昆明金殿国家森林公园秋冬季节空气负离子分布格局研究

空气负离子浓度是影响森林公园休闲养生旅游可持续发展的关键。研究昆明金殿国家森林公园秋冬季节空气负离子分布特征。结果表明：①空气负离子浓度由高至低为：木兰园〉竹类园〉杜鹃园〉云南油杉林〉茶花园〉森林游道〉太和宫〉钟楼；②空气负离子浓度昼间变化规律为：午前高，中午低，午后又升高；③空气负离子浓度与空气温度的变化趋势相反，与相对湿度的变化趋势一致；④公园空气质量：云南油杉林为B级；森林游道、太和宫、木兰园、竹类园、茶花园、杜鹃园为c级；钟楼为D级。

Distribution Characteristics of Air Anions in Kunming Golden Temple National Forest Park in Autumn and Winter

Air anion concentration is the key to the sustainable development of leisure tourism in forest park. This paper studied on the distribution characteristics of air anions in Kunming Golden Temple Na-tional Forest Park in autumn and winter. The results showed that： ① The order of air anion concentration from high to low was followed as Magnolia Garden 〉 Bamboo Garden 〉 Rhododendron Garden 〉 Ketel-eeria evelyniana Forest 〉 Camellia Garden 〉 Forest Tour Road 〉 Taihe Palace 〉 Bell Tower; ② its di-urnal change pattern showed air anion concentration was high in the morning, then dropped rapidly at noon, then rose in the afternoon; ③The change trend of air anion concentration was opposite to air tem-perature, but kept same trend with relative humidity; ④ Air quality in the Keteleeria evelyniana Forest was grade B; in Forest Tour Road, Taihe Palace, Magnolia Garden, Bamboo Garden, Camellia Garden and Rhododendron Garden was grade C; at Bell Tower was grade D.
