摘要
[目的]探索不同树种林下的空气负离子水平,以期为城市绿地的规划与建设提供参考。[方法]选择红皮云杉、樟子松、白桦、杏林作为研究对象,对各树种林下的空气负离子浓度和空气质量进行比较研究。[结果]红皮云杉和樟子松林下的空气负离子浓度差异不显著,其他树种间的空气负离子浓度差异极显著。红皮云杉林下空气负离子浓度最高,平均值可达689个/cm3,空气质量较好。杏林下空气负离子浓度明显低于红皮云杉、樟子松和白桦。[结论]不同树种林下的空气负离子浓度和空气质量不同,针叶林下的空气负离子浓度和空气质量要好于阔叶林。
[ Objective] The study aimed to explore the air negative ions concentration in different tree species forests, and provided a reference for planning and construction in urban greenbelt. [ Method ] Choosing Korean spruce forest, Mongolian pine forest, White birch forest and Apricot forest as the objectives, the air negative ions concentration and air quality in different tree species forests were compared. [ Result ] The air negative ions concentration bad no significant difference between Korean spruce and Mongolian pine forest. But it differed significantly with other tree species. Korean spruce forest bad the highest air negative ions concentration and the best air quality, with the average of 689 ions per cubic centimeter. The air negative ions concentration was significantly lower than other study areas in Apricot forest. [ Conclusion ] The air negative ions concentration and air quality in different tree species forests were different, among which, in coniferous forest was better than in broad-leaved forest.
