摘要: 为了研究不同下垫面的空气负离子浓度是否存在显著差异,选取漠河北极村境内针叶林(樟子松)、阔叶林(桦树)、针阔混交林(樟桦混交)、湿地、草地、空地等6种不同下垫面进行对比观测分析。每种下垫面选取一个观测区进行负离子浓度测量,共6个观测区。实地监测空气负离子浓度,并对实测数据进行筛选剔除异常值。利用SPSS进行数据统计,分析不同下垫面间负离子浓度差异。通过研究分析得出结论,6种不同下垫面间的空气负离子浓度存在显著差异。针叶林负离子浓度>针阔混交林负离子浓度>阔叶林负离子浓度>湿地负离子浓度>草地负离子浓度>空地负离子浓度。针叶林、针阔混交林的空气质量都达到了最清洁程度,湿地、阔叶林达到了清洁程度。

Abstract: To study whether there is a significant difference in the concentration of air anion in different underlying surfaces, we comparatively analyzed 6 different underlying surfaces in the Arctic village of Mohe including coniferous forest (sylvestris), broad-leaved forest (birch), coniferous and broad-leaved mixed forest (camphor mixed), wetlands, grassland and open space. Each observation area was selected for each underlying surface to measure the air anion concentration, a total of 6 observation areas. In the local observation air anion concentration data, outliers were filtered and removed. We used SPSS to analyze the difference of air anion concentration in different underlying surfaces. The results showed that: there were significant differences in air anion concentration in 6 different underlying surfaces, and anion concentration from high to low were coniferous forest, coniferous and broad-leaved mixed forest, broad-leaved forest, wetlands, grassland and open space. The air quality of coniferous forest, coniferous and broad-leaved mixed forest reached the highest level of cleanliness, and that of wetland and broad-leaved forest reached the level of cleanliness.
