| 摘 要： | 利用NOAA Earth System Research Laboratory提供的1991─2004年Tae-ahn(韩国)，Ulaan Uul(蒙古)以及瓦里关(中国)的大气温室气体CO2和CH4的数据，对东亚地区大气温室气体的浓度特征及变化趋势进行研究.结果表明:14年来东亚地区大气中φ(CO2)和φ(CH4)月和年平均值总体呈明显上升趋势；3个监测站的φ(CO2)年线性递增率比较接近，平均值为1.91×10-6a-1，季节变化较一致；从沿海到内陆这2种温室气体的浓度均随海拔升高而逐渐降低.

| Abstract: | Utilizing the data of the greenhouse gases (GHGs) of atmosphere from 1991 to 2004 provided by NOAA Earth System Research Laboratory, including carbondioxide and methane data at Korea of Tae-ahn Peninsula, Mongolia of Ulaan Uul and China of Waliguan stations, the atmospheric concentrations and their trends of GHGs in East Asia in 14 years were analyzed. The results show that the monthly and annually averaged concentrations of carbon dioxide and methane in the atmosphere are obviously increasing in East Asia in 14 years. The annual linear incremental rates of carbon dioxide are approximate for three stations,with an average of 1.91×10-6 a-1 and reflecting consistent seasonal variations. From the coast to inland, the concentrations of both the two GHGs decrease gradually with the increase of the altitude. |
