Analysis on the Oxygen Content of Forest Environment in Qiannan Guizhou Province
Abstract：This paper studied on t the oxygen content of the Qiannan forest areas by scientific method of analysis to compre- hensive evaluate the ruction of oxygen and effection on the improvement of air quality status the Qiannan Forest. Results showed that： the average oxygen content of air was21.19% in the Qiannan forest environment, which was higher 0.24% than normal air oxygen concentration, the highest oxygen concentration reached 21.54 percent, which beyond the normal level 0.59 per- centage points; the oxygen content was significantly higher in the forest park than other forest environment, the average up to 21.32 percent, which beyond the normal level 0.37 percentage points;the air oxygen concentration in broadleaved mixed forest was higest,which was21.26%, followed by coniferous forest, the least was broad--leaved forest; the oxygen concentration increased with the growth of forest age, in the forest environment, but when the trees mature, the oxygen concentration decreased gradually as the trees grew older.
