在对黔南州林区氧气含量进行实测基础上,运用科学的分析方法,全面评价了黔南州林区森林释氧功能及其对空气质量状况的改善。研究表明:黔南州森林环境空气中氧气平均含量为21.19%,超出正常空气中氧气浓度0.24%,氧气浓度最高的达到21.54o.4,超出正常水平0.59个百分点;森林公园中的氧含量明显高于其他森林环境,平均值高达21.32%,超出正常水平0.37个百分点;针阅混交林空气中氧气浓度最高,为21.26%,其次是针叶林,氧气含量最低的是阔叶林;森林环境中的氧气浓度随着林龄的增长而增加,林木成熟后,氧气浓度随着树木年龄的增长而逐渐下降。

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.
