摘要
对我国亚热带森林地区的非甲烷碳氢化合物(NMHC)、一氧化碳、氮氧化物等进行了两个月的连续采样,并利用气相色谱仪对NMHC进行了分析,得到大量NMHC的实测资料,并对它们的日变化规律和相互之间的关系做了详细研究。分析表明,温度对各种树木异戊二烯的排放来说是一个重要因子,而且各种植物排放的异戊二烯对温度的依赖关系基本上比较一致。对于我国亚热带森林主要树种异戊二烯的排放速率进行了初步测定。
Two months Continuous measurement at subtropical forest of Dinghushan is carried out for the first time. Air samples were analyzed by using gas chromatograph with a flame ionization detector. Lots of NMHC data at subtropical forest of Dinghushan is obtained, their diurnal variation and relationship are studied in detail. Analyzing results indicate that temperature is the most important affecting factor for isoprene concentration and its emission for various plants, the correlation coefficient between isoprene concentration of various plants and temperature is basically consistent. The emission flux of isoprene from major species in subtropical forest is also measured.
