气中负氧离子的含量是衡量空气清新程度、评价康养旅游的关键指标之一。本文对2022年6月1日至2023年5月31日象山县塔山公园负氧离子浓度时间变化特征进行了研究&#65292;结果表明&#65306;塔山遗址公园负氧离子浓度和气温呈正相关。夏季负氧离子浓度最高&#65292;冬季最低&#65307;负氧离子浓度日变化呈单峰型分布&#65292;白天高于夜间&#65292;峰值出现在14时&#65292;谷值出现在06时。夏季负氧离子浓度日变化幅度最大且最值出现时次的集中度最高&#65307;降水会影响负氧离子浓度的变化。无雨天气的负氧离子浓度变化幅度最大&#65292;随着雨量增大&#65292;负氧离子浓度与气温相关系数逐渐减小。<br>The content of negative oxygen ions in the air is one of the key indicators to measure the freshness of the air and evaluate health and wellness tourism. This article studies the temporal variation characteristics of negative oxygen ion concentration in Tashan Park, Xiangshan County from June 1, 2022 to May 31, 2023. The results show that the concentration of negative oxygen ions in Tashan Park is positively correlated with temperature. The concentration of negative oxygen ions is the highest in summer and the lowest in winter. The diurnal variation of negative oxygen ion concentration shows an unimodal distribution, with higher values during the daytime than at night, peaking at 14:00 and reaching the trough at 06:00. The diurnal variation of negative oxygen ion concentration in summer has the largest amplitude and the highest concentration of peak values. Precipitation affects the variation of negative oxygen ion concentration. The variation amplitude of negative oxygen ion concentration is the largest on rainless days, and as the rainfall increases, the correlation coefficient between negative oxygen ion concentration and temperature gradually decreases.
