Study of Negative Air Ions' Dynamic Variation
in Chongqing Typical Locations
Abstract: To study negative air ions' dynamic variation, we choose 3 typical locations in Chongqing as observing sites for one year: central business district - Jiefangbei, new city foreste - Hong'ensi forestry park, natural evergreen foliage foreste - Jinyun mountain natural conservation area. The results indicate: negative air ions' dynamic variation shows similar laws during the observing time; range 3 locations' annual negative air ions consistency, fortable degree and air clean degree from high to low: Jinyun Mountain natural conservation area > Hong'ensi forestry park > Jiefangbei; range negative air ions' consistency and fortale degree in different weather from high to low:rainy > sunshine> cloudy;through observing the CI value and q value pare air quality, Jinyun Mountain natural conservation area >Hong'ensi forestry park >Jiefangbei.

重庆主城典型地段空气负离子动态变化研究
摘要:选取重庆主城三处典型地段:城市中心商务区——解放碑、新建城市森林——鸿恩寺森林公园、天然常绿阔叶林——缙云山自然保护区,进行空气负离子监测,经过1周年的监测,结果表明:监测期内三地测得的负离子浓度变化呈现相似规律;将三个观测地区分别代表的典型区域按全年负离子浓度、空气舒适度、空气清洁度由高到低排列均为:天然林区>新建城市森林>城市中心商务区;三地不同天气条件下的负离子浓度和空气舒适度均表现为:雨天最优,晴天优于阴天;通过监测Q值、CI值比较三地的空气质量,缙云山自然保护区优于鸿恩寺,解放碑空气质量相对较差。

气体分子在某些外力作用下,外层电子会脱离原子核的束缚而离开轨道,成为自由电子,游离的自由电子又会与其他中性的分子相结合,使得到多余电子的气体分子呈负电极性,
