为了了解不同类型绿地空气负离子的变化规律,并为城镇绿化的合理配置提供科学依据,以福州市公园绿地、居住绿地、工业绿地和公共设施绿地（包括大学校园绿地和商业绿地）5种类型绿地作为研究对象,对其空气负离子效应变化规律进行了研究。结果表明,不同类型绿地空气负离子浓度存在明显的差异,空气负离子浓度的大小顺序依次为公园绿地〉校园绿地〉居住绿地〉商业绿地〉工业绿地,单极系数依次逐渐增大,空气离子评价系数却逐渐减小;不同绿化配置模式的绿地空气负离子浓度也存在明显的差异,浓度大小、空气质量优劣的排序均为复层林〉乔草型〉灌草型〉草地〉裸地;公园绿地、校园绿地和居住绿地日变化较为平缓,空气负离子浓度呈直线下降的趋势,商业绿地则为单谷形式,而工业绿地为双谷形式;不同绿化配置模式的空气负离子浓度日变化曲线趋势基本一致,均呈现单调递减的趋势。

The aim of this study is to provide a theoretical basis for choosing suitable pattern for urban afforestation by analyzing the change regular of air negative charge ions concentration (ANCIC) in different types of green space. The ANCIC in different types of green space in Fuzhou City were studied in this paper. The results showed that the ANCIC was in the order of the public green space〉 educational green space〉 residential green space〉 commercial green space〉 industrial green space, ion polarity ratio increased gradually in the order too, while the air ion assessment index decreased. The ANCIC and the air quality were in the order of tree-shrub-grass〉 tree-grass〉 shrub-grass〉 grass〉 the bare. The diurnal change pattern of ANCIC was more moderate, almost linear decline in the public green space, educational green space and residential green space, but which was of single valley in commercial green, dual valley in industrial green space. The diurnal change pattern of ANCIC was the same in different types of green space structure, which was monotone decreasing.
