摘要
主要对茶山竹海夏季负氧离子浓度分布状况、负氧离子日变化特征及负氧离子与地表植被、温度、湿度的关系进行了初步探索,研究结果显示:负氧离子浓度最大值以薄刀岭最高,为28400个/cm3,均值以大岚垭最高,为15700个/cm3,达到《森林环境中空气负离子浓度分级标准》Ⅰ级水平,极利于人体健康;尖叶竹林中负氧离子浓度高于阔叶林;负氧离子浓度在每天15时左右达到最大值,平均为24500个/cm3;负氧离子浓度与温度、湿度均呈正相关系。
Some primary explorations on distribution and daily variation characteristics of negative oxygen ion concentration, and the Relationship among negative oxygen ion concentration, surface vegetation, temperature and humidity in ChaShanZhuHai were presented. The results showed that negative oxygen ion concentration was at the highest in BoDaoLing with concentration of 28400 ind/cm^3 , the average concentration of negative oxygen ion was highest in DaLaYa with the level of 15700 ind/cm^3 , the concentration of negative oxygen ion which met the first order of grading standard of Forest Environment Air was very beneficial to health; the concentration of negative oxygen ion of bamboo forest was higher than that in broadleaf forest; the peak values of negative oxygen ion concentration appeared at 15：00 with average concentration of 24500 ind/cm^3 every day; there was a positive correlation between negative oxygen ion concentration and temperature , and a positive correlation between negative oxygen ion concentration and humidity was also discovered.
