摘要
选择南方有代表性的森林游憩区进行森林环境中空气负离子水平研究 ,结果表明 :(1)不同林分类型的森林环境中空气负离子水平差异较大。 (2 )森林环境中空气负离子浓度与温度成显著负相关 ,与空气相对湿度成正相关。 (3)森林游憩区中水体对负离子水平的影响较大。其中动态水大于静态水 ,瀑布大于溪流。(4)森林中空气负离子浓度还呈现出一定的日变化和年变化。 (5 )建筑材料对空气负离子水平也有一定的影响。
The studies on the concentration of aero anion in some south China forest recreation areas showed: (1) The aero anion concentration has differences in different forest types. (2) In forest surroundings, the correlation between aero anion concentration with temperature and moisture are significant. (3) Water body has different effect on aero anion concentration in forest recreation areas. (4) There have been aero anion daily variance and yearly variance. (5) The structural material has effect on aero-anion concentration.
