2012 年8月应用 FTP-2 空气负离子测量仪对湖南省森林植物园

3 个生态区及全园的 空气正、负离子浓度进行测量,并采用日本的空气质量评价指数(IC)对其空气质量作了评价.结果表明:(1) 湖南省森林植物园空气负离子浓度垂直变化明显,园中高于园内其他地方.空气离子评价系数(IC)均大于 0.93, 属于清洁,空气质量很好.(2)从空旷地向水区空气负离子浓度和空气质量(IC)逐渐增加 , 有林地区空气负 离子浓度明显高于无林地区;

有瀑布和水流等动态水地区空气负离子浓度明显增加;

园中不同功能区空气负离 子浓度和空气质量差异显著,其大小依次为水边>

2008 to August 2009, the positive and negative ions concentrations of air in Hunan Forest Botanical Garden (whole forest park and its three ecological regions) were measured by using FTP-2 aero anion measuring instrument, and by adopting Japanese Evaluating Indicator(CI), the air quality of the park was evaluated. The results are as follows. (1) The air ion concentration of the forest botanical garden of Hunan province changed obviously in the vertical direction, and that in the garden was higher than that at other places inside the park. (2)The negative air ion concentrations and CI increased gradually from the clearing to water zone, the negative air ion concentrations in forested areas were obviously higher than those in non-forested areas;

the negative air ion concentrations obviously increased in the areas where the moving waters, such as waterfall and rivulet;

the air ion concentration and air quality in different functional areas were different each other in the park, and the descending sequence is: that at the waterside that in the forest that in the hollowness. (3) the diurnal variation curves of air-anion concentration and the air quality showed a double peak type, the general rules were high in the morning low in the afternoon;
